Where to Play Jammin' Jars
Jammin' Jars RTP and Wagering
Jammin’ Jars does not have the typical 5x3 video slot layout and instead has eight reels and eight rows. Winning combinations are created by landing clusters of 5 or more matching symbols. Instead of the usual spinning reels, the symbols fall from above and the symbols just need to fall next to each other in clusters in order to trigger a win. The bet level varies from between £0.20 and £100 per spin.
With an RTP of 96.83%, this is slightly above the industry average. However, it is important to highlight that this is a theoretical percentage based on very complex calculations. The Jammin’ Jars maximum win is up to 20,000x your stake. Since the game also has a Cluster Pays mechanic this means that when you trigger a cluster win those symbols will disappear from the grid and more symbols will fall from above meaning that you can trigger consecutive wins in the same spin. Each consecutive win also triggers a multiplier increase of 1x.
Jammin' Jars Symbols and Audio & Video Design
The various fruits on the grid board attract players plus the disco party soundtrack while playing. Players will be entertained by the music of the '70s upon loading the game. The disco ball on the left side of the game window and the spotlights catch the biggest attention. The cool graphics and fruity symbols as well as the smooth animations make it a high-quality game. Once the light is on, one big fruit will come out.
Jammin' Jars come with 6 regular symbols of colourful blueberries, apples, plums, raspberries, oranges, and strawberries. The strawberry is the most rewarding, giving players a one-time take for the cluster of 5. The most important symbol is the wild jam jar. It gives players the chance to grow their multipliers.
You can find the symbols and some of their corresponding payouts below. Since the game has the Cluster Pays mechanic we are highlighting the payout for 5 matching symbols, which is the minimum amount to trigger a win and 25+ which is the highest possible payout:
Blueberry
5 - 0.1x bet / 25+ - 10x bet
Plum
5 - 0.15x bet / 25+ - 25x bet
Apple
5 - 0.15x bet / 25+ - 25x bet
Raspberry
5 - 0.25x bet / 25+ - 37.5x bet
Orange

Jammin' Jars Mobile Features
One important attribute of slot games is their mobile application. On top of that, Jammin' Jars can be played on desktop and tablet devices using HTML5 technology supporting Push Gaming’s software. Moreover, it is compatible with all mobile devices, such as iPhones, Androids, iPads, and other tablets.
Jammin' Jars Bonus Features
There are plenty of benefits players can enjoy on the 4 bonus features. In the Rainbow feature, 1 or more giant fruit symbols can give you a sure win. On the other hand, the Jam Jar Wilds have multipliers that result in an increase on each win. Also, the Free Games feature, players will have the chance to increase with its multipliers on every collapse.
Rainbow feature
Activation of the rainbow feature is through its winless spin. Here, a rainbow drops on the reels creating a massive fruit symbol. The matching symbol becomes a part of the winning cluster.
Jam Jar Multipliers feature
This unique feature replaces all symbols. When a player lands on a wild, it will get either a free spins feature, plus a re-spin, and the wild will move you down in one position. Also, when all the wilds have moved out, it will continue spinning at the bottom of the reels. Furthermore, this feature begins at 1x and every consecutive win will increase by 1 multiplier. In fact, there is no limit on how high the multiplier can reach.
Free Games feature
This will trigger when landing on 3 or more jam jar wilds in the same spin. The free game features allow players to receive 6 free spins which eventually will increase in each collapse. This allows players to get bigger wins as the multiplier increases.

Jammin' Jars Final Thoughts
Overall, Jammin’ Jars by Push Gaming is a unique and exciting slot game that stands out from the typical spinning reels slot machines. With its cluster mechanic and disco party soundtrack, it offers players a fun and engaging experience.

While there is no jackpot, the maximum win of up to 20,000x your stake is impressive. Plus, with its mobile compatibility, players can enjoy Jammin’ Jars on any device.
Taking all of this in consideration I award this slot game an 8.5 out of 10.
