Jammin’ Jars Slot Details & Wager Limits

The Jammin’ Jars slot takes place on an 8x8 grid and uses a Cluster Pays mechanic. To form a win, you need to land a cluster of 5 or more matching symbols to create a winner. A cluster is defined as 5 or more matching symbols touching vertically and/or horizontally.

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.

You can play Jammin’ Jars from 20p to £100 per spin which caters to all bankrolls. There is an Autoplay function (located next to the main spin button) where you can choose from 10 to 100 spins. You also have the option to set a loss limit (up to 100 x stake) or a single win limit (again up to 100 x stake). In the Settings area, you can opt for the Turbo Mode function as well as remove all sounds, music and sound effects.

Jammin’ Jars is a very high variance slot. With great risk, there’s normally great rewards. That’s certainly the case here as you can win up to 20,000 x your stake on each spin.
