Load the Gems Bonanza slots game onto a PC, iOS, Android, or Windows at one of the best mobile casinos and you are transported to an Aztec setting, where molten gold pours from a stone carving, and a circular structure stands to the side of the grid. Markers on this object light up as any of the 5 in-game modifiers activate.
The symbols consist of 7 colourful gems, plus a gold and emerald wild that can act as any other if it helps to create a win, or can increase the size of a cluster. Graphics are excellent here, with lots of colour and detail, and there’s a dramatic soundtrack that matches the eerie atmosphere.
The tumbling reels mechanism can lead to several wins in a row and trigger a Gold Fever progressive round. The in-game features are guaranteed during the Gold Fever games, and you can collect multipliers of up to 10x.
You can play for between 0.20 and 100.00 per spin at the casino slots online, making the Gems Bonanza slots game suitable for everyone from casual players to high rollers. You simply click plus and minus tabs either side of the spin button to select a bet level. Other control buttons activate Autoplay spins, and the ‘I’ takes you through to the paytable.
Here, you’ll see how much you win when matching gems cluster together in groups or lines of 5 or more. Blue diamonds pay the least and max out at 50x your stake for clusters of 25 or more. Red gems are the most valuable, worth 1000x when at least 25 group together.
Winning gems vanish and new ones drop from above to fill the empty spaces. With luck, this tumbling reels system leads to further wins and more tumbles. Random positions on the 8x8 grid will light up with coloured markers in each spin. If a win happens on top of a marker, you benefit from a modifier, and its possible to trigger several at once.
The blue Nuclear modifier removes all symbols to leave space for a replacement set. The pink Wild Gem transforms all examples of a random symbol into extra wilds. The brown Squares feature sees a random symbol appear in 2x2 size. The red Colossal Symbol modifier adds 3x3, 4x4, or 5x5 blocks of a random symbol to the grid, and between 5 and 15 random wilds appear in the green Lucky Wilds feature.
If you collect multiple bonus features at once, they play out one after the other in the order listed above. When the tumbling reels mechanism removes 114 symbols in a sequence, you enter the Gold Fever round. Wins from the next spin and any subsequent tumbles get doubled and all 5 in-game modifiers play out in each spin.
Further levels unlock if you remove enough symbols, with higher multipliers applied at each step. If you remove 132 symbols, it triggers the highest level, where a 10x multiplier applies to any further wins. The Gold Fever round ends on a losing spin or at the end of a series of tumbles.
At the maximum multiplier, you can win a vast 10,000x your stake from this high volatility game. That’s a cool 1,000,000.00 if you play with 100.00 per spin. The Gems Bonanza slot machine pays back at a higher than average rate of 96.51%.
Gems Bonanza follows the hugely popular Aztec theme and comes packed with bonus features. You won’t trigger an in-game feature on every spin, and a win isn’t guaranteed from any of them, but we found that once active, more often than not you will win a prize.
