We came across Jammin’ Jars after watching a few Twitch streamers play it. Out of the gate, we noticed the RTP wasn’t good. It wasn’t until we saw one of the streamers make a huge sum of money on one bonus run. This is when we decided to dig in and see what we can find out about Jammin’ Jars. Is it a game you should be playing?

This is the case study of playing over 65 different rounds.

Jammin Jars Slot Bonus Features. Any of the same 5+ symbols clusters reward a win. Every win cluster is removed and new random symbols are dropped on the grid. A shiny and smiling jar. Game developer Push Gaming has announced the upcoming launch of Jammin' Jars 2, which will be debuting in June of this year.

Here are the Baseline Factors

1. This is on a demo account – No Real Money was used.
2. Each Round had a 5000 Euro balance and a min/max of 500 spins.
3. Our price per spin was 40 Euro. – We know this is a lot for a balance of 5000 euro but it made the case study very interesting.

You may ask how we can trust a demo game vs real money? Well, this is a great question. There are a lot of games you can’t get good feedback on demo accounts. However, Jammin Jars is not the average. The numbers below will share all the details on why we think our numbers would have been the same on real money operators like Slotty Vegas or Leo Vegas. ***Disclaimer at the Bottom***

Game Play and Rules

Jammin’ Jars can be a very volatile slot. It’s almost like you need to be in the right place at the right time. You can make a fortune and you can also lose your whole balance in no time.

This slot was developed by Push Gaming. The graphics are really nice. The gameplay is fast so be ready to act on your spin button. You can only activate autoplay 100 spins at a time. Any more than that could get you in trouble

The goal of the game is simple. You want to have as many fruit symbols line up together on the screen as possible. This goes both up and down. The Better the fruit the bigger payout. You can see the screenshot below that shares some of the returns you will receive on a 40 euro bet. These numbers will of course change based on the bet amount. The minimum amount of fruit you need to be connected to win is five.

You can see in this screenshot that we have three different symbols paying on one screen. The more you have connected the higher the number will go.

Rainbow Feature

Although a nice feature to have in the game, most of the times it doesn’t payout enough for it to affect your balance all that much. Of course, there are certain times when you catch a nice win. This usually happens when you have a jar on the screen with a multiplier and the feature drops right on that location. In this case, you will see some good returns. The image below shows what happens when the feature is applied.

Let’s Dig Into Our Jammin’ Jars Case Study

The best way to do this is to go day by day and round by round. We took pretty strong notes for each round. This will show how our balances went up and down throughout our play. A tally of our total numbers will be at the bottom of this section.

Day One

Round One – Busted 5000 in 195 spins. No free spins were rewarded.

Round Two – A 12k hit came within the free games. 40 spins in. A good balance booster for sure. Our first bonus came after 160 spins and it was a very nice 7.5k. We got a 2nd free spin activated with 260 spins total on this round but it only produced 152 euro. We got our third free spin game 290 spins in and it gave us a 4th jar with a decent win. The jars jammed together nice. We saw x10 on one of the jars. 3886 was the biggest win during that bonus session. The total win was 5694 euro. With 30 spins left out of the max of 500 spins, we hit the big one. The real big one. Jammin Jars set us up for a very long time. You can see the screenshots below. They just kept getting bigger and bigger. We ended up with a bonus spin of 688k. One of the free spin games made up for 616k. We saw 4 jars all within reach and the multiplier was enormous, more than 13 and one got up to 24x. This came real early in our case study but you’ll see this doesn’t happen often, even on demo.

Round Three – Won 1.7k after only playing 30 spins in the free game. Not a bad start. We got our 2nd bonus game within the first 60 spins. We had a good little run that pushed 1.4k. Again, not bad at all. We saw our balance climbing. Our third bonus game came on our 88th spin. It only produced 356 euros. We had a decent first 200 spins but the last 100 gave us a lot of dead spins. Our account dropped to 1.4k when starting the next 100. We then got crushed pretty bad into our 400 range of spins and the balance went to 0 before we maxed our 500 spins.

Round Four – Just a whole bunch of dead spins.

Round Five – Just a whole bunch of dead spins.

Round Six – We got some action early getting a small boost and then things fizzled out. We played more spins but we never saw the bonus game and our balance went to 0.

