Jammin’ Jars is an 8×8 cluster-pays video slot from Push Gaming, built around a disco-fruit theme and a colourful jar-jamming mascot band instead of traditional reels and paylines. Released in September 2018, it carries a 96.83% RTP, high volatility, and a maximum win of roughly 20,000× the stake, and it’s widely regarded as the game that put Push Gaming on the map as a top-tier slot studio rather than a niche developer.
Jammin’ Jars isn’t available for real-money play at either of our linked casinos (Sloto Cash or Fair Go, both RTG-powered) — Push Gaming is a UK/Malta-regulated studio and doesn’t license its titles to RTG-style offshore casinos. Try Sloto Cash instead for a working real-money slots option, or play Jammin’ Jars in demo mode on Push Gaming’s own site.

Push Gaming released Jammin’ Jars in September 2018, at a point when most of the market’s cluster-pays slots were still built on 6×6 or smaller grids borrowed from earlier developers. Jammin’ Jars broke from that mould with a wide 8×8 layout and a genuinely original visual identity — a live disco band of anthropomorphic fruit jars — rather than a generic fruit-machine skin. The game became Push Gaming’s breakout hit, repeatedly cited by industry outlets as the release that shifted the studio from a smaller regulated-market supplier into one operators actively sought out, and it directly led to the 2021 sequel, Jammin’ Jars 2.
Wins land whenever 5 or more matching symbols connect horizontally or vertically anywhere on the 8×8 grid; winning clusters then explode and cascade, dropping new symbols into the empty spaces for a chance at further wins in the same spin without any extra bet. Landing eight or more Jam Jar wild symbols anywhere on the grid triggers the Free Spins round — 8 spins in which every wild that lands sticks in place for the rest of the round, and the multiplier attached to each wild climbs every time it takes part in another win, letting the board fill with high-value stuck wilds as the round progresses. The base game also runs an Extra Wilds feature that periodically seeds one or two random wilds onto the grid before a spin resolves, adding extra cascade potential even outside the bonus.
Pros
- Wide 8×8 cluster-pays grid was genuinely novel when released and still stands out from reel-based slots
- Sticky, climbing-multiplier wilds during Free Spins can turn a strong bonus round into a very large single win
- 96.83% RTP is above the online-slot average and has stayed consistent across the game’s life
- Extra Wilds feature adds cascade potential to ordinary base-game spins, not just the bonus round
- Distinctive disco/fruit visual theme and soundtrack that Push Gaming has never simply reused elsewhere
Cons
- High volatility means long stretches between meaningful wins outside the bonus round
- Eight-symbol wild trigger for Free Spins can feel rare during ordinary play sessions
- No traditional paylines display, which can be a harder read for players used to classic reel slots
- 20,000× max win, while strong, has been surpassed by Push Gaming’s own later titles (Jammin’ Jars 2 doubles it)
