    BetsRank Verdict

    Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

    Released on 14 September 2018, Jammin' Jars is one of Push Gaming's most iconic cluster pays slots and an absolute legend of the fruit/cluster genre. A neon-rainbow fruit universe with cult-classic aesthetics. An 8x8 grid, cluster pays (minimum 5 matching symbols), RTP 95.25% (versions of 92-94% are common ⚠️), high volatility, max win 20,000x (up to 2,000,000 in cash units). Signature mechanics: an avalanche function where winning clusters collapse and symbols drop from above, multiplier wilds (jars) that appear randomly and apply their multiplier to affected clusters, mega symbols (3x3) that cover a huge area, sticky wilds during free spins with cumulative multipliers, and the famous random rainbow feature (mega fruit symbols dropping from the top). Free spins are triggered by 3+ jars in the base game. No bonus buy.

    About Jammin' Jars

    Released on 14 September 2018, Jammin' Jars is one of Push Gaming's most iconic cluster pays slots and an absolute legend of the fruit/cluster genre — referenced across the industry's cluster releases (Sweet Bonanza included, to some extent). A neon-rainbow fruit universe with a late-2010s cult aesthetic. An 8x8 grid, cluster pays (minimum 5 matching symbols connected horizontally or vertically), RTP 95.25% (versions of 92-94% are common ⚠️ — checking the in-game 'i' button is essential), high volatility, max win 20,000x the stake (up to 2,000,000 in cash units). Signature mechanics: an avalanche function where winning clusters collapse and symbols drop from above (an infinite cascade as long as hits keep landing), multiplier wilds (jars) — special symbols that appear randomly and apply their multiplier to every cluster they touch, mega symbols (3x3) that cover a huge area of the grid, sticky wilds during free spins with cumulative multipliers that increment on every cascade, and the famous random rainbow feature where rainbow mega fruit symbols descend from the top of the grid. Free spins are triggered by 3+ jars landing in the base game. No bonus buy available (a 2018 slot predating Push's widespread adoption of the concept).

    Key mechanics

    • 8x8 cluster pays format (min 5 symbols)
    • Avalanche function (infinite cascade)
    • Multiplier wilds (cumulative jars)
    • Mega symbols 3x3
    • Random rainbow feature (mega fruits)
    • Sticky wilds plus cumulative multipliers (free spins)
    • Max win 20,000x

    Jammin' Jars FAQ

    What is the RTP of Jammin' Jars?

    The official RTP is 95.

    25%. ⚠️ Degraded versions of 92-94% are common depending on the casino. Checking the 'i' button in-game is essential.

    Jammin' Jars 1 or Jammin' Jars 2?

    JJ1 (2018) is the cult original: max win 20,000x, neon aesthetic, foundational mechanics.

    JJ2 (2020) is the sequel with a giga jar wild (up to x100 multiplier), max win 50,000x, identical format. Some players still prefer JJ1 for its pacing. JJ2 leans more toward big-win chasing.

    How do the multiplier jars work?

    The jars are special wilds that appear randomly on the grid.

    Each jar carries a multiplier (x2 to x100). When a winning cluster includes a jar, the multiplier applies to the win. During free spins, the jars become sticky and their multipliers accumulate.

    Is Jammin' Jars available at online casinos?

    Yes, at most online casinos that carry the Push Gaming catalogue.
