    BetsRank Verdict

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

    The sequel fixes the original's real flaw: Jammin' Jars sits at 95.25% in the BetsRank database against 96.40% here. A full point of RTP is a lot, and on its own it almost justifies the follow-up.

    The rest is more arguable. Six free spins is a joke — Push Gaming half admits it, conceding that nothing special happens beyond the three wild jars staying put. The actual content is the Giga Jar, and it sits behind a gold vinyl meter you have to fill out of your own bankroll. The tier system is murkier still: SlotCatalog states the RTP starts at 96.10% and only climbs to 96.60% after thirty-five vinyls are collected. In other words, the number the studio publishes, 96.40%, describes a player already well into the progression. Someone opening the game for the first time is starting below it.

    It remains an excellent cluster game with the best wild jar mechanic on the market and a 50,000x ceiling, but I would rather a studio hand you its RTP at the door than make you work for it.

    Strengths

    • +96.40% official against 95.25% for the first Jammin' Jars on BetsRank
    • +The compounding wild jar multiplier is still the best mechanic of its kind
    • +50,000x highest observed win, more than double the original
    • +No bonus buy offered anywhere
    • +Fruit Blast can trigger on any win, with no entry condition

    To consider

    • Six free spins, with no additional mechanic layered on
    • The real feature, Giga Jar, is locked behind a meter you have to grind
    • Per SlotCatalog the RTP opens at 96.10%, below the official 96.40%
    • A minimum cluster pays 1.5x at best and 0.1x at worst: most wins do not cover the spin
    • A wild jar outside a cluster is purely decorative

    About Jammin' Jars 2

    Jammin' Jars 2 runs on an 8x8 grid, 64 positions, with no paylines at all: you need at least five matching adjacent fruits to form a paying cluster. Five out of sixty-four is a low bar, and the paytable reflects that brutally — a minimum cluster of the best fruit pays 1.5x your stake, the weakest one 0.1x. Put plainly, the large majority of wins in this game do not even cover the spin that produced them. The real money starts past thirty-two symbols, where the top fruit jumps to 1,000x and the lowest to 100x.

    The wild jar is the centrepiece. Landing it is not enough: it has to be part of a winning cluster before it comes alive. It then moves to an adjacent empty position and, on every move, its multiplier gains a point. As long as new cascades keep triggering, it keeps hopping and growing. That compounding is why a single sequence can be worth thousands of times the stake while the paytable looks so thin. The flip side is blunt: a jar that lands outside any cluster does absolutely nothing.

    Instant prizes land in blue tiles. They do not pay on their own: you need five adjacent ones, which turn purple and form a paying cluster. Push Gaming advertises values up to 1,000x; Clash of Slots notes that the everyday range sits between 1x and 50x, with the top value staying rare.

    Fruit Blast can fire on any win. An equaliser covers the grid and the DJ shoots one to three volleys of giant fruit that burst into clusters. The smallest format is a 2x2, which still needs a neighbouring symbol to complete the cluster; from 3x3 upwards a win is guaranteed.

    Three or more wild jars award six free spins. Six is not a typo. The three jars stay on screen for the whole round and keep moving and growing, but the studio adds nothing else on top.

    The feature that matters sits elsewhere: the Giga Jar. You collect gold vinyls that fill a meter, and at the maximum level the feature can trigger. It awards 8 Giga Spins with nothing but coin symbols on the grid, three wild jars to start and a Giga Jar block landing as a 2x2, or a paying 3x3 or 4x4. When a wild jar multiplier lands next to a paying cluster, its value is added to the win. Some prize symbols carry one or two extra spins. When it ends, a fresh Giga Jar appears, boosted to level 2, 3 or 4.

    That same meter also drives the RTP, and this is the single most important line on the page. Push Gaming publishes 96.40% — £3.60 of theoretical house margin per £100 staked. SlotCatalog spells out a progression instead: 96.10% at the start, 96.2% at twenty vinyls, 96.3% at twenty-five, 96.4% at thirty and 96.6% at thirty-five. Clash of Slots confirms a 0.50 point gap between the opening level and the maximum. Both sources therefore contradict the official page, which shows a single figure. At minimum, know that you do not start at the advertised number.

    There is no bonus buy, which fits a game built on progression. Stakes run from £0.10 to £100, and the highest observed win of 50,000x works out at £5,000 at 10p, £50,000 at £1 and £5,000,000 at the maximum stake. Released on 2 June 2021.

    Jammin' Jars 2 FAQ

    What is the real RTP of Jammin' Jars 2?

    Push Gaming publishes 96.

    40%, meaning the house keeps £3. 60 per £100 staked. SlotCatalog describes a progression tied to gold vinyls, though: 96. 10% at the start, then 96. 2%, 96. 3%, 96. 4% and 96. 6% at the maximum level.

    Why does the RTP change mid-session?

    The gold vinyl meter climbs through levels, and each level lifts the theoretical return slightly.

    Clash of Slots reports a 0. 50 point gap between the opening level and the maximum. You therefore begin below the number the studio advertises.

    How does the wild jar work?

    It has to be part of a winning cluster before it activates.

    It then moves to an adjacent empty position and gains a multiplier point on each move, for as long as new cascades keep chaining. Outside a cluster it does nothing at all.

    How many free spins does the main bonus give?

    Three or more wild jars award six free spins, and nothing more: the three jars simply stay on screen for the whole round, still moving and still growing.

    It is the most disappointing feature in the game.

    What is the Giga Jar and how do you reach it?

    It is the game's real feature: 8 spins with only coin symbols, three wild jars to start and a Giga Jar block at 2x2, 3x3 or 4x4.

    It can only trigger once the gold vinyl meter has reached its maximum level.

    How do instant prizes pay?

    They land in blue tiles and do not pay on their own: you need five adjacent tiles, which turn purple and form a cluster.

    Push Gaming advertises up to 1,000x; Clash of Slots puts the everyday range between 1x and 50x.

    What is Fruit Blast?

    Any win can trigger it.

    An equaliser covers the grid and the DJ fires one to three volleys of giant fruit. The smallest format, a 2x2, still needs a neighbouring symbol to complete a cluster; from 3x3 upwards the win is guaranteed.

    Does Jammin' Jars 2 have a bonus buy?

    No.

    Neither Push Gaming's official page nor Clash of Slots lists one, and the game is built on cumulative progression that a purchase would make nonsense of. It is also one less restriction in markets that ban the option.

    What is 50,000x worth in real money?

    At the 10p minimum, £5,000.

    At £1, £50,000. At the £100 maximum, £5,000,000. This is the highest win Push Gaming has observed, not a ceiling the game reaches with any regularity.

    Should you play the first or the second Jammin' Jars?

    On the numbers the sequel wins comfortably: 96.

    40% against 95. 25% on BetsRank, and 50,000x against 20,000x. The original stays more direct, with no progression meter and no feature locked behind a collection target.

    Why do small clusters pay so little?

    A five-symbol cluster returns 1.

    5x for the best fruit and 0. 1x for the weakest. The table is built so the value comes from large clusters past thirty-two symbols, and above all from the wild jar's compounding multiplier.
