TNT Tumble review

The TNT Tumble slot machine was introduced in 2020 and became the sequel to Relax Gaming’s legendary Temple Tumble Megaways game. In this installment, the developer retained the popular cascading reels mechanic but added unique bonus features. However, the company abandoned the Megaways mechanic, as it was not feasible to implement it in this version.

The TNT Tumble game grid consists of 5 reels, each capable of displaying up to 7 symbols. Initially, only 4 rows of symbols are available; more will open as the game progresses. The maximum win is up to 12,278 times your stake. It’s important to consider the high volatility and the 96.11% RTP when choosing a winning strategy. I’ll tell you more about this game in the review.

Gameplay and symbols

The TNT Tumble game is designed around the theme of gem mining. The game board takes place at a mine entrance, with a stunning wilderness landscape in the background. The game board will thrill you with themed symbols, spectacular explosions, and winning animations. The soundtrack and background sounds create a tense atmosphere and enhance the dynamism of the game.

To win, you need to form a group of 3 to 7 symbols. There are no paylines, but a cluster must consist of at least 3 symbols horizontally or vertically. Wild symbols greatly help in collecting winnings and increase the slot machine’s potential. Before the spin begins, you can choose a bet between $0.10 and $100 per spin.

The symbols are represented as gemstones and ore. Gems bring large wins but rarely form winning combinations, while ore becomes the basis for regular wins and keeps your bankroll at its initial level.

Features and bonuses

What makes the TNT Tumble slot machine unique is its set of interesting bonus features.

Cascade Drums

Winning symbols are removed from the playing field and new ones take their place, allowing you to form more winning combinations in a single spin.

Wild

The wild symbol is represented by a drill. When the wild symbol participates in a win, it moves down one position. This continues as long as you manage to form winning combinations or until the wild symbol reaches the 7th row of symbols. Please note that the wild symbol can appear as a stack, which will significantly increase your winning potential.

Free tours

The free spins round can be activated if all the hidden blocks on the playing field in the base game are destroyed. Before the free spins round begins, you can choose a risk level ranging from medium to very high. Depending on your choice, the playing field will receive certain functions.

The bonus round features more wild symbols, and new pink and blue crystals appear in hidden blocks. Destroying a block with a pink crystal increases the progressive multiplier, while a blue crystal awards additional free spins. It’s quite easy to boost the initial 6 free spins.

TNT blocks

In the hidden cells, you can see dynamite. Destroying this block will trigger an explosion that will destroy the entire row and thus increase the grid of the playing field.

Purchase bonus

By paying 70 times your stake, you will instantly activate the free spins round. Given the great potential of the bonus game, this purchase may be worthwhile.

Conclusion

The TNT Tumble game is appealing thanks to its unique game board expansion mechanics and bonus round crystals. By utilizing the unique features of the wild symbol, you significantly increase your winning potential. It’s this comprehensive set of bonus features that makes the slot machine attractive to both beginners and experienced players.
