With a name like “Tutan Kha-boom” you’ll know what to expect from Thunderkick’s latest. Yes, this is indeed a slot that pairs an Egyptian theme with explosions, as winning combinations see the symbols literally blow up. Add explosive wilds and an unusual setup that works from the bottom up and you have the makings of a unique slot. But is this truly the case? Find out in the definitive Tutan Kha-boom review, of course.



The first thing you’ll notice about Tutan Kha-boom is the game grid. After all, this is a slot with 3 reels, each 5 rows tall. It has a total of 99 winning combinations, but these start from the bottom row. Paylines still require at least 3 symbols on adjacent reels, so essentially imagine a typical 5-reel, 3-row slot game that’s been rotated by 90 degrees counter-clockwise for a good idea of how Tutan Kha-boom plays.
Winning combinations in Tutan Kha-boom come with a cascade mechanic, as the symbols making them will inevitably blow up. This leads to new symbols dropping to fill the empty spaces, and if new paylines land through this then the cascade mechanic repeats until there are no more wins in view. Cascades are linked to the game’s multiplier which grows with the spin’s consecutive wins.
Tutan Kha-boom has a fairly low RTP of 94.17% plus high volatility. Wins hit frequently enough during our testing, but these tended to be on the smaller side. Speaking of wins these can reach up to 5,000x the stake. Betting can start from as low as £0.10, and you can adjust the size of your stake after any regular spin by simply clicking the “Bet” button.

Tutan Kha-boom takes place in a cartoon version of an ancient Egyptian tomb that’s all about bold graphic design. While the background is attractive enough, with its shades of purple and orange, it’s the symbols that are the game’s true stars. There are 6 of these mummy heads, and each one blinks with expectation on the reels or, if they land just right, explode in a shower of rags as they set off a cascade.
Since we’ve mentioned the paying symbols, these consist of the high-paying queen and heads in purple, red, green, teal, and blue. The head holding a bomb is the exploding wild. This can substitute for all symbols and will explode when part of a win, destroying all symbols in the same reel and row as it does. The last symbol on the reels is the glowing golden skull, which is the scatter. Land 3 of these for a round of free spins.
These are the values of the paying symbols:
Tutan Kha-boom is a slot that’s particularly well suited for mobiles. It is not only an HTML5 game, making it compatible with anything that can run an internet browser, but has a vertical design that’s ideal for smartphones held in portrait mode. Combined with the bold graphics it makes for a game that’s perfect for the small screen. Of course it still plays well on your tablet, not to mention laptop or desktop PC.



Tutan Kha-boom has a couple of bonus features, a progressive multiplier and a free spins round. Let’s see what they involve.
The cascade mechanic in Tutan Kha-boom is combined with a progressive multiplier. The spin multiplier starts at 1x, but doubles with each consecutive cascade to 2x, 4x, 8x, 16x, and finally 32x. You can see the current size of the multiplier underneath the reels. Once the spin is over the multiplier resets back to 1x.

Landing 3 scatters awards you with a round of 10 free spins. These add a wild collection feature where every 3 wilds collected remove the lowest multiplier and add +1 spin to the total. Collect 15 wilds and you’ll unlock a 64x multiplier. The free spins can be retriggered, as landing 2 scatters awards you with +3 spins and 3 scatters +7 spins.
Note that Tutan Kha-boom has a win cap of 5,000x the stake. If your each this total win during the free spins then the round ends immediately, with the payout awarded and any remaining spins forfeited.

While Tutan Kha-boom brings something of a twist on the typical slot, it’s perhaps limited compared to many other modern video slots. Sure wins start from the bottom and there is a cascade mechanic, but these are hardly revolutionary features by this point. If anything they are marred by a low 94.17% RTP, as well as wins that reach just 5,000x stake. Sure the visuals are cute and explosions thrilling, but it does little else to retain one’s attention.
