Pragmatic Play · 2020
An 8x8 grid, cluster pays and a progressive bonus round define Gems Bonanza, a high volatility video slot by Pragmatic Play.
The demo is free. Real play needs an account and legal age 18+.
An 8x8 grid is the stage for Gems Bonanza, a video slot from Pragmatic Play with Aztec, gem and treasure themes. Wins are formed by clusters rather than paylines: five or more matching symbols connected horizontally or vertically pay. After each win the tumble feature clears the winning symbols and refills the grid, so one spin can produce several wins in a row.
Six features shape the play, and its progressive structure separates it from other Pragmatic Play slots. Random coloured marks can trigger one of five spin modifiers once a win lands on them. Gold Fever starts after 114 winning symbols are collected in a base spin. Each level guarantees every modifier one play, while the multiplier rises from 2x to 10x.

Ready to spin
Tab77 Casino lays out each bet, payout and limit before the first spin.
A$0.20 is the lowest stake and A$240 the highest bet allowed here. The example tables use A$0.40 and A$10, so each figure scales to the bet you pick.
5 or more matching symbols connected horizontally or vertically on the 8x8 grid form a win. After each win, the tumble feature refills the emptied spots and the round goes on.
5 spin modifiers can be triggered by random coloured marks: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL and LUCKY WILDS. A win that lands on a marked spot is the trigger.
114 winning symbols collected in a base spin start Gold Fever, the progressive 5-level bonus round. Each level plays all 5 spin modifiers once, in fixed order.
A$0.40 is the paytable bet. Set a budget in dollars before the first spin and stop once it is spent. The National Gambling Helpline takes calls on 1800 858 858.
The price is a multiple of the bet, so it moves with the stake; the money at the top example bet is in the table.

Spot the features
After this gallery you will have seen the bonus round, the base game and a win.
114 winning symbols in one base spin open Gold Fever, the progressive bonus round, but how often that happens is not known in advance. The result of one session is random, and the RTP of 96.55% describes the long-run return across very many spins, not what any single session will pay. Two players with the same settings can finish with very different balances.
96.55% is the RTP figure listed for Gems Bonanza, but which RTP version Tab77 Casino runs is shown only in the game rules. Check the game rules for the version that applies before you play, and read any RTP figure as belonging to that version only.
A$240 is the highest bet allowed on Gems Bonanza here. The maximum win is a ceiling that is reached very rarely, so treat it as a limit on the game, not as an expected result. A bet at the top of the range does not make that ceiling more likely to be reached.

Gems Bonanza briefly
The bonus purchase, maximum win, bet limits, RTP and volatility, answered from the game's own rules.
The Gold Fever bonus can be bought for 100 times the total bet. At the A$10 example bet, the purchase costs A$1,000. Gold Fever can also be reached in the base game by collecting 114 winning symbols in one spin.
A trial stake of A$0.20 is the lowest bet on Gems Bonanza, so a first session can start there. The modes described on this page show how clusters, tumbles and modifiers work before a larger stake is set.
The biggest single win cannot be known before a spin. It depends on how clusters, tumbles, modifiers and the Gold Fever levels land in each round. No top result can be predicted from one session.
Gems Bonanza accepts stakes from A$0.20 up to A$240 per spin. The examples on this page, A$0.40 and A$10, illustrate the figures and do not set the limits.
There is one RTP version, at 96.55 per cent. The return to player is a long-run average, so a single session can land well above or below it.
Gems Bonanza has high volatility. Wins come with less regularity than in low-volatility slots, and the size of a win can vary widely from one round to the next. How often Gold Fever arrives cannot be known in advance.
Players must be 18+. Help is available from the National Gambling Helpline on 1800 858 858 and through BetStop, the national self-exclusion register.
Decide how much you can lose on Gems Bonanza before the first spin, and keep that amount in a separate budget.
Choose the moment you will stop before each session, and keep that rule after a big win as well as after a loss.
Set a deposit limit and a loss limit in your account before the first session, so each cap applies before any stake is placed.
If Gems Bonanza stops being fun, take a break from the account, or self-exclude through BetStop before the next session.
