Gems Bonanza Slot Review

Gems Bonanza Slot Overview

The legend of El Dorado sent explorers into the jungle after a city of gold that nobody ever found. Pragmatic Play hands you the map instead: in Gems Bonanza, coloured marks behind the gems trace a path across an Aztec temple, and a win on top of one sets off a spin feature. If there is treasure at the end, it is capped at 10,000x stake.

The game came out in October 2020 on an 8x8 grid. Five or more matching gems pay when they touch side by side or one above the other.

There are no free spins. Gold Fever starts once one spin sequence clears 114 winning symbols, and its multiplier climbs from 2x to 10x over five levels. Pragmatic Play lists the RTP at 96.51%, and the rules rate it medium volatility. We also review Pragmatic Play's Star Bounty, Ultra Hold & Spin, Chilli Heat and Mustang Gold.

We like how much a single base game spin can hold: tumbles, up to five spin features, then more tumbles, paid as one total at the end. There may be no free spins, but Gold Fever replays every feature with a multiplier on top, which gives the bonus more shape than a plain count of spins. If we had one gripe, it is the 114-symbol trigger. It suits players who like a busy grid and prefer medium volatility to high.

How To Play Gems Bonanza Slot

Pragmatic Play sets stakes at £0.20 to £100 a spin; UK rules cap each spin at £5, or £2 if you are 18 to 24. Pick your total bet and spin. Clusters of five or more matching gems pay. A cluster of 25 or more pays between 50x and 1,000x your stake, depending on which of the seven gems it is.

The game holds your winnings until the spin is over, then pays every tumble and spin feature in one total. Each cluster pays only its highest win. Separate clusters on one screen add together, and a single Wild can complete several clusters of different gems at once.

Gems Bonanza Slot Paytable & Symbols

Seven gems pay, listed from the top gem to the lowest in the order of Pragmatic Play's game rules. Each value is a multiple of your total bet. The rules group bigger clusters into bands, so the 9 Symbols column covers clusters of 9 to 11, the 12 column 12 to 14, the 15 column 15 to 19, the 20 column 20 to 24 and the 25 column any cluster of 25 or more. The Wild has no pay of its own and only reaches the grid through the Wild Gem and Lucky Wilds features.

Gems Bonanza Slot Features

Tumbles keep one spin alive

Winning clusters disappear and new gems fall into the gaps. The chain stops when a tumble brings no new win and no spin feature.

Five coloured marks, five spin features

Coloured marks can appear behind the gems on any base game spin. Win on top of one and its feature plays after the last tumble.

Blue gives Nuclear: the grid clears and refills with new gems.
Pink gives Wild Gem: every copy of one random gem on screen turns Wild.
Brown gives Squares, random 2x2 blocks of one gem.
Red gives Colossal Symbol, one 3x3, 4x4 or 5x5 block of a single gem.
Green gives Lucky Wilds, 5 to 15 Wilds in random spots.

Win on several marks at once and the features play in a fixed order, Nuclear first and Lucky Wilds last. Pink and green are the two we rate highest, because nothing else puts a Wild on the grid.

Gems Bonanza Slot Bonus Features

Gold Fever, five levels deep

A meter counts every winning symbol that explodes during a spin's tumbles and resets when they stop, so all 114 points must come from one sequence. Hit 114 and Gold Fever starts at level 1 once the spin ends.

Each level plays all five spin features in order, with a multiplier on every win. Clear the next target and you move up.

Level 1 starts from the 114-point trigger and plays at 2x.
Level 2 needs 116 winning symbols and plays at 4x.
Level 3 needs 120 and plays at 6x.
Level 4 needs 125 and plays at 8x.
Level 5 needs 132 and plays at 10x.

Miss a target and the round ends. It also ends once level 5 has played its features, and only then does the game pay the whole Gold Fever win.

Gems Bonanza Gold Fever starting at level 1 with all wins multiplied by 2 — Gold Fever level 1 at 2x

Gems Bonanza Gold Fever at level 2, all wins multiplied by 4 as the Wild Gem feature fires — Level 2 at 4x

Our Verdict While the multiplier ladder is easy to read, it is steep. Reaching 10x means clearing four targets in a row after a 114-symbol trigger, so we treat level 5 as a long shot. With no free spins anywhere, this ladder is the whole bonus.

The demo runs the full game with play money. Watch the coloured marks behind the gems: a win on a pink or green one is the only way a Wild reaches the grid. Keep an eye on the Gold Fever meter too, which empties after every spin sequence that falls short of 114 winning symbols, before any real money goes down.

Gems Bonanza Slot RTP & Volatility

Pragmatic Play's game page lists an RTP of 96.51%. Review sites list three settings, 96.55%, 95.54% and 94.53%, the first matching the rules file we read. They also put the max win at 10,000x stake, a figure the studio's page leaves out. Casinos pick the setting, so open the in-game rules and check before you play.

Our Verdict Although 96.51% is the headline figure, the lowest setting sits almost two points below it, and the casino lobby will not tell you which version you have. The in-game rules will. The setting can change from one casino to the next.

Gems Bonanza Slot Graphics & Audio

Graphics

Pragmatic Play's page sells the game as a treasure hunt, with the coloured markings forming a path across the 8x8 grid. The grid sits inside an Aztec temple, where a carved stone face drips molten gold and a tall statue keeps watch on the right. We like the stone face more than the gems.

Audio

The music is drums and flutes, played to build tension. The game rules give you separate switches for the ambient music and the sound effects, so you can keep one and mute the other.

Our Verdict We like that the map is more than decoration. The path of coloured marks Pragmatic Play describes is the same set of marks that fires the spin features, so the artwork shows you where to look. If the drums and flutes wear thin, you can mute the music and keep the effects.

Gems Bonanza Slot on Mobile

Unlike most lost temples, this one can be reached from the sofa, and nobody has to hack through the jungle with a machete first. Pragmatic Play's Gems Bonanza runs on Android and iOS, on phones as well as tablets, and you can also play it on a desktop computer.
