How to play Jammin' Jars (members only)
Wins pay for groups of matching symbols that touch horizontally or vertically. Larger clusters pay more, and winning clusters usually disappear to make room for new symbols.
Jammin' Jars is played on a 8×8 grid with cluster pays.
- Set your stake. Choose your total bet per spin. Wins are paid as multiples of this stake.
- Check the paytable. Open the game's info screen to see what each symbol pays and the exact rules for this version.
- Spin. Each spin's result is decided by a certified random number generator, independent of previous spins.
- Trigger the bonus. Land the required scatter symbols to start the free spins feature.
- Optional bonus buy. Where permitted, pay a fixed price to start the bonus directly.

How winnings work (members only)
What 96.83% RTP costs per $100 wagered, the 20,000x max win at a $1 stake
The top prize is capped at 20,000x your stake. On a $1 spin that is $20,000; on $0.20 it is $4,000. When the cap is reached the round usually ends immediately.
Because wins don't depend on lines, every symbol in view can count towards a pay. The paytable lists how many matching symbols each tier needs.
Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.
Because winning symbols tumble away and are replaced, one paid spin can produce a chain of wins. All of them count towards that spin's total.
What 96.83% RTP means
Expected return = stake × 96.83%
Over $100 of total bets, the long-run average loss is $3.17
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a high volatility game.
Features explained (members only)
6 features explained: free spins, multipliers, wild symbols, tumbling reels and more
Free spins
A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.
Multipliers
Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
Tumbling reels
After a win, the winning symbols are removed and new ones fall into their place. This can create several consecutive wins from a single paid spin. Also called cascades or avalanches.
Bonus buy
Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).
Cluster pays
Wins are formed by groups of matching symbols touching horizontally or vertically, rather than along lines.
Strategy tips (members only)
- Size your stake to the volatility. High volatility concentrates the return in rare, large wins. Long losing runs are normal. Keep stakes small (around 1% of your session budget or less) so you can ride out the swings. A simple rule: bring at least 300 spins' worth of budget, so a $50 budget suggests a stake of about $0.17.
4 more tips and a session planner
- Check which RTP version you're playing. Push Gaming offers this game at 96.83%, 94.25%. Open the game rules at your casino and prefer sites running the 96.83% version.
- Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
- Bonus wagering: at 96.83% RTP, clearing $1,000 of wagering costs about $31.70 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
- Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
