Developed by Push Gaming, Jammin’ Jars is a lovely video slot machine meant for online and mobile play. It is the result of the funkiest fantasies Push Gaming’s developers have had so far, and it’s been available since 2018.

The UK-based software studio has been operating for years, but around the time Jammin’ Jars was released, it was evident that the company was on a roll.

Jammin’ Jars will make you jam to the sounds of irresistible disco tunes and then make you stuff yourself with delicious fruit to make up for all the lost calories.

It is a very fun slot to play, and it comes complete with potentially big payouts, innovative features and polished graphics.

On the very mention of fruit, we all immediately think about old school slots with plums and cherries and 3 reels. Jammin’ Jars took this traditional motif and made something impressive out of it. First of all, this slot may very well feature more fruit than your local farmers’ market.

The name of the game is wordplay, one that should get us in the mood for jam and jammin’, aka enjoying music and dancing. A perfect match, really – a combo to make you feel the sweetness and warmth both on the inside and on the outside.

As you start up the game you will be stepping on the dance floor. The music is groovy and very easy on the ears, while the colours are bright. The giant disco ball throws rays of light all over, making different colours come to life on every single beat. Then you have a huge grid of all sorts of fruit stepping onto the scene, and you know the time has come to make some jam.

Before the funky fever gets the best of you, we recommend looking at the paytable real quick, just to find out which pieces of fruit will make the best jam. On the high-value scale, you will see strawberries, oranges and raspberries.

Apples, plums and blueberries aren’t as rewarding, but they are equally delicious! There is only one special symbol in the Jammin’ Jar slot, and that’s a multi-coloured jam jar which plays the role of a specific Wild symbol, as well as the role of Scatter.

Structure-wise, Jammin’ Jars adopts a distinct 8×8 set of reels. Highly unusual, and even more so when you find out that there are no regular paying lines in this game either. Instead, winnings are achieved by forming clusters of matching symbols. The more symbols you get in a cluster (they must touch vertically and/or horizontally), the bigger the payout.

A minimum of 5 identical symbols is needed to claim a payout according to the paytable, but it is possible to form huge clusters of 25+ symbols, and for that achievement the players will get the highest payout, as far as the base game goes, that is.

What happens when a cluster is formed? Well, the matching icons collapse and new symbols fall down to their places. This means that you can potentially win more than one payout on a single spin.

Gameplay is easy. Select your bet and press the Spin button. To play a number of games successively, you can press the Autoplay button. If you wish to skip some of the animation sequences you can make us of the Quick Play and Turbo Play buttons.

Jammin’ Jars starts off with modest payouts. It requires a bit of patience, but with the jam jars appear the party begins. Push Gaming’s funkadelic slot is available across all device, so it won’t make a difference whether you play it on a handheld device or your home computer.

The Free Spins

The Wild in Jammin’ Jars acts differently when compared to any regular slot Wild. It substitutes for the missing symbols in a winning combo, in this case cluster, but it won’t disappear. Instead, it moves to an adjacent position prior to the next set of symbols collapsing. The jam jar Wilds come with increasing multipliers – they increase by 1x every time they form part of a winning cluster.

The jam jar becomes the Scatter when three or more of them land on the same spin. This distribution triggers the Free Games feature. The players receives 6 free plays for 3 Scatters and the jam jars remain in their positions throughout the round, acting as Wilds again, providing better chances of winning and adding the multipliers to the final winning score of the bonus.

The Rainbow Bonus

Apart from the Free Games, Jammin’ Jars features a random Rainbow bonus that can occur on any non-winning spin. It manifests as a rainbow, a curtain of colour, if you will, covering the entire grid. Once it pulls up one massive 3×3 fruit will stick to the reels and help form winning combos.

The special features are lucrative, but they don’t show up as often as one would like. The wins happen rather sporadically and there’s not much you can do about it except enjoy the funky background music and observe the bright colours.

If you’re not into disco and the groovy vibes are not your thing, the soundtrack may become a bit annoying after a while. However, the game allows you to pull the plug on the music. The variance is somewhere in the medium to high range, and the RTP is relatively high at 96.83%

All things considered, Jammin’ Jars is not a complicated game. It has many things going for it, from moving Wilds and multipliers to collapsing reels, mega symbols and free spins. On the other hand, to create wins worth your while, you are dependent on the jam jar symbols and multipliers most of the time.

Jammin’ Jars may lack some refinement for a grid-based game – you may see a better job done with NetEnt’s Emoji Planet.

When it comes to the aspect of collapsing reels, no slot has done it better than the cult classic Gonzo’s Quest. Jammin’ Jars is well produced and can be immensely enjoyable, to the right type of player.
