Jammin’ Jars slot game – Push Gaming

Some slots become memorable because of their theme; Jammin’ Jars became memorable because of what happens when several Wild jars start bouncing around the grid with growing multipliers.

Released by Push Gaming in September 2018, the game combines a colourful fruit-and-disco setting with an 8×8 cluster-pays grid, dispensing entirely with traditional pay-lines.

Winning fruit clusters disappear through cascading wins, creating space for new symbols, while Jam Jar Wilds can move around the grid and increase their multipliers whenever they contribute to another payout.

Add oversized fruit from the Rainbow Feature and a Free Spins round capable of combining several Wild multipliers, and Jammin’ Jars has considerably more depth than its simple fruit symbols suggest.

The game has a 96.83% RTP, high volatility and maximum potential of 20,000× the stake.

Where is Jammin’ Jars most popular?

Jammin’ Jars slot game is particularly relevant to UK and Irish casino players, where Push Gaming has developed a strong presence, while the game’s long-running reputation gives it broader recognition as well to German, Austrian and Swiss Casinos.

Game Features

8×8 Cluster Pays Grid

Forget about counting pay-lines in Jammin’ Jars. The game uses a large 8×8 grid, and wins form whenever 5 or more identical fruit symbols connect horizontally or vertically.

That provides considerably more screen space than a conventional 5×3 slot and is essential to the game’s cascading and Giant Fruit mechanics.

Cascading Fruit Clusters

Every successful cluster is removed from the board after its prize has been calculated. Symbols above the empty positions then fall down and fresh fruit enters the grid, potentially creating another cluster without requiring another paid spin.

Cascades continue until the new arrangement produces no further winning cluster. This mechanic becomes much more important when a Jam Jar Wild is already active because every additional cascade gives that jar another opportunity to increase its value.

Jam Jar Wilds

The dancing Jam Jars are far more than ordinary Wild symbols. When a Jar contributes to a winning combination, its multiplier increases by +1×. The Jar then moves to an adjacent position before the next symbols arrive. If another winning cluster uses the same Jar, its multiplier grows again.

A long cascade can therefore transform an initially modest Wild into a much more valuable multiplier before the sequence finally ends.

Moving Wild Multipliers

Movement is an important part of the mechanic. Rather than remaining fixed where they originally landed, Jam Jar Wilds can jump up, down, left or right after contributing to a win.

That means a Jar which helped one fruit cluster can potentially move into range of a completely different cluster during the next cascade. Its increasing multiplier travels with it.

Rainbow Feature

Jammin’ Jars can also change the scale of the symbols themselves. The Rainbow Feature introduces one or more Giant Fruit symbols onto the grid. These oversized blocks represent multiple copies of the same fruit and can therefore make forming large clusters considerably easier.

The strongest Rainbow sequences occur when Giant Fruit lands close to multiplier Jars, allowing a large cluster and an enhanced Wild to interact during the same cascade chain.

Jam Jar Free Spins

Landing enough Jam Jar symbols unlocks the game’s main bonus and awards 6 Free Spins.

The important part isn’t really the number of spins. The Jars responsible for triggering the feature are carried into the bonus, bringing their multiplier mechanic with them.

This gives the feature an immediate starting point rather than forcing players to wait for its key mechanic to appear after the bonus has already begun.

Combining Jar Multipliers

Multiple Jam Jars are where the Free Spins feature can become considerably more powerful. When several multiplier Jars contribute to the same payout, their multiplier values can combine multiplicatively rather than simply being added together.

For example, two well-developed Jars participating in the same cluster can create substantially more potential than one high multiplier working alone. This interaction between multiple moving Wilds is the central reason the bonus can reach the game’s large maximum win despite beginning with only six spins.

No Traditional Scatter Symbol

Jammin’ Jars also breaks with another slot convention. There isn’t a separate Scatter icon solely responsible for triggering the bonus. The Jam Jar itself performs multiple jobs, acting as the game’s Wild, developing multiplier and Free Spins trigger.

That keeps almost every important mechanic centred on one recognisable symbol.

RTP, Volatility and Maximum Win

Jammin’ Jars has an RTP of 96.83%, which is notably strong for a high-volatility slot of its generation. Its maximum payout reaches 20,000× the stake, while the supplied game information lists bets between €0.20 and €100 per spin.

The trade-off is its high volatility. Base-game clusters can frequently return relatively modest amounts, with much of the larger potential dependent on building multiplier Jars into useful positions.
