Bonus Features in Jammin' Jars

The Jammin’ Jars slot game benefits from 3 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

There is 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

Lookout for the Jam Jar wild symbol which replaces all symbols. When part of a win, the symbol shifts to a random adjacent and vacant position. When a collapse/spin occurs, all Jam Jars are held in position.  Beginning with a 1x multiplier, 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 featureLand 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.

Jammin’ Jars Slot Details & Wager Limits

The Jammin’ Jars slot takes place on an 8x8 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.

Jammin' Jars RTP

Jammin’ Jars Theme - Audio and Design Features – head to the dancefloor

Jammin' Jars slot - base game

The design in the Jammin’ Jars slot is bright and bold. With a mirror ball in the backdrop, you’ll first notice the 70s style disco soundtrack playing which is upbeat. The 8x8 grid is set on a dancefloor as you’ll see 6 different fruity symbols.

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. Payouts start at 0.1 times your total stake if you land 5 of the lowest value blueberry. They can reach 100 times your total stake if you manage to find 25 or more of the strawberry in combination.

The most important symbol is the jam jar wild as these benefit from multipliers. When you get a cascading win, the multipliers increase by 1 every time.

You can play Jammin’ Jars on desktop, tablet and mobile devices as it uses HTML5 technology. In fact, Push Gaming has been produced with portrait mode in mind. The 8x8 grid works well on smaller screens.
