Jammin’ Jars is a 2018 online slot from the British studio Push Gaming. It is a fruit-themed game, but it does not use reels and lines in the usual way. It is played on a large grid, and you win by landing groups of matching fruit that touch each other.
The demo on this page is the original Jammin’ Jars. The star of the game is the jam jar, a wild that stays on the grid, moves around and builds up a multiplier as it takes part in wins. You can try it here with free practice credits.

How Jammin' Jars Works
The grid is 8 symbols wide and 8 high. There are no paylines. You win when 5 or more of the same fruit sit in a cluster, touching side to side or top to bottom. The bigger the cluster, the bigger the prize. Bets run from 0.20 to 100 credits per spin.
After a win, the winning fruit disappear and the symbols above drop down to fill the gaps, with new ones falling in from the top. If that makes a new cluster, it pays too, and the process repeats. One paid spin can therefore produce a chain of several wins in a row.
The jam jar is the wild and stands in for any fruit. When a jar is part of a win it does not disappear. It stays on the grid, shifts to a nearby position, and its multiplier goes up. A jar that keeps landing in wins can build a large multiplier within a single spin.
Jammin' Jars Bonus Features
Jam Jar wilds
Jars substitute for all fruit symbols. Each time a jar is part of a winning cluster it stays on the grid, moves to a nearby spot and its multiplier grows. That multiplier applies to any later cluster the jar joins.
Collapsing wins
Winning clusters are removed and the remaining symbols fall down, with new ones dropping in from above. New clusters formed this way pay as well, and the collapses continue until no new win appears.
Rainbow Feature
This can trigger at random after a spin with no win. A rainbow crosses the grid and adds one or more giant fruit symbols, which are large blocks of a single fruit that make a cluster win likely.
Free Games
Three or more jam jars on the grid in the same spin award 6 free spins. The jars stay on the grid for the whole round, and their multipliers do not reset between spins, so they can climb much higher than in the main game.
More Jammin' Jars Versions to Play Free
Jammin’ Jars 2, released in 2021, keeps the 8×8 grid, the clusters and the jam jars and adds a good deal on top. It has a Giga Jar feature, a random Fruit Blast that fires giant fruit onto the grid, and gold vinyl records to collect that unlock a Giga Spins bonus round. Its listed top win is higher, at 50,000 times the bet.

- There are no lines to learn. Any five matching fruit that touch, in any shape, count as a win.
- The listed top win is 20,000 times the bet, and it would come from the free games, where jar multipliers carry over from spin to spin.
