Jammin Jars

Jammin Jars

Samuel Read Last Updated 2021-07-05

The disco inferno has spread to the online slot sector in Jammin’ Jars, the latest release from Push Gaming.

This massive slot, played on a 9x9 reel, is more or less unbeatable: there are collapse and cascade features active on every win, leading to potentially endless free re-spins, as well as free spins, win multipliers without limit, and more. Phenomenal RTP helps its case further.


As the disco ball twirls over the glamorous nightclub background, fruits and berries galore appear on the reels. As is only appropriate, and joyful, electric guitar-rich soundtrack will encourage players to move their hips as well as the reels.

Gaming symbols include strawberries, oranges, raspberries, apples, grapes, and blueberries. A jam jar acts as wild, helping to form winning combinations while also adding increasing win multipliers. It also acts as scatter.

Betting Options and Functions

Jammin’ Jars may have a retro ambience, but the game design is as modern as can be. Instead of traditional paylines, wins are awarded whenever 5 or more of the same gaming symbol are connected horizontally or vertically on the reels.

Total per-spin bet is set simply from 0.20–100.00 times the betting currency. Autospins are available for up to 100 spins at a time, with optional stops built in for adjustable total loss or single win limits. Payable information, sound options, and detailed game rules are available on separate screens. 

As of 1st July 2021, the developer offers three different RTP values for this game - 96.83%, 95.25% and 90.45%. This ensures more flexibility for players and operators alike, and players will be aware of the RTP in play from the game loading screen


With the collapsing wins leading to so many free re-spins, the design team could have released Jam Jars at is, without adding any bonuses. Nevertheless, they went the extra mile, ensuring that players can enjoy a truly remarkable gaming experience.

First of all, the jam jar symbols have special properties even beyond acting as wild and scatter: after contributing to a win, they move to an adjacent position before collapse occurs. They remain on the reels for an any all additional collapses and cascades, disappearing only after a non-winning spin. What’s more, every time they are involved in a win, their win multiplier increases by one (from a starting win multiplier of 1x). This win multiplier can increase without limit, and is applied to every win in which they are involved.

The Free Games Feature begins whenever three or more jam jars appear anywhere on the reels. The jam jar symbols remain on the reels throughout the feature, while their multipliers increase with each win in which they are involved. Six or more free spins will be awarded.

There is also a Rainbow Feature, which takes the sting out of non-winning spins. It occurs at random, bringing a 3x3 super symbol to the reels, triggering a win and a collapse (which may, in turn, trigger additional wins).

Our Take

Jammin’ Jars is simply above approach: this is by far Push Gaming’s best offering yet. There are a unique gaming structure, seemingly endless bonus features, and some of the highest RTP available anywhere.

Fans of musical-themed slots might enjoy Turn It Up, a hard rock-themed slot from this same designer.