Day Two

Round One – Great start with round one on day two. We played 100 spins and on the 110th spin, we hit two jars that got up to 10x and 11x. These hit some big lines giving us a win of over 24k. 10 spins later we got the bonus game which gave another 1.4k. And then 20 spins later we hit another two jar game. These jars ran up to 9x each. Our total run on that was 7.8k. Within about another 50 spins we hit another 4 jar bonus. This only led us to 428 euro. Not a big win but the game is acting nice for sure. As soon as that bonus was done soon after we got another. It ended up being another 567. We did get a gameplay fruity win of 1.6k that helped seal a nice win in round one. Actually we received a late surprise and got another bonus game which gave us 657.

Round Two – It was a slow start to this round but then we hit a couple of big rainbow features followed by a big bonus. In fact, we had a 4 jar bonus and we hit it big with a 13.9k win. Three jars were working together. It was really fun to watch.

Day Three

Round One – Within 25 spins we got a bonus game. The jars were in perfect position but it didn’t fulfill the dream this time out. We got 943 euros in return. It took another 150 spins to get another bonus. We started seeing our balance drop fast from dead spins. We picked up some sweet jars and grabbed a win for 7.3k. After this bonus, we went slightly dead. We saw our balance drop back to the starting point over a couple of hundred spins. We did see some wins but not enough to put us in great shape. It wasn’t until our balance dropped way below our starting balance and with 40 spins left in the round we hit it big. 8.7k euro win on regular games with two jars bouncing together each getting to 11x. It was fun to watch. We mad out ahead in this round.

Round Two – We received our first bonus with a pretty spread out jar placement. This came early in the game. The 6 spins gave us a small boost at 1.1k. After this, we really didn’t see much action and our balance went to 0.

Round Three – We caught a rainbow feature 30 spins in and hit a big raspberry with a 4x jar. It gave us a nice win of 1.9k. Our balance dropped off hard after that. We saw little action but the next 100 spins didn’t do much. Zero bonuses set us up for a bad spiral. We went broke after 300 spins. Not a great round.

Round Four – With 70 euro left on the balance we hit a bonus game. The end result of the bonus game was 582. It didn’t last long and we busted out.

Round Five – Not much action in the first 100 spins. We saw our balance drop 35%. Within 200 spins we got destroyed. There was nothing good about this round.

Round Six – The first 100 did absolutely nothing in this round. 150 spins in we hit our first bonus in two rounds. We had the best placement for the jars but we got nothing out of it. 228 was our final take on that bonus game. We got a nice 1k clip on an in-game jar that went up to 10x. It helped the balance that was about to die. Another saving bonus didn’t come and we ended up losing the balance once again.

Round Seven – Brutal round. It was over before we knew it. Not a great way to finish. We are going after one more on this day to see if we can make it up a little bit.

Round Eight – The first 100 spins dropped us down to 3400. We then continued to spin. We did get a fruity win off a feature play which boosted the balance 1.1 k. Without much boosting we jumped into the 300 spin direction and hit our first bonus. The placement wasn’t that great and although one of the jars jumped to 9x we only pulled in 452. In the end, we ended up losing the rest of the balance. We had very little action after the bonus feature.

Not the Best Day

Day Four

Round One – We had some communication errors at the start which may or may not skew results. We got about 50 spins in and the game would say communication error. Well, after 160 spins the balance went flat. Not a good first round to start the day.

Round Two – We got a fruity win in gameplay for 900 pretty early. I hope this gives way to a bonus game. Not much happening after the early win. Getting deep into the 200’s of spins we hit two jars that spiked up to 20k. It was one of our biggest non-bonus wins to date. This was a significant boost. Then we hit a 4 jar bonus which paid out huge. We were seeing multipliers of 12x and 15x. The placements were fantastic. It’s so much fun to see them jump when the two multipliers work together. In the end, we got 28.4k during the bonus. In our final 100 spins, we caught another bonus which started off slow but we were able to make some nice money for 4.3k total. One of the better rounds. To top things off we got an in-game win of 2.2k with two jars working together. So Wow. This was an ideal Round for sure.

Rounds Three – Right out of the gate we hit a bonus for 2.8k. A nice bump for sure. We actually got 4 jars and although we missed some big potential you have to take what you get sometimes. Our balance was starting to drift lower as the game went on. We hit a 5x Apple on a featured game that gave us 1.6k. It’s keeping us alive at this point. We got a bonus late for 1.1k but our balance is still in trouble. We even got a 4th jar early on. We got to about 470 spins and our balance ran out. It was a fight,

Round Four – The first 100 spins went pretty quick. Near the end, we did receive a two jar fruity win for 900. This gave us a little bounce back from the initial 100 spin losses. No bonuses in this game and we saw our balance go to zero in just over 200 spins.

