Editor's notes
Push Gaming's breakout hit and one of the defining cluster-pays slots of its generation. Played on an 8×8 grid with no traditional reels or paylines: wins form when five or more identical symbols land adjacent to each other, and winning symbols are removed so new ones cascade in. The signature feature is the Jam Jar wild. Every jar starts with a 1x multiplier, moves one random position after each cascade, and increments its multiplier by +1 with every win it takes part in — with no upper limit. Landing three jars triggers free spins, where the jars become sticky and their multipliers persist across the entire round; this compounding is where the 20,000x maximum win lives (19,998.5x to be exact). The Rainbow feature can strike on any non-winning base game spin, dropping a giant fruit symbol to force a cluster. Jammin' Jars runs on three RTP configurations: 96.83% as the default, with 95.25% and 94.24% available to operators — a spread of 2.59 percentage points. The version in use at a given casino can be confirmed in the in-game paytable. A bonus buy option was added in October 2021 at 84x stake. Designed portrait-first for mobile, with a disco-funk fruit theme. A sequel, Jammin' Jars 2, followed in 2020 with a 50,000x ceiling.
