Book of Claws

Book of Claws is the latest mythic slot from Clawbuster, a studio that blends Norse mythology with modern casino action. Instead of generic Viking symbols, the game loads its reels with claw marks, runes, and the ever-present Book of Claws itself—an ancient tome that triggers free spins when three or more land anywhere on the grid. Each free-spin round stacks a random power-up (multiplier, wild claw, or instant cash) so the bonus keeps evolving even after the initial trigger.

If you love high-RTP slots with cascading reels and a Viking soundtrack, Book of Claws delivers. Clawbuster built the game on an HTML5 engine, so it runs smoothly on desktop and mobile, letting you spin while you’re on the train or between live matches. Because the free-spin meter resets only after a full set of symbols is cleared, one lucky trigger can snowball into dozens of extra spins—perfect for chasing that big payout during the next UEFA Champions League break.

Drop your stake on Book of Claws inside any regulated online casino that lists Clawbuster titles, then watch the runes unlock. The game’s volatility sits in the mid-range, giving frequent small wins plus the occasional six-figure haul when the Book of Claws lands stacked across all five reels. Set your bet size, enable autoplay, and let the Norse gods decide—just remember to claim any wins before the next round of qualifying fixtures starts.
