Introduction to Tutan Kha-boom
Tutan Kha-boom is a casino slot from Thunderkick, inviting you to a peculiar spot in Ancient Egypt, where vocalising skulls will grace you with a one-of-a-kind musical performance. In the style of the studio's hit release from 2015, Exqueleto Explosivo and its two sequels launched in the following years, the game resounds with quirky chanting of skeletons whenever you hit a winning combination on the grid. This time, however, their rhythm and style change from the energetic mariachi music to slower, more mysterious tones, matching the spirit of old Africa. The game has been designed primarily for the mobile portrait view, shifting the 5x3 grid to a vertical orientation and making paylines run from bottom to top instead of left to right. With an offbeat, polished theme and classic avalanche mechanics empowered by increasing multipliers up to x64, it's shaping up to be a prime slot to play on the go.
Join the chorus of singing skulls and follow the music to win up to 5,000x the bet or explore the features risk-free in the demo mode available at the top of the page.
Theme, Gameplay & Payouts
Tutan Kha-boom is a video slot from Thunderkick with 3 reels, 5 rows, and 99 paylines. The game offers a wide range of bet options, allowing you to choose your stake from as little as a Min.bet of 0.10 up to a Max.bet of 100. Running the game's engine is a default RTP of 94.17%, which is significantly lower than the industry average, so be mindful of potentially lower long-term returns. You'll also experience high volatility, which should make wins less frequent but more valuable on average, while the maximum prize achievable within a single spin is 5,000x the bet. The game has a hit frequency of 30.31%
Follow the energetic Egyptian beat echoing between the walls of an ancient pyramid and reach the chamber supported by four massive columns. This is the place where skulls will perform their concerto, stacking up on top of three mysterious jars, five skeletal heads at a time. There's nowhere else to go, so if you're wondering where you should be looking for the legendary treasures, you must start encouraging the dead to sing by creating winning combinations. If you're ready to start composing the masterpiece symphony, you can do so by launching the game on any modern device, whether you prefer to play on a desktop, a smartphone, or a tablet.
Symbols award payouts when you match at least 3 identical instances on any of the active paylines. Qualifying sequences must begin from the bottommost line and continue upward across adjacent rows. There's no clear division into low and high-paying symbols, as all of them are represented by colourful skulls, but one stands out from the line-up with its characteristic golden crown. It's the most valuable symbol that pays 5x the bet for a complete payline. The rest are blue, green, yellow, red, and purple skulls wrapped in bandages, awarding between 0.7x and 2.5x the bet for a 5-of-a-kind hit. Additionally, there are Exploding Wilds in the form of a gold skull with a bomb in its mouth and Scatters represented by a gold skull emanating blue energy.
Special Features & Slot Mechanics

You can win up to 5,000x the bet.
What features are available in the slot Tutan Kha-boom?
The features are Exploding Avalanche, Exploding Wild, Bonus Game, and Feature Buy & Ante Bet.
Exploding Avalanche
Every winning combination bursts into dust, creating vacant areas to which the remaining symbols drop. Next, new symbols fall in from above to complete the view and potentially award more hits. This system allows for creating multiple wins within the same game round, and the sequence will continue as long as new combinations are being created. Additionally, each avalanche increases the progressive win multiplier that starts from x1 and doubles in value with every hit, up to a maximum of x32 in the base game and x64 in the bonus round. The multiplier resets to x1 at the beginning of every new spin.
Exploding Wild
Exploding Wild substitutes for all regular paying icons when paylines are evaluated. Upon landing, and once all wins from the initial drop have been awarded, it explodes, destroying all symbols (except the top-paying ones and Scatters) on its row and column, thus triggering another avalanche.
Bonus Game
Accumulating 3 Scatters anywhere on the grid during a single base game round awards 10 Free Spins. Throughout the bonus game, scoring 2 or 3 Scatters simultaneously awards 3 or 7 extra spins, respectively. Every 3 Exploding Wilds scored removes the lowest multiplier value from the trail, meaning that the meter will reset to the lowest active value at the beginning of the next Free Spin. Collecting 15 Wilds during one bonus playthrough leaves only the highest x64 multiplier active.
Feature Buy & Ante Bet

2x = Bonus Boost, with a 4-times higher chance to trigger the bonus game.

9x = Bonus Boost, with a 32-times higher chance to trigger the bonus game.
80x = instantly trigger the bonus game.
Final Thoughts on Tutan Kha-boom
The original Esqueleto Explosivo was a significant release for Thunderkick, capitalising on new at the time cascading mechanics with multipliers, ushered by the legendary Gonzo's Quest by NetEnt. The singing Mexican skulls element was fresh, entertaining, and gave the game a unique identity, which carried on for years in sequels like Esqueleto Explosivo 2, Esqueleto Explosivo 3, and most recently, in the 2025 release, Esqueleto Explosivo Feliz Navidead. The series consistently remained in the cheerful mariachi atmosphere for over a decade, which makes seeing the same concept reused in an Ancient Egyptian setting quite surprising. And while the African culture may not exhibit the same musical enthusiasm as Mexicans, the creators ensured that the irresistible charm of chanting skulls is no less amusing in Tutan Kha-boom. Visuals have been perfectly adjusted to match the new setting with classic Egyptian imagery, plus everything shines with high design quality and refined finish. On top of all these changes, Thunderkick made a bold move to swap the grid's orientation to vertical, making the game ideal for mobile portrait view, which is not a common practice, but may ultimately boost the reception on portable devices.
Unfortunately, big changes in the theme are not followed by the mechanics. Tutan Kha-boom is a bit of a comfortable reboot in that matter, reusing the setup we've seen a good while ago in the second instalment of Esqueleto Explosivo. The multiplier increase during avalanches is still the core element of the gameplay, and the only new-ish addition is the Exploding Wild that clears symbols from its row and column. In the bonus game, removing the lowest active multiplier through collecting said Exploding Wilds is exactly what we've dealt with before. It's a shame that the studio didn't feel adventurous enough to supplement the new audiovisual setup with some engaging new features.
Tutan Kha-Boom feels a bit like an Esqueleto Explosivo reskin rather than a refreshing remake, reusing mostly the same technical bits in a new Ancient Egyptian theme.