Round Five – Well, this round was amazing. We had a tight group of multipliers the whole time and the big numbers just kept rolling in. It was fantastic. Jammin wins all over the place. It was phenomenal. We had multipliers of 1, 8,18 and 21. At one point we had three working together. In the end, we made over 51k. It was a very exciting moment. Only 30 spins later we got another bonus. This time it was not as great but still worthy. It gave us another 5.1k. This is a great round. We ended up taking in some significant cash. Our biggest on this date.

Round Six – 20 spins in we got our first bonus. We ended up taking 544 on that bonus. The multipliers were never really together nor did the go up enough to give a big win. We ended up going straight down after that small bonus.

Round Seven – We got a fruity win 50 spins into the opening of the game. It paid out 1k but we were already down 2k so it only helped a little. Our next bonus came 50 spins after our first bonus. Which is really impressive. It was a slow roll on up but the final two spins made it pay. We earned 3.2k on this bonus. We did get the third bonus and it only paid 318. Followed up by a 1700 fruity win which was nice for sure. It got us back into the green. Then another bonus came in. We had some very spread out jars but they were working hard. We got 2.2k out of it. To add to the round we had a 2.2k juicy win with two jars working together. We then got a fifth bonus game. This gave us 944. Not great for 5 bonuses. Seems to be the course. We got a fruity win soon after for 1.5k. Well, things kept getting more interesting. We hit another bonus for 888. This was our 6th bonus in the game. After all of those bonuses, we still ended in the red. We had some nice plays but nothing turned strong enough to handle our 500 spins.

Round Eight – In this round we got smoked. Nothing happened. Straight down once we started.

Round Nine – Slow out of the gate but 55 spins in we received a huge 1.5k feature game with a raspberry. Helped for a clean win. 20 spins after we hit a 1k huge plum feature win. It went down from there busting our balance.

Round Ten – 80 spins into this round we go a bonus worth 550. Two spins later we got another bonus. This bonus gave us 572. So no big wins here by any stretch. Entering our next bunch of spins we had 2 jars in the middle working it. They produced 1.5k. We started to go down and we hit another bonus. The only issue with that was it rewarded us 16. We got a two jar fruity win for 845. It put our balance within a good spot but a bonus is critical now. The good news is right after those two jars we got another one. for 1.5k Then another fruity win with two jars gave us 822. Our balance is at 2800 at this point. It started kicking in and we got a bonus. It only paid 532. Somehow this round kept going and after 430 spins the balance went bust. We had a lot working for us but it wasn’t big enough.

Round Eleven – We got a bonus 30 spins in that gave us 732. It fell off after that.

Day Five

Round One – Five spins in we got a bonus for 958. Nothing really happened between this and our 200th spin. We got another bonus that started to shape up nicely with the jar placement but in the end, we only got 578. Another 50 spins later we got another bonus but it only paid 108. With 300 left on the balance, we got our 4th bonus. This paid out 125. Not a great end to this round.

Round Two – Not much happening in this round. Just a slow bleed after the first 100 spins. This round ended with nothing.

Round Three – We got our first bonus 3 spins in. Just like that this bonus game was lame. It gave us 138. Not what you want to see. A 4th jar dropped on the 5th spin.

Round Four – The first 100 spins were dead in this round. This was straight down destruction. Not a good round for us.

Round Five – The first 100 spins went really fast without any wins worth talking about. After 230 spins our beating was complete. We’ll hope for better outcomes.

Round Six – We had a nice 1k fruity win with two jars dancing around a bit. We got a pretty decent bonus of about 150 spins in. It gave us 2.1k. We had two jars working together early but they eventually spread out when it really counted. We were lucky a few spins later to get a 2.7k win from two jars hanging tight. Another bonus came after we saw some drops in the balance. We had a couple of good spins but nothing great in the end. We took 1.4k. Another bonus came around and it gave us 696. We are still below our starting balance at this point but it’s holding on. It was a grind this round and although we didn’t hit 0 it was hard-fought.

Round Seven – We had a nice two jar run that gave 3.7k. We also saw some other minor wins that put our balance in a good spot within the first 100 spins. Another two jar fruity win hooked us with another 1k. We started to see the balance drop and we got the third jar with 4 spaces left for it to fit. However, it only gave us 286. Things were starting to look ugly. We then hit a bonus for 1.4k which might have saved us from going down hard. In the end, we were able to play the 500 spins but our balance ended up at 1612. Not the best of fortunes.

