TNT Tumble: Slot Review

TNT Tumble is the latest edition in the Tumble slot series from Relax Gaming. Using a well-known theme, it invites the player into the dark world of mining where cool features and a smart gameplay awaits. But let’s start with the setting first. Imagine a beautiful mountain valley somewhere in the Alpes and a long abandoned mine shaft standing at the foot of a snow-capped peak, glistening with precious gems. Now it’s your job to start drilling those stones and make a fortune, block by block.

TNT Tumble is a slot with cascading reels, meaning stone blocks will tumble down from the 5×7 grid with each spin. What makes the gameplay somewhat unique is the fact that not all the blocks on the grid have gems. The last three rows are made up of solid (darker) stone blocks and at least one pack of dynamite that turns up on a random position. You need to destroy all the blocks in the darker area for the Free Spins feature to be activated.

Ready to play? Hit the coin button to choose your stakes. This game has a stake range from 10 c/p to £/€100 per spin. You’ll find a medium-high RTP of 96.11 %, which isn’t bad at all. Add to this a flexible volatility rate in the bonus game (players can choose between medium, high and very high) and you’re looking at a slot that’s bound to bore down on your adrenalin levels.

The TNT Tumble mine shaft is packed with precious jewels waiting for you to dynamite them out of the mine. There are gold and silver nuggets, sapphires, emeralds and rubies – the latter awarding you 15 times your stake if you land seven of them in a single spin. As with most slots, you need at least 3 matching symbols on a horizontal or vertical line to make a winning combination.

TNT Tumble: Important Slot Features

Helping you hit those big tumbles is the wild drill symbol. When part of a winning combination, the wild drill doesn’t go off the grid, which means you can stack up to 7 of them worth 50 times your stake! These wilds are only removed when they reach the very bottom of the grid. So you can make huge wins just by getting a bunch of wilds drilling holes across the grid. The base game morphs into a high-speed bonus game the moment all 3 bottom rows are blasted away during a single spin. Initially, 6 free spins are triggered and here you’ve got three Free Spin modes to choose from:

Multipliers: Special stone blocks have 1x – 3x multipliers (very high volatility).

Extra Spins: Special stone blocks contain 1, 2, 3, 5 or 10 extra spins (medium-high volatility).

Multipliers & Extra Spins: Special stone blocks contain multipliers or extra spins (high volatility).

Unlike in the base game, blasted stone blocks are not replaced with new ones in the bonus game. Clearing every third row will award you 2 extra free spins. Destroying special stone blocks awards even more free spins and if you hit the multiplier blocks your wins will grow exponentially with every new spin.

Let’s not forget about the dynamite symbol. This one turns up both in the base game and in the bonus round game. When part of a winning combination, it explodes, demolishing all other blocks on that same row.

In TNT Tumble Slot, you can actually buy your way into the bonus game. You’ll find the golden Buy Button in the left bottom corner of the game grid. For a cost of 70 times your stake, you can unlock the bonus game without having to spend another second in the base game.
