Breaking news: A famous explorer disappears in the Himalayan wilderness, and his adventure-loving wife goes on a solo rescue mission to find her missing husband. In just a few short sentences, Relax Gaming sets the scene instantly for a fresh-new adventure-themed video slot, inviting you to join this risky escapade.

Set in Nepal and playable on a huge 8×8 grid with Cluster Pays mechanics, you’ll be exploring sacred temples in an attempt to clear special stone blocks from the reels. The more you can clear during free spins, the bigger the multiplier you’ll receive, with the game culminating in possible wins of up to 20,000x your stake!

Cluster Tumble Bonus Features

With 4 bonus features, including cascading reels, there’s more to Cluster Tumble than it first appears. Wilds have up to 5 lives, persisting multipliers increase by 3x and the special stone block symbols reveal hidden slot features in both the base game and the
bonus round.

The Buy Bonus option here allows non-UK players to pay their way into the free spins round as an additional bonus feature. At 100x your stake, you can activate the regular free spins round and at a whopping 200x your bet, you’ll trigger the volatile version.


If they can, wilds will always substitute for all other symbols to complete a winning combination. Some will even have 1-5 lives, which is a fantastic feature. If a wild has more than 1 life, it will decrease each time the symbol is used in a winning combination, meaning the wilds will stay sticky and do their job until they lose all their lives or fall off the face of the grid.


Scatters in Cluster Tumble unlock free spins, but you’ll need to land at least 3 of these gold-plated symbols all at the same time to activate the bonus round.

Special Stone Blocks

Look closely at the wall of grey stone blocks. While most of them are empty, some may contain greyed-out symbols with special features. You’ll see them activate whenever a win occurs directly adjacent to these symbols:

  • Wilds – substitute for all symbols.
  • Lightning Win – turns into a normal paying symbol and triggers wins with such symbols regardless of their position on the reels.
  • Fire Transform – turns into a normal paying symbol and encourages other 1-2 symbols to transform into the same paying symbol on the next tumble.

Free Spins

You need to either land 3 scatters or clear all stone blocks from the grid in the base game to trigger the free spins round with 5 free spins. Clear the blocks during free spins, and you’ll receive an extra batch of 3 free spins plus a persisting multiplier. Starting at 3x, the multiplier increases by 3x each time you clear the grid. So, the next time the clearing happens, you’ll receive a multiplier of 6x, then 9x, 12x, 15x and so on.

For each scatter landed, you’ll receive an extra free spin, plus all the special stone blocks stay active, creating quite the buzz during free spins.

Cluster Tumble Jackpot

There are no jackpots appearing inside the ancient temples, but there’s an excellent top reward set for freeing the explorer. Find him, and you’ll be awarded a max win of 20,000x your stake.

RTP and Volatility

Cluster Tumble is a high volatility type of slot, which feels fast-paced in general, but not when it comes to big wins – they’ll take their time to manifest. Nevertheless, they’ll be rewarding. Equally rewarding is the game’s non-variable RTP rate of 96.40%.

Where to Play Cluster Tumble