Round Eight – We were about to be squashed when we hit a 2 jar for 1.5k and then got down low as well. Then we hit a Jammin win on two jars sticking together for 23.4k. That puts us in the game now. We closed the 500 spins out with a small bonus win of 732. This was a decent round after that two jar win. We lost a lot of the gained we made on it but overall a win.

Round Nine – We got a bonus 17 spins in and we received 172. Not the start we wanted of course. After bleeding under 1000 we hit bonus for 100. This is not a good round for sure. We did hit a 1.2k hit late which helped the ending. This game went downhill and we lost the balance.

Round Ten – This was just a plain disaster. Over in no time.

Round Eleven – Nothing in the first 100 spins. We caught a 1.3 fruity win with two jars hanging around. We’ve had better luck with the two jars than the bonus. We watched this go to 0 pretty quick

Round Twelve – This was our third game in a row without a bonus. Not to mention the previous games before that had real poor bonus payouts.

Day Six

Round One – Our first balance of the day was getting hit pretty hard. We ended up getting a bonus with 800 left only to win 800. Fortunately, we scored another bonus soon after. We actually had a really nice and a 4th jar was added. This was the bonus you wish for every time. 6 great spins with big multipliers. We received a Jammin win with 25.2k for our round. We did get another bonus late in the round but it was only for 330. The rich get richer. 2 spins later we received another bonus. We actually got two jars working together which paid out decent. A total of 2.7k. We then got another bonus for a win of 1.1k. Considering we were down in the dirt and then hit the big win this was our best round in a while.

Round Two – This round was not a good follow up to the previous round. Went to 0 in under 200 spins.

Round Three – Another disaster round for us. Two rounds after the still no bonus.

Round Four – We got our first bonus in three rounds. Turns out it was for 644. It was all downhill after the bonus.

Round Five – A nice bonus with 4 jars came in around the 110th spin. It gave a nice boost of 7.2k. The balance started bleeding after the bonus until we got a 1.1k featured win. We made it through 500 spins but all of our gains were lost for the most part.

Round Six – Things were in a downfall when we hit a 4k strawberry featured spin. It got us in the green for sure after 180 spins. Things definitely fell off again to about 400 and we hit a two jar fruity win for 3.5k win. Ended up with a balance but way below after 500 spins.

Round Seven – We got a bonus 4 spins in with four jars and it paid us 232. What a waste. This was a slow bleeding round that left us at zero in the end.

Round Eight – Got off to a hot start with a huge strawberry win with a 2x jar. This win gave us 3.5k in all.

Round Nine – 7.24 win in the first 50 spins. We ended up dropping to zero with no good winning spins after the initial hit.

Day Seven

Round One – This was a straight downhill disaster.

Round Two – We had a 4 jar bonus midway through the first 100 spins. Nothing was connecting and we received 192. Things were looking bleak until we hit a nice bonus of 4.3k. Our balance was actually at 500 at the time. Saved. After that bonus, the downward spiral began. We dropped to a zero balance.

Round Three – This round was another round of no fun. We got beat up real quick.

Round Four – We hit a bonus several spins into the next round. It played out okay. It could always be better but 1.5k was the gain on this one.

Round Five – This round is starting off just like the others today. Not good. We lost our whole balance within 150 spins.

Round Six – Things were looking the same as the previous 5 rounds and we hit a bonus. Of course, again it wasn’t very good. Only 232 was pulled out. The streak continued and we hit the bottom of the barrel again.

Round Seven – 100 spins in and a straight downhill run. Finally, after almost hitting the bottom we hit a jamming win with one jar getting passed around up to 8x and a featured spin cam through with a strawberry. This was 4k x the 8x jar for 24k. A nice win after 6 dead games. We ended up getting another bonus and some two jar action giving us a nice total win.

Round Eight – A nice 4.7k bonus to get things early in round eight today. We saw our balance drop soon after the first win but we caught another bonus for 2.7k. The balance was dwindling pretty good but another bonus came in. Jar placements were poor and we only took in 210. It started out nice but we ended up with a 0 balance.

Round Nine – The first 100 spins went pretty quick. A double jar fruity win gave 800. One jar got up to 8x.

