Jammin' Jars is a 2018 Push Gaming fruit slot played on an 8x8 cluster pays grid. Jam jar wilds move across the reels and build multipliers, and free spins make them sticky with multipliers that never reset. A Rainbow feature can drop a giant fruit symbol after a losing spin. The maximum win is about 20,000x. It suits you if you want a colourful cluster game with real upside.
How does Jammin' Jars work?
Clusters of five or more matching fruits connected horizontally or vertically pay out. Winning symbols disappear and new ones drop in, so a single spin can chain several wins.
Jam jar wilds substitute for fruits. Each time a jar is part of a win, its multiplier increases by one. After a losing spin, the Rainbow feature can trigger and drop a 3x3 giant fruit symbol, with matching fruits next to it joining its cluster.
Stakes run from 0.20 to 100 per spin, though some casinos cap the maximum lower. The 8x8 grid is large, so cascades often continue for several steps before a spin ends.
What are the Jammin' Jars bonus features?
Landing three or more jam jars on one spin triggers six free spins. The jars that triggered the round stay on the grid and become sticky.
In free spins the jars move around the grid, and their multipliers keep rising without resetting for the rest of the round. New jars that land during the feature also stick, adding to the multipliers in play. Since 2021 there is an optional bonus buy at 84x your stake outside the UK.
Is Jammin' Jars worth playing? RTP and volatility explained
The highest RTP is 96.83%. Push Gaming also offers 95.25% and 94.24% versions, so check the game rules at your casino before you play.
Volatility is high. The base game gives frequent small cluster wins, while the big outcomes depend on several jars with high multipliers combining in free spins.
An RTP of 96.83% is a long-run average measured over millions of spins. In theory about 96.83 units come back for every 100 wagered, but a single session can end far above or below that. Volatility describes how those returns are spread out, and at high volatility you should expect fewer wins, longer losing runs and a bigger share of the return concentrated in rare large hits.
Tips before you play Jammin' Jars
- Look for the 96.83% version in the paytable.
- Free spins with several jars carry most of the value, so do not judge the game on a short base game run.
- If you buy the bonus, its RTP is slightly lower than the base game at about 96.49%.
- Set a deposit or loss limit in your casino account before you start, and stop when you reach it.
