Bonus Features in TNT Tumble

You’d hope that a slot with TNT in its name would offer plenty of potentially explosive gameplay. Thankfully, TNT Tumble doesn’t disappoint on that score. There’s plenty going on here including free spins, extra spins, multipliers and drilling wilds. Central to the action is the tumbling reels game mechanic which we’ll look at first.

Tumbling Reels feature

When you get a winning combination, winning symbols  are removed and new ones replace them. The tumbles continue if a new winning combination is created.This feature can be found in many slots like Gonzo’s Quest (by NetEnt).

You’ll see another 3 rows below the main set that are locked. The blocked stones directly left, right, above or below winning symbols are unlocked. The tumbles continue into these positions. After a tumble where no new winner is formed, the reels revert to their original 5 reel, 4 row set up.

TNT blocks feature

TNT stone blocks appear in the locked positions at the bottom of the reels. When a TNT block is unlocked, it explodes and opens up all of the symbol positions on that row.

Free Spins feature

If you manage to get on a roll with the cascades and open up the whole 5 reel, 7 row grid you’ll trigger the Free Spins feature. Your reward here is 6 free spins. You can vary the volatility here too thanks to 3 different bonus extras. In all cases, the cascading reels are active:

  • Extra Spins: choose this round and extra spin symbols are added. These can add 1, 2, 3, 5 or 10 extra free spins to your total when opened. This is a medium variance pick.
  • Extra Spins and Multipliers: in this round, a combination of extra spin and multiplier symbols are added. This is a high variance choice.
  • Multipliers Only – This super volatile choice adds 1, 2 and 3x multiplier stones into play. You will only play 6 free spins here.

TNT Tumble Slot RTP, Details and Wager Limits

The action in the TNT Tumble slot starts on a 5 reel, 4 row grid. Winning combinations are formed by landing 3 or more matching symbols, vertically or horizontally. You can play TNT Tumble from between 10p and £100 per spin.

You can spin using the space bar if you wish. Alternatively, you can set 5, 10, 15, 20 or 100 autoplay spins as well as win and loss limits. There’s also a turbo mode option.

The RTP is 96.11% which is about average. We found the variance to be in the medium to high range overall. You can of course make your own pick when you trigger the Free Spins feature. The maximum win overall is 12,278 x stake. On each spin though, you could win 2,088 x your total stake.

TNT Tumble Theme – Audio and Design Features – crisp display that’s easy on the eye

TNT Tumble slot - base game

The design in the TNT Tumble slot is nicely done. Set against a backdrop of green fields and snow-capped mountains, the reel grid is set within a mine shaft.

The reels are made up of just 6 standard symbols. There are 2 lower value nuggets as well as 4 more brightly coloured crystal symbols which are potentially more rewarding. The best of the quartet is the red crystal which pays 15 x your stake if you land 7 in combination. Better still is the drill wild. Land 7 of these for an award of 50 x your total stake.

There’s also a wild which replaces all the standard symbols. They don’t disappear if they form part of a winning combination. Instead, they act like a drill and drop down towards the bottom of the grid. Only when they reach the bottom do they disappear.

The cascading reels means that there’s plenty of moving parts in play here. Relax Gaming has done a good job with the design though. The limited number of symbols mean that everything is clear and easy to follow. The animations are nice and smooth too.

There’s a reassuring thud as each cascade takes place. That’s complemented by a slightly futuristic-sounding backing track. It’s as slightly unusual fit for the theme but does the job. There are plenty of options to set things up how you like. As well as autoplay and spin speed, you can also vary the sound effects and backing track to your liking.

The paytable is very straightforward too. Relax Gaming has done a solid job here. Relax Gaming has created a TNT Tumble mobile slot. The design works well enough, despite all the moving pieces. It’s a game best enjoyed on a bigger screen but playable enough on tablet or mobile.

TNT Tumble Review Summary – tumbling reels deliver some dynamite action

We’ve seen plenty of slots with similar gameplay to TNT Tumble. The tumbling reels deliver plenty of action though, in both the base game and thee free spins round. The ability to play the free spins at different levels of volatility is plus too.

The design is simple enough but the clean visuals are very easy on the eye. Put that combination of slick design and explosive gameplay and in TNT Tumble you have a potentially dynamite slot. If you want dynamite though, nothing will beat the Bonanza Megaways slot by Big Time Gaming which is arguably the most popular online slot around.

? What is the TNT Tumble free spins round?

The Free Spins feature is triggered by opening up every position on the 5×7 reel grid. You’ll then receive 6 free spins with multiplier symbols added, a combination of extra spin and multiplier symbols or just extra spin symbols. The variance changes with each.

Yes, you can play a version of TNT tumble that is fully optimised for play on a mobile phone or tablet device. The slick design works well on the smaller screen and the potentially explosive gameplay is the same regardless of what device you’re playing on.
