TNT Tumble

Our recorded TNT Tumble bonus

We have opened TNT Tumble once on 22 Sep 2026 on stream and logged the result. The best of them paid 44.2× the bet. That is too few open to say anything about how the game behaves — it is a record of what happened on that occasion, nothing more.

Relax Gaming sets TNT Tumble's mining operation in an alpine setting, where a brick-and-iron shaft gives way to a flower-strewn meadow ringed by snow-capped peaks — a warmer backdrop than the underground scenes the Tumble series usually favours. The action plays out on a 5x7 grid where, at the start of each spin, only the top four rows hold active symbols while the bottom three are filled with stone blocks that can be cleared once a win lands beside them.

Matches form from three or more identical symbols connecting horizontally or vertically, and every win destroys the symbols involved along with any stone tiles next to them, letting new pieces tumble in before the process repeats. The pay table climbs through a silver nugget, a gold nugget, and blue, green, orange, and red gems, with the red gem worth 15x the stake for a seven-symbol connection. A drilling wild adds a mechanical twist: rather than clearing when it lands a win, it burrows further down into the stone beneath it, stacking as more drills join in — seven stacked drills are worth 50x the total stake — and it only leaves the grid once it drills all the way to the bottom row.

Clearing every stone block from all three bottom rows in a single spin unlocks the bonus round, which opens with six free spins and a choice of three paths that set both the shape of the round and its volatility: Extra Spins keeps things medium volatility, with special blocks hiding batches of 1, 2, 3, 5, or 10 additional spins; Multipliers & Extra Spins raises volatility to high, mixing multiplier blocks in with the spin blocks; and Multipliers pushes volatility to very high, with blocks worth x1, x2, or x3 added to a running total. Progress on the stone blocks carries between spins rather than resetting, and clearing all three rows again during the bonus adds two more free spins on top. A dynamite block also appears in both the base game and the bonus — when it's cleared, it detonates every other stone block across its row.

A Bonus Buy option skips straight to the feature for 70x the stake. TNT Tumble runs at 96.11% RTP whether or not the bonus is purchased, medium/high volatility, and a maximum win of 12,278x the bet, with stakes from 0.10 to 100 per spin.
