Jammin’ Jars 2 is an 8×8 cluster pays slot from Push Gaming with high volatility and a 50,000x maximum payout. It is one of the studio’s most popular games. Features include Wild Jars that remain on the grid and carry progressive multipliers between Cascading Wins, Instant Prize coins of up to 1,000x which pay out collectively when they land in clusters, and the Giga Jar bonus triggered by collecting Gold Vinyls. In this bonus round with huge potential, only Instant Prize symbols and Wild Jars land on the grid. This slot is available from 10p per play.

Testing Notes: Here’s What Happened When We Played Jammin’ Jars 2

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 200 spins on Jammin’ Jars 2 at Casumo Casino to test the game and this is what happened.

  • Stake Size: £1
  • Start balance: £500
  • End balance: £472.40
  • Biggest Win: 17x
  • Free Spins: 0
  • Session Time: 19 minutes 15 seconds

Despite failing to unlock the free spins or the Giga Jars round Jammin’ Jars 2 was relentlessly fun. Wild Jars dropped with regularity, every 5 to 6 spins by my count, and I accumulated a 7x progressive multiplier on one occasion. The fruit blast was a highlight, appearing 7 times and landing 17 identical top paying strawberries on one occasion. This created 3 small clusters and a 17x win. The Instant Prize feature was far more elusive, only triggering once to produce a 10x win.

The biggest win was a 17x in testing

What does all this tell us? I finished down by just under £30, on 200 spins at around 20 minutes of game time. But despite its volatility, Jammin’ Jars 2 still kicked out small, regular wins to keep me interested, and the endless cascades, wild jars, animations on the grid and jigs from the DJ and his equaliser mean Jammin Jars 2 will always be entertaining whether you are up or down. And of course, you can tell by their absence the free spins, Giga Jars and Instant Prizes, are where the epic moment really happen, because you rarely see them!

  • Wild Jars with progressive multipliers
  • Massive 50,000x top prize

What Our Reviewer Says ...

"An awesome slot with bags of personality and relentless action across the grid that delivers regular wins despite its high volatility."

Overall Score: 9.4

Theme & Design

Our Score 10

An Awesome Production That Is Endlessly Entertaining

Jammin’ Jars 2 looks and sounds as superb as the original game, bearing all the hallmarks of Push Gaming’s high level production values. The colors are sharp and vibrant, the animations slick and fun to watch, and the interweaving of theme and gameplay as exciting as ever.

Jammin’ Jars 2 – Vibrant and relentlessly fun

The best parts are the Wild Jars that bounce around accumulating multiplier values, the equalizer animation across the grid and jigging DJ as he prepares to fire massive fruit symbols in Fruit Blast, and that incessantly catchy and upbeat disco soundtrack. But there is much more too and the best way to find out is to load the game up and start playing! Jammin’ Jars 2 production is the perfect combination of visuals and soundtrack which is a big reason for the games soaring popularity.

RTP and Variance

Our Score 9

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Push Gaming have given Jammin’ Jars 2 three possible RTP settings. It’s worth checking when you open up the game to see which one your casino is running the game at. They are 96.4%, 95.35% and 90.80%. There in not much daylight between the top 2 but you want to avoid playing at 90.80%. For comparison, the original Jammin’ Jar’s has a very slightly higher optimum RTP at 96.83%.

I verified the RTP of Jammin’ Jars 2 at 4 popular slot sites. This is what I found.

  • MrQ (Independent) – 96.4% RTP
  • Casumo (independent) – 95.35% RTP
  • BacanaPlay (Skill on Net) – 95.35% RTP
  • Barz Casino (White Hat Gaming) – 95.35% RTP

It’s not unusual to find that some casino operators want to take a game at below optimum as you can see from our small sample. In truth you won’t notice the difference between 95.35% and 96.4% but to give yourself the very best chance of winning on this game I would recommend playing at MrQ where the RTP is highest.

Of course, Jammin’ Jars 2 is also a highly volatile slot with a huge win potential in the bonus round. But that makes it unpredictable and you should be wary because you can burn down your balance very quickly on slots like this.

Maximum Win

Our Score 9

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

For this sequel Push Gaming have cranked up the top payout to a phenomenal 50,000x. This is significantly higher than the original which can pay out up to 20,000x. This makes Jammin’ Jars 2 one of Push’s highest paying slots, second only to Razor Returns and on a par with games like Fire Hopper, Bison Battle and Big Bamboo.

Symbols and Paytable

Our Score 9

Jammin’ Jars 2 is a Cluster Pays slot on an 8×8 grid. Wins are formed by landing 5 or more identical symbols in positions where they are touching horizontally, vertically, or both. Whilst the paytable shows only very small wins for clusters of 5 symbols, the numbers as the clusters grow in size are huge.

And of course this game is stacked with wilds, multipliers and other modifiers that will power-up those payouts. Which is why we love it so much!

There are just 6 pay symbols. They are all brightly-colored fruits – blueberry, raspberry, plum, melon, grapefruit and strawberry. The values start at 0.1x for 5 blueberries and max out at a massive 1,000x for 32 or more strawberries.

