Gems Bonanza symbolWhen European colonists first set foot on the Americas, they found a continent rich with minerals. The civilisations that ruled over what we know today as central and southern America were wealthy in gold. Wealth was abundant in the lands of the Aztecs, the Maya, and other ancient nations that once ruled those lands. Perhaps not as abundant as Gems Bonanza makes it seem, but enough to warrant continental expeditions by European monarchies. You can also get a slice of that wealth using the tumble bonus, spin special features and the Gold Fever!

Visually, we would not classify this slot as the most detailed we have seen. However, Pragmatic Play have created some striking graphics for this title! The one that immediately caught our eye was the stone head, where melted gold is constantly pouring down. To the left side of the reels, we also see a bridge lit by candles that leads to… something. There are not enough details to tell exactly what is there, but it looks cool either way. Now let’s delve deeper into this new Labslots review.

How it Works

You play this online slot on an eight-reel board that uses cluster pays instead of a traditional paylines setup. In theory, this makes landing a winning combination much easier. In order to win, you only need five matching symbols in adjacent positions. They can be connected horizontally or vertically, but not diagonally. You do not have to worry about starting with the leftmost reel, or strictly following a payline to claim a cash prize. The user interface will be immediately familiar to any fan of Pragmatic Play. Through it, we can spin the reels, set up Auto Play, change our total bet and open the paytable. Additionally, we can turn sound on or off and open the settings menu. You can change your bet using the plus and minus keys. Players can wager between £0.20 and £100.00 on each spin.

Icon designs look good, but are not very exciting. We have a variety of gems that come in different shapes and colours. It makes them visually distinct, but they all kind of blend together after a while. This is an unfortunate reality with most cluster-pay titles like Gems Bonanza. The symbols would be rather interchangeable if it were not for the fact they have vastly different payouts. A green gem on a golden background is the Wild. There are no other special icons on the playing field.

Gems Bonanza Bonus Rounds

After every spin, existing winning combinations will blow up and disappear from the reels. However, the gap they leave behind is not there for long! Already present symbols will fall down, filling in any empty positions. Meanwhile, brand new icons appear at the top of the reel, ensuring there is always a full board of symbols. If another winning combination occurs, the same process repeats itself. Tumbling continues until no more wins occur.

Every standard spin will occasionally see coloured marking appear beneath certain icons. Whenever a win happens on top of that marked position, it activates a special feature. You can activate five in total! All five are played after all tumbles for the current spin are completed.

  • Blue marks award the Nuclear bonus. Existing symbols are removed from the playing field and are replaced with brand new ones.
  • Pink marks grant Wild Gem. One icon is chosen randomly from the playing field and is turned into a Wild.
  • Brown marks award Squares. 2×2 blocks of randomly selected symbols are placed on the board.
  • Red marks grant Colossal Icon. A random block of 3×3, 4×4 or 5×5 symbols are added to the playing field.
  • Green marks award Lucky Wilds. Between five to fifteen Wilds are added in random positions to the board.

Each Tumble win slowly fills the meter. When a certain number of icons is reached, the Gold Fever special feature activates. The bonus starts at level one. You are guaranteed to play each one of the spin modifiers once during each level. As you advance through the levels, the number of winning symbols and the win multiplier increase.

We love cluster pay slots, so Pragmatic Play’s latest title was right up our alley. The special features they added give this game many opportunities to win big. Spin modifiers combined with Gold Fever are super lucrative, and incredibly rare. You should take the high volatility tag for this release seriously. It is possible to win a huge 10,000x jackpot. However, you should prepare for a long grind before you are able to score that prize. Check out our list of slot sites to see where you can try it out!
