Free slot: TNT Tumble

How TNT Tumble works

TNT Tumble is a slot machine present in online casinos. It has been published since April 2020 by the provider Relax Gaming. Go to the heart of the valley in search of the precious stones for this new opus in the provider's Tumble series.

The machine comes in a 5 by 7 format, with 5 columns of 7 rows, the last 3 being covered with black stone blocks in the basic set. It features a classic grid operation where different symbols cascade down. The objective is to make adjacent connections to destroy the black stone blocks and thus widen the possible places on the grid. TNT Tumble's payout rate to players exceeds 96% and it can be described as a medium to high volatility machine with a payout of up to 12,278 times its original bet.

The different symbols of TNT Tumble

8 different symbols can appear on the grid:

• TNT sticks: they are present randomly on the black stone blocks. The destruction of a square with this symbol triggers the destruction of the other blocks in the same row.

• a drill as a WILD: the most remunerative symbol (pays x50 for 7 identical symbols), it appears anywhere on the grid and replaces any symbol. WILD symbols can be stacked on top of each other. Unlike other symbols, they do not fade when they are part of a winning combination but move down one position and only fade when they reach the last row of the grid and are included in a winning combination.

• gemstone symbols (pay x4 to x15 for 7 identical symbols).

The different connections in TNT Tumble

TNT Tumble does not work with traditional paylines but with a mechanism of horizontal and vertical lines where a minimum of 3 identical symbols must be connected to pocket a win. The lines can be created anywhere on the grid, as long as the symbols are adjacent to each other. Once the winning line is formed, it will fade away, leaving room for new symbols to form a new line of identical symbols.

How the TNT Tumble bonus works

When all black stone blocks are destroyed, the free spins bonus function is triggered. 6 free spins are awarded. The player must then choose between three additional features with different volatility:

• the multiplier represented by purple crystals: of very high volatility, this feature offers special symbols containing x1, x2 or x3 multipliers.

• additional spins represented by turquoise stones: of medium volatility, this feature offers special symbols containing 1, 2, 3, 5 or 10 additional free spins.

• the multiplier and additional turns: of high volatility, this feature mixes the two previous ones.

A new interface is then revealed in the bottom of a mine with a basic grid similar to that of the base game, with the last 3 rows of the grid covered with blocks of black stones and inlaid with TNT sticks but also with special symbols depending on the choice of features. Multipliers and additional free spins add up to the end of the bonus. When all black stone blocks are destroyed and the grid is fully revealed, 2 additional free spins are awarded. Bonus buy-in is possible on TNT Tumble for 70 times the amount of your bet.

Our opinion about TNT Tumble

Thanks to its original mechanism, the quality of its animations and its bonus function with various possibilities, TNT Tumble offers a pleasant gaming experience for slot machine lovers. After Temple Tumble and Tower Tumble, the provider Relax Gaming is expanding its range of Tumble machines with TNT Tumble. While the possibilities in the base game remain limited, once the bonus interface is unveiled, multipliers and extra spins will offer great opportunities to hit the jackpot on this medium to highly volatile machine.
