Book of Jurassic online slot
Fans of literary-style slots and dinosaur themes can add Book of Jurassic to a casino lobby of familiar favourites. This 5x3, 10-pay-line video slot pays for dinosaur combinations, while scatters appearing anywhere on the reels can activate spin bet multipliers and a free spins bonus. That bonus includes an expanding symbol that pays anywhere.
Theme and storyline
Book of Jurassic places you alongside a fearsome explorer who opens a relic book of dinosaurs, sending you back to an age when the creatures ruled Earth. Within this Jurassic wilderness, the reels feature a T-Rex, Triceratops and a Theropod.
Graphics, sound and animation
Book of Jurassic delivers a vivid presentation on mobile and/or desktop, with Amigo Gaming responsible for the slot's graphics. Detailed artwork, fluid animation and a generous palette sit against a rich red backdrop, while the straightforward interface keeps navigation simple. A gently pulsing theme tune complements the gameplay sound effects rather than competing with them. In this GCCans review, Evan Carrington finds the Book of Jurassic online slot's visuals, audio and animation worthy of an enthusiastic double thumbs up.

Gameplay
Amigo Gaming builds the game around 5 reels with 3 positions on each and the familiar 10 pay lines found in many book-themed slots. Book of Jurassic's reels contain 10 symbols: 4 high-paying pictures and 5 lower-paying playing cards. The central reel symbol is the ‘Book of Dinosaurs’. It unlocks scatter multipliers and the free spins bonus, while also acting as a wild that substitutes for the 9 regular symbols.
When the scatter appears anywhere on the reels 3, 4 or 5 times, it awards a spin bet multiplier of 2x, 20x or 200x, respectively. A regular symbol pays when 3, 4 or 5 appear along one of the slot's 10 pay lines, beginning with the first symbol on reel 1 and continuing across adjacent reels towards the right.
Spin bet multiplier payouts for 5-symbols on a left-to-right pay line:
- Book Dinosaurs (Scatter) – 200x
- The Explorer - 50x
- T-Rex – 20x
- Triceratops – 7.5x
- Theropod – 7.5x
- A or K symbols – 1.5x
- Q, J or 10 symbols – 1x

Bonuses and free spins
Free Spins Bonus: Landing 3+ ‘Book of Dinosaur’ scatters awards 10 free spins.
Expanding Symbol: Any regular symbol may randomly turn into an expanding symbol. Whenever it lands on the reels, it grows to occupy all positions on the reels. During the Book of Dinosaur’s free spins game, the expanding symbol does not have to land on adjacent reels to form a combination because the feature uses ‘Pay Anywhere’.
Bet sizes, RTP and variance
Min-max wagers run from 0.10 to 100.00 per spin. The Book of Jurassic's RTP is not shown in the pay table or elsewhere in the slot's pay table. The review notes that most book slots come with a 96% RTP and consequently describes this as likely to be a high-variance slot; that assessment is not a confirmed game specification.
Conclusion
The review concludes that dinosaur themes, the familiar book symbol and 10 pay lines give Book of Jurassic a clear place among book-themed video slots. If your online casino has a ‘book’ section and carries games from Amigo Games, the title may be another option for that lobby. It includes the usual book-slot features, with a scatter handling three roles: multiplier, bonus trigger and wild symbol. Once the free spins bonus begins, the expanding symbol adds its ‘Pay Anywhere’ feature to the game.