Round Ten – Things were looking ugly again but then we hit a big feature win and within that same win a bonus showed up. This was a nice bonus for sure. A 4th jar came into play giving us some nice multipliers. We ended up with a huge Jammin win. The total for this was 23.5k. Three spins later we got another bonus. This wasn’t as big but it did give us a 4th jar and we ended up with 5.1k. A nice follow-up bonus for sure. After spilling several K we got a huge 2 jar win for another 5k. And just like that, we got another bonus. Boom. With this bonus, we won another 13.5k which is a nice topping to the day. We had three three jar hits that exploded. This was the last round of the day and it was a good one. We made out ahead because of this.

Day Eight

Round One – We did hit a fruity win early but it wasn’t until we hit the bonus 150 spins in. We got 2.1k out of the bonus. After the bonus things went downhill fast.

Round Two – The balance was drifting until we hit a 1.5k fruity win. This went down fast.

Round Three – We had an okay bonus early. The jars just wouldn’t come together. We go 1.2k. Our balance was dropping some from the original bonus. We hit a nice bonus with two jars working together. We even got a 4th jar in play. The 4th jar started working with the 3rd jar. We collected 2.9k on this bonus. We made it to 450 spins and we went broke on this round.

Round Four – Things were hurting when we got a bonus but it didn’t pay out well for us. We only received 432. However, 10 spins later we caught another bonus. The jars were trying to come together but they just couldn’t do it. A win for 318 is all we got. This was another letdown round.

This day is one you should think about if you plan to play Jammin’ Jars.

Day Nine

Round One – A couple of fruity wins early but it went pretty flat after. We did get a 1.2k bonus many spins later. The jars were getting hit in a good way but at no point were two together which is key. We caught a second bonus on the 200th spin for 632. Hanging around at this point.

Round Two – Early in the game we had a super killer win. We had two jars working together getting up to 19x and 20x. When this happens it really shows how amazing this game can be. We walked with 43.7k. This set us up for big wins this round. We received another bonus later in the round but it only got us 546. We ended in good shape with a 39k balance.

The Final Numbers

Here is what the final numbers look like on Jammin’ Jars. We played a total of nine days and a total of 65 Rounds. Each day we played a different amount of rounds. Our starting balance was always the same each round 5000 Euros.

65 Rounds = 325,000 Euros in total deposit balances.

Total Winnings = 1,006,400 Euros.

From the stats above things look amazing. We invested 325k and pulled out 1.0 million. This gain was 675k.

Let’s think about this though. On the first day, we hit a monster round which gave us a 702k ending balance. *** Had this one round not have happened, our end result would be a loss of 27k for this case study. This is the crazy part of playing slots. We could have lost all of the rounds after the huge win and would have still been ahead by a large margin. We also think big hits do come. You’ll have to be committed for sure.

*** This was probably one of the most exciting things to watch. Even on a demo play, it was fantastic to watch these huge numbers pop on the screen. The screenshots above show some of the epic wins.

Our Nine Day Case Study Conclusion

What did we learn after playing Jammin’ Jars for nine days? Well, a lot actually. The number one thing is, plan to lose everything you bring to the table. When things are working it probably is our favorite game. If you check the stats you can see all the big wins. However, with all of those big wins, there were plenty of losses. We were definitely playing with a lot more than we should have for this case study.

The next case study will show how we would do if we reduced the bet to 10 or 20 Euros. This will keep you in the game much longer. The wins won’t be as big but the losses may not be that big either. This is something we’ll have to really test.

The game is fun and can be rewarding. You mustn’t play this game all day every day. You will learn fast that it won’t pay out the same all of the time. You have to be lucky to catch a few big bonuses. Without the bonuses showing up, your round will end poorly.

Bonus Feature – This is definitely not something that comes up a lot. You would think with a ton of dead spins the bonus would show more. This isn’t the case. You can see in the stats that sometimes we got several while other rounds we didn’t receive any. In fact, we went several rounds in a row without a bonus game.

FAQ

Is Jammin Jars Fun to Play? Without a doubt, JJ is fun to play. The dead spins can get old but when you see jars working together it’s one of the most exhilarating things to watch.

Can You Win Big on Jamming Jars? – As you can see in the second round of day one espcecially you can win super big. If things start working it will give you a huge payoff.

Does demo mode appear rigged? – Some games in demo mode do appear rigged. We feel like the Push Gaming slots try to show you real play no matter what. We’ve been told that it should play the same way but the proof is in the pudding.

What kind of Balance Should You Have? – The balance you should have should be amounts you can afford to lose. We played super high stakes with a small balance. With 5k rounds being in the 5-20 euro bets are probably best. You’ll have to make the responsible decision.
