Cluster Tumble Slot Demo - Free Play

A Lara Croft-inspired character is your host as you play the Cluster Tumble online slot from Relax Gaming. Aztec, Ancient Egyptian, and Chinese symbols appear in the center of an 8x8 grid and fill more of the game on any sequence of consecutive wins.

Stone blocks reveal special modifiers, such as persisting wilds or transforming symbols, and there’s a free spin bonus feature where multipliers can lead to wins of 20,000x your wager. Cluster Tumble is a high volatility slot, with average returns of 96.4% that you can play on PCs and mobiles. Join the adventure at the best slot sites to unlock the secrets of the Aztecs.

When you load the Cluster Tumble slot machine on a PC, iOS, Android, or Windows site, there’s a brief introduction featuring a newspaper headline about a missing explorer and his wife, who is on a mission to find him. The animated heroine of this adventure stands to the side of the game, while the 8x8 matrix of stone blocks is held in place by highly detailed golden gargoyles. 

It’s a suitably dramatic sight that matches the theme, and an eerie tune plays out as symbols drop into place.

Those symbols come from ancient cultures around the world and include a scarab beetle, an Aztec mask, and a traditional Chinese dragon. Colorful jewels also appear, and it’s your task to claim wins from clusters of 4 or more of the same type of symbol.

The controls are very easy to use, and you just click the pile of coins button to unlock wager options from $0.10 to $50. The arrow within a circle triggers an autoplay feature, and the double arrows activate fastplay mode. Tap the 3 lines on the control panel, and you'll see a list of how much each symbol is worth and how the gameplay and features can land some big wins.

The most valuable dragon head pays 1x the stake for the minimum cluster of 4, and you win 2,000x from clusters of 40 or more.

At the start of a game, only a few symbols appear in the central part of the grid, but if you form a winning cluster, the emblems in the win vanish, along with any adjacent symbols and stone blocks. The second part of the name of this slot comes from the way that symbols above then tumble down to fill the gaps.

If this forms a new cluster, the tumbles continue, and you steadily fill more and more of the 64 positions. Random stone blocks hold special modifiers which become active when they are adjacent to a win.

The ‘W’ wild symbol acts like any other if it can, then improves a cluster, while the lightning bolt turns into a random symbol that pays out in any position, not just when clustered together. A Fire Transform block turns 1 to 2 others into more examples of a single type on the next tumble. A further wild symbol can step in for others and has up to 5 lives, which decrease each time it’s part of a win during a series of cascades.

There are 2 pathways to an exciting free spins bonus feature. You get 5 free spins if you clear the whole grid, or if 3 golden scatter symbols appear at once. If you clear the grid in a free spin, you get 5 further bonus games with a 3x multiplier, and this increases to 6x, 9x, and so on with any further clearances in the round. Any scatter symbols appearing in a free game also add 1 extra spin to your total.

The free spins end automatically if you are fortunate enough to win a total of 20,000x your stake during the round. Play at the maximum wager of $50.00, and you could win $1,000,000 from the Cluster Tumble slot game.

This is a high-volatility game that has a long-term payback percentage of 96.4%.

With a colorful pick of symbols from around the world and an exciting adventure theme, this action-packed game is sure to please. The fast-paced gameplay, with tumbling symbols, extra blocks becoming active, and in-game modifiers, adds drama to any spin. The greatest payouts come during the free games, although you’ll need to clear the grid several times over to build a multiplier big enough for a 20,000x win.
