Five figures
Star Casino lists each figure with its meaning, so you know the game before the first spin.

An 8x8 grid of gems forms the playing field, framed by Aztec, Gems and Treasure themes. Wins do not come from lines. A cluster needs at least 5 matching symbols that connect horizontally or vertically. After each win the tumble feature refills the grid, so one spin can pay several times. The seven symbol types run from the red ruby to the blue gem.
114 winning symbols collected in one base spin start Gold Fever, the progressive bonus round. Its five levels each play all five spin modifiers once, in a fixed order: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS. The win multiplier climbs from 2x at level one to 10x at level five. Random coloured marks in the base game can also trigger a modifier.

Five levels, five modifiers
We show each rule in order, so you know what to expect before the bonus starts.
Gold Fever starts after 114 winning symbols are collected in a base spin. Its five levels each play all five spin modifiers once, in fixed order: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS. The win multiplier runs 2x, 4x, 6x, 8x and 10x, one step per level.
Base game winsRising multipliers
Base play uses an 8x8 grid where five or more connected symbols, linked horizontally or vertically, form a win. After each win, the Tumble feature refills the grid. Random coloured marks can trigger one of five spin modifiers when a win lands on a marked spot.

Play guide
Read this before your first spin, when you want to know what each spin does on screen.
A$0.20 is the lowest bet. The examples on this page use A$0.20, A$0.40 and A$0.50, while the highest bet allowed is A$240.
5 connected symbols form a win on the 8x8 grid, horizontally or vertically. After each win, the Tumble feature refills the empty spots with new symbols.
5 spin modifiers sit behind random coloured marks. A win on a marked spot can trigger one of them, while Wild symbols and Cluster Pays shape the base game.
114 winning symbols collected in one base spin start Gold Fever, a progressive bonus round with 5 levels. Each level plays all 5 spin modifiers once, in a fixed order.
A$0.20 per spin is the smallest stake, so the session total depends on the bet and the number of spins. Set that total before the first spin.
Visual tour
After these four screens, you will have seen a win, Gold Fever and the base grid.
The 8x8 grid of Gems Bonanza is no guide to when the Gold Fever bonus round arrives, and how often it comes is not known in advance. The result of one session is random, whatever the RTP of the version in play. High volatility means long stretches without a big return can happen, and no table on this page changes that.
From A$0.20 a spin, the RTP of Gems Bonanza depends on the version Star Casino runs. Only the game rules name that version, so read those rules before judging the return figure in the table above. The table gives the money return per A$100 staked, and the rules tell you which version that return belongs to.
A$240 is the highest bet allowed here. The maximum win of Gems Bonanza is a ceiling reached very rarely, not a result to plan around. Reaching it depends on chance, like any other win on the reels.
Players must be 18+. Help is available from the National Gambling Helpline on 1800 858 858, and BetStop is the national self-exclusion register.
Decide how much you can afford to lose on Gems Bonanza before the first spin, and keep that amount separate from money you need for bills.
Pick the moment you will stop before you spin, and stick to it after a win as well as after a loss on Gems Bonanza.
Use the deposit and loss limits in your account settings so that a long session on Gems Bonanza cannot take more than you planned.
If Gems Bonanza stops feeling like entertainment, step away for a while, and if the urge to keep going grows, talk to someone you trust.

Gems Bonanza answers
After this, you will know the bets, the volatility, the bonus cost and the RTP before you spin.
A$0.20 is the lowest bet on Gems Bonanza, and A$240 is the highest allowed here. The A$0.20, A$0.40 and A$0.50 bets on this page are examples only, not the limits of the game.
An 8x8 grid carries high volatility in Gems Bonanza, so sessions can be uneven. Quiet stretches may be followed by sharp swings in your balance, up or down.
100x the total bet is the price of the Gold Fever buy, which comes to A$50 at A$0.50. The buy starts Gold Fever directly, without collecting 114 winning symbols in a base spin first.
96.55 percent is the only RTP version of Gems Bonanza, shown per A$100 staked in the table on this page. RTP is a long-run average across many rounds, so it says nothing about a single session.
