Introduction
Rather than classic reels, this game uses the “Avalanche” feature. Symbols tumble in from above, and any symbols that form winning combinations break apart to make room for more falling blocks. New blocks can form new winning combinations, leading to a streak of wins in a single round.
There are six types of regular symbols in the game. Coloured gemstones represent the higher value symbols, and coloured rocks the lower. Any horizontal or vertical line of 3 or more adjacent same symbols counts as a winning match. A wild drill helps expand the grid by breaking rocks, and it also multiplies winnings.
The expanding reels feature is what really sets this game apart. Players must break apart rocks in the lower part of the screen, leading to free spins and multiplier bonuses. They can do this by forming winning combinations just above the blocks or hitting a TNT symbol.
We always recommend having a try of this Temple Tumble online pokie game in demo mode before you decide to play at an online casino for real money.
Theme, Graphics & Soundtrack
TNT Tumble is a mining themed game. It takes place against a craggy backdrop of snow-capped mountains and rolling hills, with a forest nearby. Flocks of birds occasionally soar across the sky. It’s easily one of the most visually appealing online pokies we’ve played.
The game itself occurs in a rugged mine shaft. Every spin brings a cascade of new rocks and gemstones, which shatter with a satisfying crunch. Ambient sounds of pick-axes, mining trains and the dismal echoes of underground caverns accompany the player throughout. A suspenseful, old West tune really sets the scene.
One small complaint is that the space bar doesn’t trigger a spin by default, which is a common feature on other online pokies. This feature can be enabled in the menu options, however.
RTP & Volatility
The RTP of TNT Tumble is 96.11%, and it’s a high volatility online pokie with a top win capped at 12,278x. You will have to be patient to achieve those big wins though, as is the case with any high volatility slot.

TNT Tumble Bonus Features
TNT Tumble’s bonus features are built around its mining dynamic. There are two main types of bonus up for grabs:
Drill Wilds
Not only do drill wilds pay the highest multiplier, but they don't disappear like other symbols after a win. They are only destroyed when they reach the bottom layer of blocks, and are included in a win.
Free Spins
Triggered by clearing away all the dark blocks in a single round. You will be awarded with 6 free spins and receive a further 2 for every three rows you manage you to clear. Blocks don’t reset in the free spins round, making this task somewhat easier.
When the free spin round begins, you will have a choice between mining for extra free spins (medium volatility), extra multipliers and free spins (high volatility), or just extra multipliers (very high volatility.)
Which of these options you choose depends on your appetite for risk. Choosing the extra multipliers only option promises much higher volatility, but with it the chance of larger wins.
Final Verdict
TNT Tumble is a brilliantly themed online pokie, which manages to stand out in a crowded field due to its mining mechanics. The "Avalanche" feature will remind players of Gonzo’s Quest, but the aesthetic and game mechanics are sufficiently different to make TNT Tumble stand out on its own.
We especially enjoyed trying to break the dark rocks at the bottom of the screen in search of bonuses. This gives a welcome twist to the usual grid-based online pokie, and was entertaining enough to keep us playing. It presents an ongoing challenge and subplot.
Like all high volatility pokies, TNT Tumble can be punishing in the short term, and requires a great deal of patience if you’re waiting for larger wins. That said, the alpine setting and truly immersive sound effects make this game a truly enjoyable place to spend your time.
