The Relax Gaming video slot Cluster Tumble has 8 rows and reels. Landing four or more of the same symbol kinds in a cluster results in a winning cluster. You have the option of placing a minimum wager of 0.10 or a maximum wager of 50. The game's RTP is 96.40% in normal mode, but it can be raised to 96.57% by using the Bonus Purchase option. High volatility can be seen in Cluster Tumble, where a lucky player may win up to 20000X their original wager.
Blue, green, and red gems are the lower paying symbols. 50X the stake is paid when 40 or more of the same symbol type are landed. A mountain lion, a scarab, and a mask are the symbols that pay out more. The payout for landing 40 or more of a single symbol type ranges from 100X to 2000X the stake. The red W that serves as the game's wild emblem can appear anywhere and grant players up to five additional lives. The game's scatter symbol is a golden icon with a skull on top. You may also be able to land special stone blocks during the spins that display a W, a lightning bolt, or a flame.
The Free Spins feature begins when you clear all of the stone blocks from the reels or hit three scatter symbols. Five free spins will be awarded to you as a welcome bonus, and you can earn additional free spins by spinning all the reels. Following that, you'll get 3 further rounds of free spins along with a 3X win multiplier. The win multiplier will then steadily increase by 3X each time the reels are cleared, and it will continue to apply to any wins made and held during the bonus game. One additional spin is awarded for each time a scatter symbol lands on the reels.
