Choose Gems Bonanza if you want a cluster pays slot with Aztec, gem and treasure themes. It runs on an 8x8 grid, and a win forms when at least five matching symbols connect horizontally or vertically. After each win, the tumble feature removes the winning symbols and refills the grid, so new wins can form within the same spin. Random coloured marks can also trigger a spin modifier when a win lands on them.
Pick this slot when a bonus round that climbs in stages matters most to you. Gold Fever starts when a base spin collects 114 winning symbols. It has five levels, and each level plays all five spin modifiers once, in a fixed order: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS. The win multiplier rises from 2x at level one to 10x at level five.

Useful when you want to see the board and the bonus stage before choosing a bet.
Two play styles
Knowing what starts each round removes the guesswork before a bonus lands.
Reach 114 winning symbols in a base spin to start Gold Fever. 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 rises from 2x at level 1 to 10x at level 5.
Base game spinsUp to 10x
Choose a bet and aim for five or more connected symbols, horizontally or vertically, on the 8x8 grid. The tumble feature refills the grid after each win. Random coloured marks can trigger one of five spin modifiers once a win lands on the marked spot.
Placing a betWins and modifiers
Clear path to wins
This block settles how one round runs, from the bet you pick to the feature that pays.
Pick a bet between A$0.20 and A$240 before the first spin. The stake sets what each spin costs, so check the total bet on screen before you press spin.
A win forms when five or more matching symbols touch horizontally or vertically on the 8x8 grid. Winning symbols clear, new ones tumble down, and each new cluster that lands pays again.
Coloured marks can trigger one of five spin modifiers once a win lands on them. The modifiers are NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS.
Collecting 114 winning symbols in one base spin opens Gold Fever. Its five levels each play all five modifiers once, in fixed order, and the multiplier rises from 2x to 10x.
Set your spending limit before the first spin and keep each bet inside it. A higher bet, from A$0.20 up to A$240, uses the same budget faster.
Choose your bet size knowing that nobody can predict when the Gold Fever bonus round will arrive. The base game is random on every spin, so how often a session reaches the bonus cannot be known before you play. The RTP is an average over a very large number of rounds. It does not forecast your session, which can end well above or below the amount staked.
Open the game rules before you stake, because only the rules show which RTP version this casino runs. Compare the figure in the rules with the one shown on this page before you deposit. The rules are the only place where this casino states its version, so use them as the reference for every session.
Read the maximum win as a ceiling that very few rounds reach, not as a sum to expect. Gems Bonanza can pay up to its maximum only in rare sequences that no player can plan for. Set your budget around what you can afford to lose, since the ceiling says nothing about how a session ends.
Two modes to compare
The first worry is whether trying Gems Bonanza will cost real money.
Choose the demo to learn the rules, because it needs no money and pays nothing. The real game needs a Miamiclub Casino account and the legal age of 18+.
Start playingGems Bonanza essentials
Before a spin, many players want to know what the bets, RTP and bonus cost are.
Choose your bet before you judge the top prize, because the money paid scales with the stake. The Gold Fever multiplier climbs from 2x at level 1 to 10x at level 5, and bets run from A$0.20 to A$240.
Decide on the buy only after you check the total bet. Buy Gold Fever costs 100 times the total bet, which is A$200 at the example top bet of A$2. The buy starts the bonus round without collecting 114 winning symbols in a base spin.
Read the paytable before any real stake, since it shows what each symbol pays at A$0.50. Check the bet range of A$0.20 to A$240 in the game before you pick a stake.
Check the RTP before you stake, because it sets the long-run return of the game. Gems Bonanza has one RTP version, 96.55 percent, and that return is shown per A$100 staked. A single session can land well above or below it.
Expect long runs without a win, because Gems Bonanza has high volatility. No one can tell in advance when a win or the Gold Fever bonus will come.
Pick a stake from A$0.20 up to A$240 per spin, as the game allows. The A$0.50 and A$2 bets on this page are examples only, not the limits of the game.
Beyond Gems Bonanza

Take a break as soon as the game stops being fun, and self-exclude through BetStop if you want to stop for longer.