There are also Wild Jars which help complete clusters by substituting for any other symbols and Instant Prize symbols that pay out cash prizes.

Features and Gameplay

Our Score 10

So Much Exciting Gameplay Culminating in Giga Jar Bonus Round

For me, the reason that Jammin’ Jars 2 is a joy to play is the continuous interaction of the features, starting with the Cascading Wins and moving through to the game’s climax Giga Jar round with extra Wild Jars and super-sized Instant Win symbols.

Cascading Wins And Wild Jar Multipliers

Right at the heart of this game is the Cascading Wins mechanic. It’s really simple – when clusters form, winning fruits are removed and new ones drop in to replace them. If another win is created, then the process repeats. This keeps going until no more wins are triggered. On a good run you might get 3 or 4 Cascades in a row, but it can go much further.

Wild Jars in Jammin' Jars 2
Two Wild Jars with 4x and 3x multipliers

The cool part is, if a Wild Jar forms part of a win, then it is NOT removed. Instead, once winning fruits are removed, and before the new ones drop in, our Wild Jar moves one space to an adjacent position. And each time this happens, a multiplier it carries goes up by 1x. The multiplier applies to any win the Wild Jar forms part of.

In my experience Wild Jars land roughly around one in every 5 spins, although they won’t always be part of a win. I’ve seen multiplier of up to 7x from 7 Cascades but not more, though clearly it is possible to go much higher.

Powerful Instant Prize Symbols Of Up To 1,000x

Watch out for those Instant Prize Symbols too. These have a simple stake multiplier value printed on them. When 5 or more land in a cluster their cumulative values are added together and paid out.

With a max value of 1,000x that leaves room some big, big payouts from this feature that can drop in both base game and free spins round.

Fruit Blast Adds Identical Fruits and Instant Prize Symbols

The Fruit Blast is another element of this game that I love. Both because of the super-cool animation that heralds its arrival, and the impact it can have on the grid. First, the whole grid animates like an equalizer. The reels light up in yellows and oranges. Then a Giant Fruit, and / or a Giant Instant Prize symbol will move over the board.

The Giant Fruit converts symbols on the positions it lands over into fruit symbols of the same type. The Giant Instant Prize Symbol converts  the positions it lands over into Instant Prize Symbols.

Get SIX Free Plays

The free spins round is simple. Wild Jars act as scatters and landing 3 or more on one spin earns you 6 free plays.

Like most free spins round, there are added treats. Firstly, the Wild Jar multipliers that were active when the round was triggered are carried over. And, there is no re-set between spins so those multipliers just keep growing until the round ends.

Collecting Gold Vinyl Fills The Giga Jar To Unlock The Giga Jar Feature

The absolute Holy Grail of this game, and the one that will frustrate the hell out of you as you try to unlock it, is the Giga Jar where super-sized symbols come into play.

During any spin, any Gold Vinyls that land are collected in the Giga Jar meter under the DJ to the left of the reels. When the Giga Jar meter is filled, any time a Gold Vinyl lands in future, it MAY trigger the Giga Jar feature.

First of all, ALL symbols drop off the grid. 3 or 4 Wild Jars are dropped on to the empty grid and then a 2×2, 3×3 or 4×4 Instant Prize symbol appears. Then, 8 spins play out where NO fruit symbols are in play, only Instant Prize Symbols and Wild Jars. The Wild Jars act as they do in standard play, moving between Cascades and progressing their multiplier as they do.

It doesn’t take much to figure out that the Giga Jar round has massive potential where Instant Prize symbols are landing all over the place and Wild Jar multipliers are in play.

The Final Verdict

Jammin’ Jars 2 gets one of the highest review scores we have given for good reason. This is an excellent game that both captures the fun spirit of the original and adds its own flavours through new features. Aside from the awesome production which I’ve covered in some detail already, what stood out most when playing this game was its ability to keep delivering enough in the way of wins to maintain your interest even when waiting for something bigger to happen. That is a tricky balance in a slot like this which is clearly heavily weighted towards paying out in the Giga Jar and Free Spins rounds. Without experiencing those it is still possible to see how cumulative Wild Jar multipliers and big instant win symbols are the route towards that seriously good 50,000x max win. And even if you find the volatility too much I would still recommend giving this one a spin for free anyway, to see what you might be missing!

Useful Tips When Playing Jammin’ Jars 2

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Watch Out For Gold Vinyls

Keep your eye on the grid for Gold Vinyls when they land. They will be automatically moved to the meter under the DJ. These unlock Giga Jars BUT only when the game is ready!

2. Instant Prize Symbols Can Bring Huge Wins

These can deliver a big payout out of nowhere if you are lucky. You don’t have to be in the Giga Jar feature to land a cluster of Instant Prize symbols with high values in the base game.

3. Play At Low Stakes

This is a volatile slot. In 200 spins I did not unlock the free spins or Giga Jar once. So you will need your balance to stretch to many plays to give yourself a chance. A 10p stake is a good starting point.

4. Play At Our Recommended Slot Sites

Only play at sites that are licensed in the UK. All the casinos on this page are licensed by the UK Gambling Commission which makes them safe, fair and secure.
