Jammin’ Jars Slot Review by Push Gaming

Jammin’ Jars is a fruity cluster slot from Push Gaming. The London studio announced it on 18 September 2018. The theme is a disco full of dancing fruit.

The game uses an 8×8 grid with cascading wins. Jam Jars act as wilds and scatters, and each one carries a multiplier. A Rainbow Feature adds random surprises.

This review uses Push Gaming’s own game page for the main facts. We also mark which details come from our earlier review and could not be verified.

Jammin’ Jars at a Glance

Developer Push Gaming
Announced 18 September 2018 (Push Gaming)
Grid 8×8 cascading clusters (confirmed by Push Gaming)
Win rule Clusters of 5 or more symbols (confirmed by Push Gaming)
RTP 96.83% or 94.25%, depending on the casino (confirmed by Push Gaming)
Volatility High (confirmed by Push Gaming)
Highest observed win 19,998.5x (confirmed by Push Gaming)
Bonus buy Available (confirmed by Push Gaming)
Bet range $0.20 to $100, according to our earlier review
Please note: Push Gaming says RTPs may vary per casino. It lists 96.83% and 94.25%. Always check the version at your casino. The bet range, the free spin count and the sticky wild details come from our earlier review. Our earlier text also gave a max win of $2,000,000 and 20,000x. We use the developer’s highest observed win instead.

Theme, Graphics and Sound

The reels are full of berries, plums and other fruit. They dance across a disco floor. The look is bright, juicy and fun.

Each win makes the winning symbols collapse. New fruit then cascades in from above. As a result, the screen is always in motion.

A cheerful theme with a high volatility engine is an unusual mix. Our guide to popular slot themes online shows other creative styles.

Betting Range

Our earlier review listed bets from $0.20 to $100 per spin. Push Gaming does not state a range on its game page. Check the bet selector at your casino.

Because the volatility is high, a modest stake keeps your session going. Pick a bet that gives you plenty of spins.

RTP and Volatility

Push Gaming lists two RTP values: 96.83% and 94.25%. Operators choose which version to offer. Our guide to RTP and online slots explains why this matters.

Push Gaming rates the game as high volatility. Expect long quiet spells, and then sudden big moments when the jars line up.

How Cluster Wins Work

You win by landing clusters of matching symbols. Push Gaming says you need five or more. The symbols must touch each other on the 8×8 grid.

After a win, the winning symbols vanish. New ones drop in to fill the gaps. This can create a chain of wins on one spin.

Term Meaning
Cluster A group of 5 or more touching symbols
Cascade Winning symbols vanish and new ones drop in
Grid 8 reels by 8 rows

Jam Jars: Wild and Scatter

The Jam Jars are both wild and scatter symbols. Each jar carries a multiplier that starts at 1x. The multiplier applies to every win the jar contributes to.

According to our earlier review, a wild jar moves down one position after each use. It keeps going until it leaves the grid. We could not verify that detail.

Rainbow Feature

The Rainbow Feature triggers at random. Push Gaming says it brings massive fruits onto the dance floor. These can burst into wins.

Our earlier review said it comes after a non-winning spin. A rainbow drops, and a large fruit symbol forms. Matching fruit next to it joins the cluster.

Free Games

Three or more Jam Jar scatters start the free games. Multipliers join the action during this feature. Push Gaming does not state the number of spins on its page.

Our earlier review said you get 6 free spins. It also said the starting jars stay sticky, and new wilds stick too. In addition, the multiplier does not reset after a losing spin. We could not verify these details.

Tip: The free games are the main route to a big win. Plan your bankroll so you can play long enough to reach them.

Bonus Buy

Push Gaming lists a bonus buy option for the game. It lets you pay to enter the free games straight away. This option is not available everywhere, so check the rules where you live.

Buying a bonus costs a lot at once. Use it only if the cost fits your budget.

Strategy and Bankroll Tips

  • Choose a stake that gives you at least 200 spins.
  • Check which RTP version your casino uses.
  • Avoid bonus buy unless it fits your budget.
  • Set a loss limit before you start.
  • Take regular breaks.

No tip changes the odds. Every spin is random, and earlier results never affect the next one.

Mobile and Demo Play

Push Gaming calls the game mobile-first in its launch announcement. It plays well on phones and tablets. Check your casino’s game list to confirm.

A demo is a safe way to learn the features. Our guide to free online slots explains how to practise.

How a Typical Session Plays

The base game is cheerful and fast. Clusters form, vanish and refill. Many wins are small.

The tension grows when jars appear. Each jar adds a multiplier, and two or three can build a big win.

Free games then bring the biggest swings. A strong round can change your balance quickly.

Jammin’ Jars Compared with Other Cluster Slots

Area Jammin’ Jars Many cluster slots
Grid 8×8 Often 6×6 or 7×7
Wild Jam Jars with multipliers Often none
Volatility High Varies
Bonus buy Yes Often

The multiplier jars and the large grid set this slot apart.

Why the Multiplier Jars Matter

Most cluster slots add a single multiplier to the whole round. Jammin’ Jars gives each jar its own multiplier. A win only benefits from the jars that help form it.

This creates a nice balance. A jar in the middle of a big cluster is far more valuable than a jar on its own. As a result, you always watch where the jars land.

The jars also work as wilds. They can complete clusters that would otherwise miss. In addition, they can start the free games.

However, high volatility means big jar wins are rare. Enjoy the spins, and treat a large result as a bonus.

Getting Started with Jammin’ Jars

Start with the demo if your casino offers one. Spin for a few minutes and watch how the main features work. This costs nothing and shows you the pace of the game.

Next, open the paytable. It shows the symbol values and the rules at your stake. As a result, every spin makes more sense.

Then move to real money at a small bet. A modest stake gives the bonus round time to appear. Finally, decide your limit before the first spin and keep to it.

Playing Responsibly

High volatility games can empty a balance quickly. Set a budget before you play and keep to it. Use deposit limits and reality checks if your casino offers them.

Players must also be of legal gambling age in their country. Never chase losses. Stop if gambling stops being fun.

Who Will Enjoy Jammin’ Jars?

Player type Good fit?
Fruit and disco fans Yes. The theme is cheerful.
Fans of cluster slots Yes. The 8×8 grid is large.
Players who like multipliers Yes. Each jar has its own.
Players who want low volatility No. Push Gaming rates it high.
