Book of Toro Slot Review

ELK Studios took their cartoon fighting bull from Wild Toro and dropped him into an Egyptian tomb. The result is a 5x3 grid with ten fixed paylines that runs on the familiar expanding-symbol formula. Released on 2 November 2021, it throws card royals and mummies together in a weird but fun mix.

You get an RTP of 95%, a ceiling of 10,000x your bet, and volatility running at seven out of ten. The draw here is that the bull brings his own mechanics with him. He walks across the reels leaving wilds behind, sitting right on top of the standard book structure.

The base game is mostly a grind. Wins pay left to right from reel one, and the game pays something on roughly one spin in four. Full screens of card royals with no feature symbol anywhere in sight are the normal state of it, and the balance ticks quietly down while you wait for one.

Top and mid symbols pay from just two in a row, but they return very little. Everything else needs three, and with no cascades or multiplier trails, you really feel the empty spins.

Toro only lands on reel five, stepping one reel left at a time. Every step gives you a free respin, turning a single bull into up to five respins with a wild moving across the board. The real action happens when he meets the mummies. Mummies lock into place for their own respins, but if a Toro is on screen with them, the Toro Goes Wild feature takes over.

The bull charges vertically and horizontally to knock the mummies off the grid, leaving a wild symbol on every square he clears. Books stay sticky while the bull is walking, making a long charge a great way to collect bonus triggers.

Landing three books gets you 10 free spins, four give 15, and five give 20. The game picks one random symbol to expand, which completely decides if the round is worth your time. The best design choice ELK made here is how the bull interacts with the bonus.

The free spin counter actually pauses the second a Toro lands or a mummy respin starts. You get to play out the whole chain of respins without burning a single free spin, and the expanding symbol stays active the whole time. You can also retrigger the round by landing three more books, adding spins and extra expanding symbols up to a cap of three.

There are five X-iter buy tiers, and surprisingly, they all run at the same 95% RTP as the base game. Ten times your stake buys a guaranteed mummy respin, while 25x buys a Toro drop with sticky books. Fifty gets you a Mini Bonus of three spins, and 100x buys straight entry to the free spins.

The 500x Super Bonus is the only one that changes the math. It adds a progressive multiplier that climbs with every free spin and respin. Since Toro's walk and the mummy chains push the multiplier up, the respins become the main engine for massive payouts.

The artwork is bright and the bug-eyed mummy gets a laugh, but the base game is just too quiet to recommend playing this the traditional way. Most of the base game is clicking through dead screens of card royals waiting for the bull to show up. That 10,000x top prize is practically decoration unless you pay for the 500x Super Bonus, because the progressive multiplier does not exist anywhere else.

The charging bull mechanic is genuinely fun, and pausing the free spins during respins is a great touch. If you want to see the bull do his thing, it is worth spending 25x on a guaranteed Toro. Otherwise, we would skip grinding the base game for a bonus you might never hit.
