How does the Giant Jar feature work?

Giant Jar is a 2x2 wild super-symbol that lands on the 8x8 grid and carries an escalating multiplier — starts at x1 and increments by x1 with every cascade the Jar participates in. Multiple Giant Jars active simultaneously produce Jammin Jars' biggest wins.

How are free spins triggered?

Three Jam Jar scatters anywhere on the grid trigger 6 free spins. During the feature, Giant Jar wilds have their multipliers preserved between spins rather than resetting — the core mechanic that produces max-win outcomes.

Jammin Jars pokie by Push Gaming — 8x8 fruit cluster grid with Giant Jar wilds

Jammin Jars is the pokie Push Gaming released in 2018 that put the small London studio on the map. An 8×8 cluster-pay grid, a funk-disco soundtrack with moving jam jars that dance across the reels, and one mechanic that does most of the heavy lifting: the Giant Jar wild. It's a 2×2 super-symbol that lands on the grid and carries a multiplier that starts at 1× and increments by 1× every time the Jar participates in a winning cascade. Three cascades in, it's multiplying wins by 3×. Ten cascades in, it's at 10×. During free spins, multipliers persist between spins rather than resetting — which is how players documented pushing Giant Jars to 20×, 30×, occasionally 50× multipliers over extended feature sessions and producing the pokie's published 20,000× max-win outcomes.

The success of Jammin Jars has kept Push Gaming relevant in a market increasingly dominated by Pragmatic Play and Play'n GO. Jammin Jars 2 arrived in 2020 with updated mechanics but similar structure; Fat Banker and Fat Rabbit borrow the Giant Jar template under new themes. The 96.83% RTP is competitive, and the 8×8 grid format produces engaging sessions because the larger grid means more cluster formations and more cascade chains per spin than traditional 6×5 or 7×7 layouts.

At a glance

Large 8×8 cluster grid with Giant Jar wilds as the defining mechanic. Escalating multipliers during free spins — persisting between spins rather than resetting — drive the pokie's biggest outcomes. Unusual high 96.83% RTP. Strong theme execution with distinctive dancing-jar character art.

How Jammin Jars plays

Eight columns, eight rows, no paylines. Matches form on groups of 5 or more identical fruit symbols connected horizontally or vertically. After a cluster pays, those symbols disappear and new fruits cascade down to fill the gaps — potentially chaining further cluster matches from a single spin.

The paytable leads with strawberry and grape (highest), followed by orange, plum, lemon, pear and raspberry across seven fruit symbols. No low-paying royals. Bet range runs A$0.20 to A$100 per spin.

Bonus features

Cluster pays (5+ matches) — groups of 5 or more matching fruits connected horizontally or vertically trigger payouts.
Cascading wins — winning clusters clear; new fruits cascade down to fill gaps, potentially chaining additional wins from a single initial spin.
Giant Jar wild (2×2 super-symbol) — the headline mechanic. A 2×2 wild symbol that substitutes for all fruits and carries a multiplier. The multiplier starts at 1× and increments by 1× every cascade the Jar participates in. Multiple Giant Jars can appear on the grid simultaneously.
Dancing Jar movement — Giant Jars don't stay still between cascades. They move one position on the grid after each cascade, creating fresh cluster opportunities at new positions.
Free Spins (3 scatters) — 6 free spins. Giant Jar multipliers persist between spins rather than resetting, unlike base-game behaviour. This is where extended feature sessions produce max-win outcomes.
No bonus buy on standard build — Jammin Jars doesn't include a direct feature purchase option on most AU-facing casino builds.

Theme, graphics and sound

Psychedelic disco palette — pinks, purples, neon greens, yellow-orange flickers. The Giant Jar characters have faces; they dance between cascades with distinct animated personalities. Background is a checkered disco dance floor. Sound design is one of the most recognisable in the pokies world — a 70s-funk-disco track with prominent bass, electric piano, and horn sections that swells dramatically during feature triggers and Giant Jar multiplier bumps. The whole audiovisual package is a committed, full-intensity experience.

Mobile play

Push Gaming's HTML5 build is well-optimised. The 8×8 grid is surprisingly readable on phones in both portrait and landscape — the larger grid footprint is offset by minimal UI chrome. Giant Jar multiplier indicators are always visible. Dance animations add character without obscuring the grid state. Autoplay is standard.

FAQ

What is the RTP of Jammin Jars?

96.83% on Push Gaming's standard build — one of the higher figures in the cluster-pay category.

How high can Giant Jar multipliers climb?

No published hard cap. Multipliers increment by 1× per cascade the Jar participates in, with no upper bound. Documented player sessions have reached 50×+ multipliers on individual Jars during extended free spin rounds, though these are exceptional outcomes.

Why do the Giant Jars move?

Jammin Jars' signature mechanic — each cascade shifts Giant Jars to adjacent grid positions. Creates fresh cluster formation opportunities; prevents the Jars from sitting in dead positions. Mechanically distinct from static wild symbols.

Is Jammin Jars worth playing over Sweet Bonanza?

Different designs for different preferences. Sweet Bonanza has higher max-win ceiling (21,100× vs 20,000×) and bonus-buy availability. Jammin Jars has persistent feature multipliers and larger grid footprint. Both are high-volatility; match theme preference to your choice.
