Tutan Kha-boom: Slot Overview
Among Thunderkick’s earlier standout releases was Esqueleto Explosivo—a Pixar-like slot where singing calaveras replaced traditional spinning reels, belting out short tunes and detonating on wins, while a progressive win multiplier ramped up payouts. It later spawned multiple follow-ups, including a Feliz Navidead edition. Now that familiar Thunderkick concept returns in an ancient Egyptian take. Appropriately named Tutan Kha-boom, it revives the chanting, exploding skulls and multiplier-trail mix that’s already proven its appeal.
A major reason Esqueleto Explosivo worked so well was its symbol cast. Each character felt like a tiny personality, adding heaps of charm to the reels. That same spirit carries into Tutan Kha-boom, only now you’re joined mostly by mummies. The skulls still deliver plenty of musical, tongue-in-cheek character, but this time with an ancient Egyptian flavour to their chants. They appear in a bright, cartoon-style tomb across three stacks, making the presentation easy on both the eyes and the ears.

It feels like a standard 5×3 grid has been rotated to form Tutan Kha-boom’s 3×5 play area. Wins land when symbols link from the bottom upward across 99 connecting pay ways. The game runs on a highly volatile math model, and with stakes set between $/€0.10 to $/€100 per spin, the RTP is 94.17%.
There are six paying symbols in Tutan Kha-boom: singing skulls in blue, green, dark green, orange, and people colours, plus a Cleopatra-style character, paying 0.7x to 5x the stake for landing 5 matching symbols.
Tutan Kha-boom: Slot Features

The kha-boom action is powered by exploding avalanches, climbing multipliers, an Exploding Wild, free spins, Bet+ ante bets, and a feature buy.
Exploding Avalanche & Exploding Wild Symbol
Winning symbols detonate and are then replaced by fresh symbols falling in from above, creating another shot at a payout. With every avalanche, the multiplier increases the multiplier up to x32 in the base game or x64 in the bonus round. The multiplier is tracked beneath the reels and resets between rounds. Avalanches keep going until there are no further wins or wilds left. The Exploding Wild acts as a substitute for every symbol except the scatter. When it explodes, it removes all symbols in its row and column except high pay and scatter symbols.
Bonus Game
Landing 3 scatters activates 10 free spins. While the feature is running, 2 scatters award +3 spins, and 3 scatters award +7 spins. Any time 3 wilds appear during the bonus, it removes the lowest multiplier from the trail and awards +1 spin. Reaching 15 collected wilds opens up the x64 multiplier.
Bet+ & Feature Buys
Players can switch on four Bet+ choices: Bonus Boost at 2x, Bonus Boost Plus at 3x, Bonus Boost Ultra at 5x, and Bonus Boost Extreme at 9x. These make each spin 4, 8, 16, and 32 times more likely to trigger a bonus game, respectively. Alternatively, the bonus game can be purchased outright for 80 times the stake.

Tutan Kha-boom: Slot Verdict
Although Tutan Kha-boom isn’t the straightforward reskin that Esqueleto Explosivo Feliz Navidead was, it also doesn’t arrive packed with blazing-new ideas. Instead, Thunderkick leans on a proven setup and dresses it in an ancient Egyptian theme—so nostalgia and comfortable familiarity do more of the heavy lifting than innovation. For Esqueleto Explosivo fans, that recognisable feel is likely a benefit rather than a negative, even if a desire for something more original might still pop up.
That said, a few tweaks stand out—most notably the shifted play area—and it can take a little practice to read wins forming from the bottom row upward rather than left to right. There are also far more ways to win: 99 instead of the original 17. Symbol payouts have been raised as well, which helps explain why the win potential has grown from a modest 700x to a more modern 5,000x the stake. Volatility has also been adjusted from low to high, giving Tutan Kha-boom’s numbers a more up-to-date profile.
Beyond that, Tutan Kha-boom largely sticks to the familiar routine—great for players enjoying the throwback vibe, but potentially less exciting for those hoping for bigger changes. Visually, it’s an attractive slot with plenty of sing-along personality, letting fans revisit the concept through a different cultural theme, though the lower RTP and the absence of a major mechanical step forward may deter others.
