Symbols and Payouts

The symbols that offer payouts include blueberries, plums, apples, raspberries, oranges, and strawberries. Among these, the strawberry symbol is the most rewarding, granting a 1x payout for 5 of them, but an astonishing 100x if you manage to land 25 or more. Both the game’s wild and scatter symbols are represented by the Jam Jar symbol. This special symbol not only helps in forming additional winning combinations by substituting for other symbols but also comes with a multiplier, which we’ll explain shortly. If you land 3 or more Jam Jar symbols, it triggers the free spins option, awarding you 6 free spins to enjoy. Additionally, occasionally oversized fruit symbols, each occupying a 3×3 space, may appear during the game.

Other Jammin’ Jars Slot Features

In addition to the Bonus Buy feature, lucky players have the chance to win up to 20,000 times their bet during the spins. This incredible potential is unlocked through various game features, including the Jam Jar symbol, multiplier, cascades, rainbows, and free spins.

Wild Symbol

The game’s wild symbol, represented by the Jam Jar icon, plays a crucial role in forming winning clusters. It acts as a substitute for all other symbols, enabling players to achieve substantial victories. Additionally, it features a multiplier that starts at 1x and increases by 1 each time it contributes to a winning cluster. This multiplier is then applied to the respective winning cluster. After the Jam Jar symbol is part of a winning combination, it leaps to a random adjacent empty position on the grid. The exciting aspect is that multiple Jam Jars can land on the reels simultaneously, and if they contribute to the same winning cluster, all of their multipliers will be combined and applied.

Cascading Feature

In this slot game, there’s a cascading function, which means that when a winning cluster forms, those symbols vanish from the reels. Subsequently, fresh symbols will descend from the top of the slot. These new symbols have the potential to form additional winning clusters, and as long as new wins occur, the cascading function will persist.

Jam Jar Multipliers Feature

Keep an eye out for the Jam Jar wild symbol, as it can substitute for any symbol on the reels. After contributing to a win, the wild symbol moves to a random nearby empty spot. During a collapse or spin, all Jam Jars remain in place.

The Jam Jar Multipliers feature starts with a 1x multiplier. With each following cascade or consecutive win, the multiplier will increase by 1. There’s no maximum limit to how high the multiplier can reach.

Free Spins

When you land 3 or more Jam Jar symbols in the game, it triggers the activation of the free spins option. You’ll receive 6 free spins initially, which might seem limited at first glance. However, it’s important to note that the cascading function remains active during these free spins, and the Jam Jar symbols become sticky. This means that whether a spin results in a payout or not, all Jam Jar symbols will stay in place along with their respective multipliers. Every time they contribute to a winning cluster, they will move to an adjacent vacant position.

Rainbow Feature

While spinning the reels, you may also have the opportunity to participate in the Rainbow feature. This function activates randomly when there hasn’t been a winning combination, and it brings a magnificent rainbow that stretches across the reels. This colorful display will introduce one or more oversized symbols onto the reels, with the Giant Fruit symbols showcasing the same symbol type if multiple symbols land. It’s important to note that the Giant Fruit symbol cannot appear during the free spins round.
