Learn how Jammin' Jars plays before spinning
An 8x8 board of fruit symbols opens each round of Jammin' Jars. A win needs five or more matching symbols touching horizontally or vertically, anywhere on the grid, because the game has no paylines or ways. Winning symbols are removed, the rest collapse downward, and new symbols cascade in to refill the board, so one spin can chain several wins. Fruits, Neon and Party are the themes behind this same mechanic.
Three or more Jam Jar symbols landing anywhere on the board start the Free Games Feature, which awards 6 fixed free spins. Those spins use the same cluster and cascade rules. In the base game, the Rainbow Feature can strike after a non-winning collapse. Giant Fruit Symbols then convert every position they cover to one fruit type. It never runs during the free spins.

Three Modes, One Board
Jammin' Jars free games and rainbow feature
After this section you will know how each mode starts and what it gives you.
Jammin' Jars Rainbow Feature
A random feature that can follow any non-winning collapse or cascade in the base game. It adds one or more Giant Fruit Symbols of a single fruit type, and each board position they cover turns into that fruit type. It does not run during the Free Games Feature.
Non-winning cascadeGiant Fruit Symbols
Jammin' Jars base game
Each spin is played on an 8x8 grid with cluster pays. A win is 5 or more matching symbols touching horizontally and/or vertically anywhere on the board; winning symbols are removed, remaining symbols collapse downward, and new symbols cascade in to refill.

Five things to know
Jammin' Jars from bet to final reel
Rich Casino explains each round in plain steps, so you know the rules before the first spin.
A$0.20 floor, A$100 ceiling
A$0.20 is the lowest bet, A$100 the highest. Every win and free spin is paid as a multiple of the bet, so A$1 pays five times what A$0.20 pays.
Wins with no paylines to track
Five or more matching symbols touching horizontally or vertically form a win. Winning symbols vanish, the rest drop down, and new symbols fall in.
Jammin' Jars Giant Fruit Symbols
One or more Giant Fruit Symbols of one fruit type convert every board position they cover. The random Rainbow Feature fires after a non-winning collapse and never during free spins.
Jammin' Jars free spins trigger
Three or more Jam Jar symbols anywhere on the board start the Free Games Feature, with 6 fixed free spins under the base game's cluster rules.
Keep your budget in hand
A$100 is the highest bet, so set your limit before the first spin. Results of a session cannot be known in advance, and a round can end without a win.

Past spins tell nothing about the next bonus
Three or more Jam Jar symbols anywhere on the 8x8 board start the Free Games Feature, but no one can say when they will land. How often the feature comes is not known in advance. One session is random, whatever RTP applies, so a long dry run does not mean a hit is due, and a quick hit does not mean the next one follows.
96.49 and 96.83 are the two RTP versions of this slot. Which version runs on this site is shown only in the game rules. RTP is a long-run average across many spins, so it says nothing about what one session will return to you.
x19,998 of the stake is the maximum win of Jammin' Jars, a ceiling that a session reaches very rarely. Read it as the top of the paytable, not as an expected result. At the A$1 top bet, that ceiling equals A$19,998, and at the A$100 max bet it equals A$1,999,800.
Know what you risk
Quiet base game, loud bonus
What this slot is, how it pays and what it costs to play, in short answers.
How is Jammin' Jars different from Jammin' Jars 2?
19,998 times the bet is the top prize here, while Jammin' Jars 2 in the same series lists 50,000 times. Its RTP is 96.40, below the 96.49 and 96.83 versions of this slot, so the two games do not pay alike.
How high is the volatility of Jammin' Jars?
5 or more matching symbols touching each other form a win, and volatility is high, so payouts can swing widely. A session can end well above or well below where it started, and no one can say in advance which.
What is the maximum win on Jammin' Jars?
19,998x the bet is the top win: A$19,998 at A$1, or A$1,999,800 at the highest bet of A$100. The multiple is fixed, so the cash amount grows with each bet you place.
Can I buy the bonus in Jammin' Jars and what does it cost?
84 times the base bet is the price of the Free Games Feature bought through Bonus Buy. At A$1 that comes to A$84. Buying skips waiting for three Jam Jar symbols to land.
How do I get free spins on Jammin' Jars?
3 or more Jam Jar symbols landing anywhere on the board trigger the Free Games Feature. It awards 6 fixed free spins, played under the same cluster and cascade rules as the base game.
What is the RTP of Jammin' Jars and its versions?
96.49 and 96.83 are the two RTP versions, meaning the share of stakes returned over a very long run. A single session can land far from that figure, in either direction. The table on this page gives the return per A$100 staked for each version.
When is it time to stop playing?
Players must be 18+. For help in Australia, call the National Gambling Helpline on 1800 858 858, or register with BetStop, the national self-exclusion register.
Stop when budget runs out
Set a budget before you spin and treat it as the most you can lose. When it runs out, stop, even if a bonus looks close.
Stake more after a win?
Choose your stopping point before the first spin and keep it after a win too. A big win can tempt you to raise the stake.
Jammin' Jars caps come first
Set deposit and loss limits in your account before you play, so the cap is already in place when a session runs long.
Walk away from chasing losses
If the game stops being fun, take a break or self-exclude through BetStop rather than chasing a loss.
Before the next spin
Lobby browsing once the session ends
Useful once you want a different slot and need to compare how each one pays out.
