Jammin’ Jars is a simple, colourful, collapsing reels slot from Push Gaming. Played using an 8 reel, 8 row game engine, winning combinations are created by landing clusters of 5 or more matching symbols. Look out for giant symbols that can drop onto the reels at random and wilds that can increase multipliers. There’s also a free spins round. Play on all devices from between 20p and £100 per spin.

The design in Jammin’ Jars is bright and bold. On the 8×8 grid you’ll see 6 different fruity symbols. In order of value are blueberries, plums, apples, raspberries, oranges and strawberries. You need to land a cluster of 5 or more matching symbols to create a winner. Payouts start at 0.1 times your total stake if you land 5 of the lowest value blueberry. They can reach 100 times your total stake if you manage to find 25 or more of the strawberry in combination.

After a winning spin, the successful symbols are removed from play and new ones drop in and replace them. A new payout calculation is then made. The collapses continue as long as a new winning combination is created. Helping to create them is the jam jar symbol which is the wild.

If the wild forms part of a winning cluster, it moves to an adjacent position prior to the next symbol collapse. All jam jars on display are held in place when a collapse occurs. The jam jar wilds also come with multipliers. These increase by 1x every time they form part of a winning combination. They drop off the reels when no new winner is landed.

Land 3 or more jam jar wilds on the same spin and you’ll trigger the Free Games feature – here you get a random number of free spins with the possibility of the multiplier increasing with each collapse.

The other extra is the Rainbow feature which can become active following any winless spin. A rainbow drops down onto the reels and delivers a colossal fruit symbol. Any matching symbols adjacent to this colossal symbol also become part of the winning cluster.

Jammin’ Jars is a very simple game. The design is glossy and brash and there’s bouncy backing track playing as you spin. The gameplay is just as straightforward as the design. What you make of Jammin’ Jars will come down to your thoughts on collapsing reels slots.

There’s not much in the way of variety but if you enjoy the steady stream of action that the symbol drops can deliver then Jammin’ Jars should tickle your fancy. If you like cascading wins, I suggest you try NetEnt’s Gonzo’s Quest which offers multipliers of up to 15x in the feature.
