Game Setup & Symbols
Cluster Tumble game uses a reel set with a grid layout of 8 reels and 8 rows. However, a huge portion of the screen is occupied by blocker tiles at the start of a spin, allowing players to unlock additional positions on the screen with each winning cascade.
When it comes to pay ways, Cluster Tumble uses a Cluster Pays engine instead of regular paylines. The standard symbols in the game are a dragon, scarab beetle, mask, and three gems of different colours. The pink dragon is the highest paying of these icons.
Wild & Scatter Symbols
- Wild: The Wild symbol in the game is represented by the icon marked W. The symbol appears on block tiles and only becomes active when a winning combination forms adjacent to it. Wild icons can substitute for any of the regular pay table symbols on the reels.
- Scatter: The Free Spins feature is activated when you land three scatters on the reels.
How to Play Cluster Tumble Slot Online
Cluster Tumble is an easy game to play, and you don’t need to have any experience to try it out. Besides, you can opt to play the free or demo version of the game first to learn the gameplay before playing with real money.
To get started, you need to first place a bet by clicking on the icon with coins. The slot offers a variety of bet sizes, and you can choose any coin value between R1 and R125. After placing your bet, you can start the game by clicking on the spin icon.
Payouts are awarded when you land clusters of four or more matching symbols on adjacent reels. The highest standard payout is 2000x the bet, and it is awarded by a cluster of 40 or more pink dragon icons.
Cascading Wins: When you land a win, the symbols forming the winning cluster and those on adjacent reels are destroyed and removed from the screen, paving the way for new ones to take up their position on the reels. The feature continues until there are no new winning clusters.
The Free Spins Bonus is activated when you land three scatters in any arrangement. It can also be triggered by unlocking all blocker tiles on a spin. The round kicks off with 5 free spins, but you can win more by removing all blocker tiles from the grid or by landing scatters during the feature. Clearing the block tiles will give you +3 free spins and a x3 win multiplier, while each scatter will get you one extra free game.
This is a special modifier activated when a winning cluster forms adjacent to a tile with a lightning symbol. When activated, the tile with the lightning symbol will transform into a random regular symbol, prompting other matching icons to create a win regardless of their position on the reels.
Blocker tiles with the fire symbols are activated when a win forms on adjacent reels. The stone block morphs into a regular icon when the modifier is activated, and 1-2 random symbols are also selected to transform into the same symbol during the next cascade.
Bonus Buy Options
You can trigger the Free Spins round with the click of a button at any point in the game, thanks to the Buy Bonus feature. The cost of purchasing standard free spins is 100x the bet, while Volatile Free Spins cost 200x the stake.
The difference between the two free spins modes is that the multiplier in the Volatile feature grows by x6 instead of x3 when you clear all blocker tiles from the screen.
