You can play with wagers from 0.10 to 100 credits. The volatility is medium to high and the RTP – 96.11%. The max win per spin is 12,278 times your stake per spin.

The slot includes a unique way for triggering free spins and 3 modes of them to pick from. These may include extra free spins, multipliers or both. Each mode has a different level of volatility and boosters. In all three of them, you can add extra free rounds. There is a Buy Free Spins option that lets you purchase the bonus round for 70x stake. The wild symbol is a downward drill that doesn’t get destroyed until it reaches the bottom reel. This lets it increase its size up to 7 rows high.

TNT Tumble Design

The game has gems, gold, solver and precious stones mining theme. The 5×7 grid is unique and includes stone blocks and gems in all kinds of vivid colours. There are also TNT icons, special stone blocks, drill wilds. You can land extra free spins and multipliers.

The images are colourful, bright and authentic. The winning combinations are highlighted in glowing orange light and explosions of stone blocks. The soundtrack is atmospheric and relaxing, mixed with stone crashes, wins and explosions. The base mode is set with an amazing nature landscape. At a distance, you can see fir trees, mountain ranges covered with snow and a meadow.

The grid is positioned on the place of an enormous tree trunk. Its frames are made of a complex stone structure. The free spins take place underground. With each successful removing of rows of the bottom reels, the grid moves one position below. You travel down in the ground and with from each round in free spins. TNT Tumble is innovative and original.

TNT Tumble Gameplay

The game uses the tumbling mechanism. In it, 3 or more matching symbols in a horizontal or vertical position pay you. You will be rewarded for the largest matching combination. There are 35 symbols per spin arranged in 5 reels and 7 rows. Once a spin has started, the bet level is set, locks and cannot be changed.

When you score a win from any symbols without wilds, stone blocks to the left, right, above and below winning symbols crash. They vanish from the grid. The remaining symbols fall down and new ones fill the gaps, which gives you new opportunities to win. This process repeats as long as you score wins. The wild and the other vertically adjacent wilds are destroyed after reaching the bottom row. To be crashed, they also need to take part in one or more paying combinations. Wilds will increase their size in columns on each spin or win.

At the start of a spin sequence, round dark stone blocks and 0 to 3 TNT blocks are positioned on the lowermost 3 rows. When a TNT block gets destroyed, it also destroys the other horizontal stone blocks on the same row. If you crash all dark stone blocks during a spin sequence, you will trigger 6 Free Spins.

There are silver and gold nuggets, 4 kinds of gems, a wild, TNT stone block, 3 types of multipliers and 5 different Extra Spins symbols. The silver nugget has the lowermost value – 3, 4, 5, 6 and 7 adjacent return 0.20, 0.40, 0.70, 2 and 4 times your bet respectively. The gold nugget pays 0.20 to 5 times your bet for 3 to 7
symbols on successive reels horizontally or vertically.

The blue gem pays 0.20 to 6 times your bet, the green triangular gem – 0.20x to 7x stake for 3 to 7 symbols. The yellow-orange gemstone returns 0.40x, 0.80x, 2x, 5x and 10x stake for 3, 4, 5, 6 and 7 symbols in combinations. The most rewarding of the regular symbols is the green gem. Landing 3, 4, 5, 6 and 7 green gemstones give you 0.50, 1, 2.50, 6 and 15 times your bet.

The drilling wild is very likely to be generated in stacked segments per column. Unlike the other symbols, the wild is destroyed only after reaching the bottom row and taking part in a win. It simply moves to the bottom on each cascade. The drilling wild substitutes for the rest of the symbols. You can also score pure wild wins when there are no other adjacent paying symbols vertically or horizontally. These give you 0.50, 1, 2.50, 6 and 50 times your bet for 3, 4, 5, 6 and 7 wilds. This is the highest payout in the game.
