TNT Tumble Slot: How to Play, Features, RTP & Free Spins

Introduction

TNT Tumble is a mining-themed slot from Relax Gaming and part of its Tumble series, alongside titles such as Temple Tumble. The setting starts as a peaceful meadow, but valuable crystals are buried underneath, and the only way to reach them is to blast through layers of dark stone.

The game combines four main features:

  • Tumbling wins: winning symbols clear so new ones can drop in.

  • TNT: explosives that destroy layers of dark stone.

  • Drill Wilds: wilds that bore down the reels and add to wins.

  • Free spins with a choice: you pick one of three bonus modes.

This guide explains how to play TNT Tumble, how each feature works, and what the RTP and max win figures mean.

What Is TNT Tumble?

TNT Tumble is an in-house Relax Gaming title and one of the studio's Tumble series of grid slots. It shares ideas with Temple Tumble, especially the stone blocks and the choice of free spins modes, but it plays on a different grid with its own mining features. Relax's other in-house games include Bill & Coin 2, which you can play at SpinSaga.

The grid is 5 reels wide and 7 rows deep. At the start, only the top four rows are open, filled with coloured crystals. Below them sit three rows of dark stone, with bundles of TNT hidden inside. Break through all of the dark stone and you drop down into the free spins.

If you're new to how grids, tumbles, and bonus triggers fit together, our guide to how social casino game mechanics work covers the basics.

How to Play TNT Tumble

  1. Open the game in demo mode or at a casino that offers it.

  2. Set your bet. Relax Gaming's official range is $0.10 to $100 per spin, though casinos may set different limits.

  3. Spin. Symbols and stone blocks tumble into the 5×7 grid.

  4. Look for line wins of 3 or more matching symbols in a horizontal or vertical line.

  5. Watch the tumbles. Winning symbols disappear and new ones drop in.

  6. Break the dark stone. Wins next to stone blocks and TNT explosions clear them away.

  7. Clear all the dark stone to trigger free spins and choose your mode.

  8. Check the info screen for symbol values, mode rules, and your casino's RTP version.

Our guide to reading a game's info screen before your first spin explains what to look for.

TNT Tumble Features Explained

Line Wins on a Grid

TNT Tumble has no traditional paylines. Instead, you win by lining up 3 or more matching symbols in a straight horizontal or vertical line anywhere on the grid.

That makes it different from cluster pay slots, where matching symbols can form any connected shape. Here, the matches have to be in a straight line.

Tumbling Wins

After each win, the winning symbols are removed and new ones fall into place. If the new symbols form another win, the sequence continues. Our guide to cascading reels vs traditional slots explains how this compares with standard spins.

Dark Stone and TNT

The bottom three rows of the grid are blocked by dark stone. Winning combinations next to the stone help break it, and TNT blasts through a whole layer of dark stone at once. Each layer you clear opens more of the grid to play on.

Opening up the grid as you win is also part of Leprechaun Heist, where the grid can expand beyond its starting 5×5 size.

Drill Wilds

Drill Wilds bore their way down the reels before adding to the win. Reviews say they can land in stacks that reach all the way to the bottom row, helping to form wins in several places at once.

Free Spins: Choose Your Mode

Clear every block of dark stone and you free-fall into the free spins, starting with 6 free spins. Relax Gaming says you can choose between three volatility options, which reviews describe like this:

Mode

What the Special Stones Hold

Volatility

Extra Spins

1, 2, 3, 5, or 10 extra free spins

Medium

Extra Spins + Multipliers

A mix of extra spins and multipliers

Higher

Multipliers

x1, x2, or x3 added to a progressive multiplier

Highest


According to Relax Gaming, two more rules apply during free spins:

  • Extra spins: clearing every third row of dark rubble awards 2 additional free spins.

  • TNT carries over: TNTs are kept for each spin. Reviews add that cleared stones don't reset between spins.

A choice of free spins modes also features in Torii Tumble, and Bill & Coin offers three bonus rounds to pick from, as covered in our Bill & Coin vs 4TP Pigs N' Pots comparison. Choosing a mode changes how the round plays, not the game's long-term RTP. For a general primer, see how free spins work.

Bonus Buy

Where local rules allow it, you can buy your way straight into the free spins. One review puts the cost at around 70x the bet. Unlike Royal Potato, where the bonus buy raises the RTP, reviews say TNT Tumble's RTP stays the same when you buy.

Buying a bonus doesn't guarantee a return, and chasing bonus buys is one of the common mistakes new players should avoid.

TNT Tumble RTP, Volatility and Max Win

RTP: 96.11%. Review sites list 96.11%, and Relax Gaming's page notes a separate 90% version for Germany. RTP is a theoretical long-term average and doesn't predict any session. Because casinos can run different versions, check the info screen before you play.

Volatility: 4 out of 5. Most reviews describe it as medium-high, and your choice of free spins mode shifts how volatile the bonus plays. See what slot volatility means and our guide to volatility vs RTP.

Max win: 12,278x your stake. Reviewers say the bonus round, especially the multiplier mode, is where the biggest wins are most likely. Wins near the cap are extremely rare. Our guide to understanding social casino game odds explains why.

Is There a TNT Tumble Demo?

Yes. Relax Gaming's official page has a Try Game demo, available after you confirm you're 18 or over. It's a good way to see how the TNT, Drill Wilds, and three bonus modes work before you play for real.

If you want to try a tumble-series slot at SpinSaga, Temple Tumble is available to play with free Gold Coins.
