An 8x8 grid holds 64 positions, filled with seven coloured gem symbols and a Wild. Wins come from clusters of at least five matching symbols that connect horizontally or vertically. After each win, the winning symbols disappear and new ones drop in to fill the gaps, a feature called Tumble. A single round can therefore chain several wins. The Aztec, Gems and Treasure theme sets the look of the grid.
Five spin modifiers can appear during base play, including NUCLEAR and LUCKY WILDS. A random coloured mark can trigger one of them after a win lands on that spot. Collecting 114 winning symbols in a base spin starts Gold Fever, a five-level bonus where each level plays all five modifiers once. Its multiplier rises from 2x at level one to 10x at level five.

An 8x8 grid pays when 5 or more connected symbols touch horizontally or vertically. After each win, the tumble feature refills empty spots. A win that lands on a random coloured mark can trigger one of 5 spin modifiers: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL or LUCKY WILDS.

A$0.20 is the lowest bet and A$240 the highest, so you set the stake before the first spin. Each win pays a multiple of the bet you choose.
8x8 is the grid, and a win needs at least 5 connected symbols horizontally or vertically. After each win the tumble refills empty spots, so one spin can chain several wins.
5 spin modifiers can join the base game: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS. Coloured marks can trigger one, if a win lands on the marked spot.
114 winning symbols collected in one base spin start Gold Fever, which has 5 levels. Each level plays all 5 spin modifiers once, and the multiplier rises from 2x to 10x.
A$240 is the highest bet, so set a session limit before the first spin, because no session result can be known in advance. The National Gambling Helpline is on 1800 858 858.

Know what to expect
Read this before you place a first stake, when the bets, volatility and bonus rules still matter.
Bets on Gems Bonanza start at A$0.20 and reach A$240 at the top. The paytable uses A$0.40, and the examples on this page use A$0.40 and A$0.50. Each spin is staked at the bet you choose, so the same symbols pay more at a higher stake.
Gems Bonanza has high volatility, so wins arrive unevenly. A long run of small or empty spins can be followed by a large cluster win or bonus round, and a session can end well below its start. Size your stake to the budget you have set aside.
The lowest stake is A$0.20, so a first round costs little. Use it to watch how the 8x8 grid, the tumble and the Gold Fever levels play out before you raise the stake.
Wins grow through the multiplier levels, which rise from 2x to 10x in Gold Fever. The top result of a single spin depends on chance, so no session can be planned around it.
One RTP version exists, returning 96.55 per cent of the amount staked. That figure is an average over a very long run, so single sessions can land well above or below it. Treat it as a long-run average, not a forecast for one session.
Gold Fever can be bought for 100 times the total bet. At the example top bet of A$0.50, that is A$50. The buy starts the bonus round directly, so you skip the wait to collect 114 winning symbols in base spins.
