Jammin' Jars Slot

Charming in concept, Jammin’ Jars is a 8 rows x 8 reels slot with cascading reels. The game is bursting with brightly colored fruits and jam jars. In addition, Jammin’ Jars promises bunches of fun with its exciting bonus features. Whether you are looking to play for fun or get the opportunity to win big, this slot is a perfectly blended cocktail of slot flavors.


There are 6 different symbols in the Jammin’ Jars online slot: blueberries, apples, raspberries, oranges, strawberries, and plums. To generate a payout, a cluster of 5 or more matching symbols must land next to one another. Each of these colorful symbols has its own value. The blueberry is the least valuable, and it will pay out 0.1 times your initial stake. The strawberry, on the other hand, will pay up to 100 times your original stake if you have up to 25 of these on the reels. As we already mentioned, Jammin’ Jars doesn’t have regular paylines but a Cluster Pays mechanics, which lets you win in groups of symbols.

The cascading reels engine is another nice diversion from traditional gameplay as it means that winning symbols disappear from the game screen so that new symbols can appear and form winning combinations.

Special Features

The Jam Jar symbol is the Wild that can appear anywhere on the reels and substitute for any fruit symbol in a cluster. What’s more, these Jam Jars also come with built-in multipliers. So for each subsequent win, Jam Jars contribute an additional x1 multiplier to the winning combination. The Jam Jar is also a Scatter and if you land 3 or more on the reels during the same spin, it will trigger the Free Spin feature.

The Jammin’ Jars Rainbow feature is yet another brilliant add-on as it can be randomly triggered after a non-winning spin. A rainbow will drop past the reels, leaving a Giant Symbol on the screen. This Giant Symbol will convert all symbols on the positions it covers into matching symbols, which will maximize your winning potential.

Free Spins

Free spins in Jammin’ Jars can be earned by landing at least three Jam Jar wilds on a single spin. As soon as the free spins round has been triggered, six free spins will be awarded to you. In this free spins game, multipliers can only go up making big wins a definite possibility. The value of the multiplier, which can be carried over from the base game and remains sticky throughout, increases with every cascade. New wild symbols that land on the reels during the free spins will also be sticky.


Jammin’ Jars is all about multiplier wilds. And, what’s more, these can come with unlimited growth potential. They can increase by 1x each time they are part of a winning combo and only drop off the reels when no more win is made. Landing three Jam Jar wilds is enough to activate this feature where the multipliers increase with every cascade.

Rainbow Feature

Just because you don’t win on every spin doesn’t always matter with this slot. As mentioned above, that’s because the game has a randomly triggered Rainbow Feature that can activate after any non paying spin during the base game. When it does, a colorful rainbow will shine out over the board and add a minimum of one giant fruit symbol to the board. Any positions on the grid - other than the Jam Jars that is – that are occupied by the giant fruit symbol will transform to match it. Matching symbols then become part of the winning cluster.
