Symbols and Payouts

Each spin stars with the layout of 5 reels and 4 rows. Additional rows are covered with stone blocks, which can be removed by forming winning combinations next to the blocks. 

Winning combinations form with three matching symbols in a cluster. After the win is counted, the symbols disappear and new ones fall into place. This avalanche-like feature continues until there are no more winning combinations. Furthermore, if a TNT Stone block gets destroyed, it also destroys any other dark stone block on that row.

TNT Tumble symbols include rocks and crystals – three most valuable symbols are colorful crystals, which payout from 7x to 15x times the bet for 7 matching symbols. 

Drill Wilds

Bonus Wild symbol pays out impressive – 50x times the bet for 7 matching symbols. It will substitute for any other standard symbol in the game.  

Wilds can create stacked segments on each column. Unlike the other symbols wild symbols are not destroyed by a win, instead, they are destroyed when they fall down to the bottom row and are included in a win.

Drill Wilds

TNT Tumble Free Spins

If all dark stone blocks in the main game are destroyed, the Free Spins feature is awarded. Players can choose between three different Free Spin modes.

TNT Tumble Free Spins

Multiplier (medium volatility)
– special stone blocks contain 1x, 2x or 3x added Multipliers


Multipliers & Extra Spins (high volatility) – special stone blocks contain added Multipliers or extra spins

Extra Spins (very high volatility) – special stone blocks contain 1, 2, 3, 5 or 10 Extra spins. In all different modes, clearing every third full row of dark stone blocks, regular and special, awards +2 free spins.

Furthermore, in Free Spins, some dark stone blocks are special and contain extra spins or added multipliers.

TNT Tumble: Verdict

TNT Tumble is a fun grid slot with a fantastic bonus game with different options and diverse volatility levels. Furthermore, Drilling Wild feature is the game saver in both base game and bonus features. This simple but well-considered game is one of the best from recent Relax Gaming slots. Ee also liked Mega Masks slot, you can definitely see the similarities between these two games.
