TNT Tumble is a video slot from Relax Gaming and the second instalment in the “Tumble” series, following the highly enjoyable Temple Tumble Megaways.

As with the first part of the series, the aim is to clear away rock blocks, collecting various boosters like extra multipliers and additional free spins along the way. The game features a Buy a Bonus option, which is a good thing, as the free spins bonus is where this slot truly comes alive.

You can win big on TNT Tumble: the maximum win is no less than 12,278 times the total stake. The game takes place in a mine shaft, where you can dig to your heart’s content, aiming to go as deep as possible. Occasionally, you’ll encounter dynamite sticks, but in this game, they’re a positive feature, helping you shatter the rock blocks.

How does the TNT Tumble slot work

TNT Tumble is a cluster pays slot, where winning combinations are formed by 3 or more identical symbols on a horizontal or vertical line. The playing field is rectangular: 5 symbols wide and 7 rows high.

Bets start from $0.10 per spin and can go up to $100 per spin. The theoretical return to player (RTP) is 96.11%.

Winning combinations disappear, making room for new ones. All rock blocks adjacent to a winning combination are crushed. This is a slot where the values of the symbols are secondary to the game. The wilds are the most important feature: they drill their way down and remain sticky until they reach the bottom row.

Multiple wilds can lead to impressive results, especially when a good extra multiplier is active.

Free Spins Bonus

There are two ways to trigger the bonus game:

  1. By removing all rock blocks from the field
  2. By purchasing the bonus for 70x the total stake

You always start with 6 free spins, but before playing, you need to choose the risk profile you want to use:

The additional free spins can consist of 1, 2, 3, 5, or 10 free spins. The extra multipliers can be +1, +2, or +3.

You begin the free spins bonus at level 1, and if you remove enough stones, you move up a level. While this may sound more interesting than it is, it does grant you +2 free spins each time.


TNT Tumble is a delightful video slot that does things differently, which is why it has been so successful. The free spins bonus rounds, in particular, are so enjoyable that you need to be careful not to spend the entire evening buying bonus features.

Slototimes’ Verdict: TNT Tumble is a highly entertaining slot with unique gameplay elements and a captivating free spins bonus round. It’s certainly worth a spin for UK players seeking something fresh and engaging.
