Pragmatic Play · 2020
Clusters of five or more matching symbols pay on the 8x8 grid of Gems Bonanza, a high volatility Pragmatic Play slot.
The demo is free, the real game needs an account and players aged 18+.
On the 8x8 grid, a win forms when at least five matching symbols touch horizontally or vertically. The Aztec, gem and treasure theme shapes the look of seven symbols, from the red ruby to the blue gem. After each win, the winning symbols are removed and the grid refills, which the game calls Tumble. One spin can therefore produce several wins in a row.
After a win lands on a marked spot, a random coloured mark can start one of five spin modifiers: Nuclear, Wild Gem, Squares, Colossal Symbol or Lucky Wilds. Collecting 114 winning symbols in a single base spin opens Gold Fever, a five-level Bonus Game. Each level plays all five modifiers once, in a fixed order, while the win multiplier rises from level to level.

Gems Bonanza features
This block settles how the bonus round starts and what each of its levels does.
Gold Fever starts when a base spin collects 114 winning symbols. Each of its five levels plays all five spin modifiers once, in fixed order: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS. Multipliers rise 2x, 4x, 6x, 8x and 10x across levels 1 to 5.
Base game spinsRising multipliers
The base game runs on an 8x8 grid where a win needs at least 5 connected symbols, horizontally or vertically. After each win the tumble feature refills the grid. A random coloured mark can trigger one of five spin modifiers once a win lands on the marked spot.

Gems Bonanza rounds
Many readers worry they will miss a feature, so each stage below names one event.

Five or more matching symbols connected horizontally or vertically form a win on the 8x8 grid. After each win, the Tumble refills the grid, and that refill can start another win.
Cluster Pays and Tumble drive the base game. A win landing on a coloured mark can trigger one of five spin modifiers: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL or LUCKY WILDS.
Gold Fever starts when a single base spin collects 114 winning symbols. Level 1 runs all five modifiers once in fixed order at a 2x multiplier.
Set your spending limit before the first spin. No one can know a session's result in advance.
Gems Bonanza trial
Trying the reels should not mean staking money before knowing how a round runs.
Each spin on the demo reels costs no money and pays nothing. The real game runs the same reels but needs an account and the legal age of 18+.
Play nowOn the reels, Gold Fever starts only after 114 winning symbols land during one base spin, and how often that happens is not known in advance. No one can count the rounds ahead of time, because each spin is random. The result of one session is random, whatever the RTP version running in the game.
Each spin on the reels is settled against one RTP version. That version is named only in the game rules, so the rules are the place to check which one applies to this lobby. Read those rules before the first spin, because the version sets the long-run return.
Wins on the reels grow as Gold Fever moves through its levels, yet the maximum win of Gems Bonanza is a ceiling reached very rarely. Nothing on the reels shows in advance whether a session will approach it, so the ceiling is a limit to keep in mind, not a target.
Know the reels early
After this, you know the bets, volatility and maximum win before you spin.
Symbols on the 8x8 grid of Gems Bonanza connect horizontally or vertically, and five or more of them make a win. Start at the minimum bet of A$0.20 to watch the tumble and the modes before you raise the stake.
The reels of Gems Bonanza pay in bursts, since high volatility means results vary widely from spin to spin. A big win is possible, but no spin promises one, so plan each session before you start.
Wins on the reels of Gems Bonanza grow with the bet, and a round can carry further through the Gold Fever round, where the multiplier rises from 2x to 10x across five levels.
Each spin of Gems Bonanza starts from a stake of A$0.20 at the lowest, and the highest bet allowed reaches A$240. The tables here use A$0.20, A$0.40 and A$0.50 as examples, not as limits, so choose a stake that suits your budget.
