Push through the overgrown temple where dinosaurs guard the relics and a single book unlocks the vault. Your job is to find it: land 3 or more Book symbols anywhere on the reels and 10 Free Spins begin. One symbol is chosen at random to expand across entire reels and pay without needing to touch. Those spins retrigger every time 3 more Books appear, stacking round after round with no upper limit. Book Of Dino Unlimited is a medium volatility, fixed paylines slot from SwinttPremium. Matching symbols pay across 5 reels and 3 rows, from left to right starting on the first reel. The Book symbol acts as both Wild and Scatter, substituting for all regular symbols and triggering the Free Spins bonus. Fill the screen with the top premium symbol in the bonus round and wins can reach 5,000x your stake. Here is how you play.
