Tutan Kha-boom

Tutan Kha-boom: Slot Overview

Tutan Kha-boom is a high-volatility slot from Thunderkick that reworks the studio's beloved singing-and-exploding-symbol formula into an ancient Egyptian setting. It follows the same DNA as an earlier hit from the studio built around musical, characterful symbols, this time recast with a cast of chanting mummies instead of the original cast.

Theme and Gameplay Feel

The reels are populated mostly by mummy-themed singing skulls, each rendered with real character and personality, chanting away with an ancient Egyptian musical influence rather than a generic backing track. The whole scene plays out in a radiant, cartoon-style tomb, laid out across a sideways-oriented grid using 99 ways to win, where symbols connect from the bottom upward rather than the more common left-to-right format.

An exploding avalanche mechanic sits at the heart of the gameplay: winning symbols explode and are replaced by new ones dropping from above, with each avalanche pushing a rising multiplier higher, up to 32x in the base game or 64x during the bonus round. The multiplier resets between rounds, and avalanches keep chaining for as long as new wins or wilds keep appearing. An Exploding Wild symbol adds further volatility to the mix during these sequences.

What the RTP Means for You

Tutan Kha-boom returns to players at 94.71%, a figure that sits a touch below the broader slots market average. That's a fairly common trade-off for a high-volatility, cascade-heavy release with a rising multiplier mechanic, so it's worth going in aware that the everyday payback is more modest than some competing titles.

Volatility Explained

This is a High volatility slot, and combined with the escalating multiplier system, players should expect real peaks and troughs across a session — quieter stretches punctuated by chains of avalanches that can push the multiplier, and the win, dramatically higher. No specific hit frequency figure has been published, so treat the volatility rating as the main guide to pacing.

Max Win Potential and Stakes

The maximum win on Tutan Kha-boom sits at 5,000x the stake. Stakes run from £/€0.10 up to £/€100 per spin, with Bet+ ante bet options and a feature buy also available for players who want to adjust their odds of reaching the free spins round.

Six pay symbols make up the paytable, all singing skulls in various colours plus a Cleopatra-style character, paying between 0.7x and 5x the stake for five matching symbols.

Verdict

Tutan Kha-boom takes a proven, much-loved Thunderkick formula and gives it a fresh Egyptian coat of paint, backed by a rising multiplier system that can turn a quiet session into a big one very quickly. With a below-average 94.71% RTP offset by high volatility and a 5,000x ceiling, it's best suited to players chasing bigger swings rather than steady returns.
