Jammin’ Jars Slot Details & Wager Limits

Reels/Paylines: 8×8 Grid, Cluster Pays

Stakes Range: 20p to £100 per spin

Max Win: 20,000 x stake per spin

The Jammin’ Jars slot takes place on an 8×8 grid and uses a Cluster Pays mechanic. To form a win, you need to land a cluster of 5 or more matching symbols to create a winner. A cluster is defined as 5 or more matching symbols touching vertically and/or horizontally.

After a winning spin, the successful symbols are removed from play and new ones drop in and replace them. A new payout calculation is then made. The collapses continue as long as a new winning combination is created. Helping to create them is the jam jar symbol which is the wild.

If the wild forms part of a winning cluster, it moves to an adjacent position prior to the next symbol collapse. All jam jars on display are held in place when a collapse occurs. The jam jar wilds also come with multipliers. These increase by 1x every time they form part of a winning combination. They drop off the reels when no new winner is landed.

You can play Jammin’ Jars from 20p to £100 per spin which caters to all bankrolls. There is an Autoplay function (located next to the main spin button) where you can choose from 10 to 100 spins. You also have the option to set a loss limit (up to 100 x stake) or a single win limit (again up to 100 x stake). In the Settings area, you can opt for the Turbo Mode function as well as remove all sounds, music and sound effects.

Jammin’ Jars is a very high variance slot. With great risk, there’s normally great rewards. That’s certainly the case here as you can win up to 20,000 x your stake on each spin.

In order of value are blueberries, plums, apples, raspberries, oranges and strawberries. You need to land a cluster of 5 or more matching symbols to create a winner. With 25 of each symbol possible, the highest value symbol is the strawberry. Here’s what each symbol pays for 25 or more:

Jammin’ Jars Bonus Features

The Jammin’ Jars slot game benefits from 4 bonus features. You have the randomly activated Rainbow feature where 1 or more giant fruit symbols land to give you a win. The Jam Jar wilds come with multipliers which increase with each win/cascade. If you land 3 of them on the reels, you’ll play the Free Games feature where the multipliers can increase with every collapse.

Rainbow feature

jammin-jars-slot-rainbow-feature

You have the Rainbow feature which can become active following any winless spin. A rainbow drops down onto the reels and delivers a colossal fruit symbol. Any matching symbols adjacent to this colossal symbol also become part of the winning cluster.

Jam Jar Multipliers feature

jammin-jars-slot-jam-jar-multipliers-feature

Lookout for the Jam Jar wild symbol which replaces all symbols. When part of a win, the wild shifts to a random adjacent and vacant position. When a collapse/spin occurs, all Jam Jars are held in position.

Known the Jam Jar Multipliers feature the multiplier begins at 1x. Every subsequent cascade or consecutive win will see the multiplier increase by 1. There’s no limit to how high the multiplier can go.

Free Games feature

Jammin' Jars slot - Free Games feature

Land 3 or more jam jar wilds on the same spin and you’ll trigger the Free Games feature. Here you’ll receive 6 free spins with the possibility of the multiplier increasing with each collapse.

If you had any multipliers in the base game, they are carried over. What makes the free spins stand out is that the multipliers can only increase meaning bigger wins are possible.

Bonus Buy feature

As of October 2021, Push Gaming have introduced a Bonus Buy feature. This allows you to buy your way into the free spins. Look out for the Star icon to use it. 3 or 4 jam jar wilds will set you back 100 or 200 x stake respectively. This option isn’t available in the UK though due to regulations.

The Jammin’ Jars slot is a relatively simple game. The design is glossy and brash and there’s bouncy backing track playing as you spin. The gameplay is just as straightforward as the design. What you make of Jammin’ Jars will come down to your thoughts on collapsing reels slots.

That said, there’s not much in the way of variety but it’s the simplicity, big win potential and high RTP which makes Jammin’ Jars such a lethal fruit cocktail. It’s an all or nothing slot game though so you need patience and luck.

As a result, Jammin Jars’ has achieved cult status and is played regular by slot streamers in the hope of landing the big possible payouts. One of the most popular free play slots in the UK, it’s played just as much today as when it was first released.

Due to it’s success, Push Gaming released the Jammin’ Jars 2 slot. With a lower RTP of 96.4%, it comes with more bonus features and bigger max wins of 50,000 x bet.
