Before the tumble, after the tumble
Useful the moment you sit down and need to know what happens between two spins.
-
1
Where do you set the stake?
Set your stake through the bet control, anywhere from A$0.20 to A$240 per spin. The amount applies to the cluster pays and to the tumble that follows, so fix it before you start rather than adjusting mid-round.
-
2
Count five connected gems
Connected gems pay as a cluster when five or more touch horizontally or vertically, with no payline drawn anywhere. Every winning cluster clears, columns collapse and new symbols drop in, so a single press can produce a chain of paid results.
-
3
Which modifier fires, and when?
Coloured marks can appear randomly on the grid, and a winning symbol landing on a mark fires one of five modifiers: Nuclear, Wild Gem, Squares, Colossal Symbol or Lucky Wilds. Multipliers climb as the chain of tumbles continues within the spin.

Gold Fever without collecting
Collect 114 winning symbols across a base spin and Gold Fever opens, guaranteeing all five modifiers in a set sequence at 2x, 4x, 6x, 8x and 10x. Alternatively the round can be bought outright at 100 times your bet, or A$100 on a A$1 stake.

5
A ceiling set before, not after
Decide on a ceiling for the session before the first spin, because each tumble invites another press and the round never announces its ending. Deposit limits, loss limits and session reminders sit in the account settings and apply without waiting.

Removes the doubt about what the modifiers and the tumble actually look like in play.

Gems Bonanza: Gold Fever and the tumbling base round
Five modifiers, one pass each?
Five levels play in a fixed order, each guaranteeing one spin modifier once: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL, LUCKY WILDS. Collect 114 winning symbols in a base spin to start it; the multiplier climbs 2x, 4x, 6x, 8x, 10x.
Before a mark fires, after it settles
Clusters need 5 connected symbols horizontally or vertically, and every win tumbles: symbols clear and the grid refills. Coloured marks can appear at random and fire one of the five spin modifiers after a win lands on the marked spot.
Skipping the collection for a set price
Practice first, then decide on A$0.20
Practice run without stakes
An 8x8 grid refills after every cluster, and the demo runs the same mathematics without a stake. Nothing you collect there can be withdrawn.

Play for moneyHow Gems Bonanza runs for Australian players
Your top end of the slider — A$240 →
Bets open at A$0.20 and stop at A$240, the highest stake allowed here. A maximum win figure for this slot is not stated on any screen in the game, so none is quoted.
Leave the spins running
Autoplay is available to players in this market, so the grid can keep resolving without a tap between rounds. Every spin still costs the same stake whether you press or the game repeats it.
Gems Bonanza lets you pay in
Bonus buying is allowed in this market, which means the paid Gold Fever entry sits open at 100x the bet. The price is fixed, and the round that follows is never guaranteed to return more.
What no one can tell you in advance
Don't plan around the target
Collecting 114 winning symbols in a single base spin opens the Gold Fever round, and how many spins that takes varies from session to session without warning.
Long-run figure, short-run noise
A 96.55% return is calculated across a vast number of rounds, so any single session can close far above or far below that line.
Rules screen versus assumption
Pragmatic Play builds more than one return version of this slot, and only the rules screen inside the game states which one is running here.
Can you reach the ceiling?
The top prize exists as a ceiling in the game design, and reaching it depends on multiplier levels lining up rather than on anything a player controls.
Long-run average before a single spin
Return to player is a long-run average over millions of spins, and operators may run the 96.55% version listed. The exact version on your game appears in the rules screen.
