Book of Jurassic online slot
Fans of book-style slots and dinosaur themes can add Book of Jurassic to a lobby of familiar favourites. This 5x3 video slot has 10 paylines and pays for dinosaur combinations. Scatters can land anywhere on the reels to award spin-bet multipliers and activate free spins, which include an expanding symbol that pays anywhere.
Theme and Storyline
Book of Jurassic places you beside a daring explorer who opens a relic book of dinosaurs, taking you back to an age when the creatures ruled Earth. The Jurassic wilderness on the reels features a T-Rex, Triceratops and Theropod.
Graphics, sound and animation
Book of Jurassic offers vivid visuals on mobile and desktop, with Amigo Gaming behind the slot’s graphics. Detailed artwork, fluid animation and a rich colour palette sit against a deep red backdrop, while the simple interface makes navigation easy. A gently pulsing theme tune complements the gameplay sound effects without competing with them. In this Casino Ideal review, Evan Carrington gives the slot’s visuals, audio and animation an enthusiastic double thumbs-up.
Gameplay
Amigo Gaming’s game has 5 reels with 3 positions each and the familiar 10 paylines found in many book-themed slots. Book of Jurassic has 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, and acts as a Wild that substitutes for the 9 regular symbols.
When the Scatter lands anywhere on the reels 3, 4 or 5 times, it awards a spin-bet multiplier of 2x, 20x or 200x, respectively. Regular symbols pay when 3, 4 or 5 appear along one of the slot’s 10 paylines, starting with the first symbol on reel 1 and continuing across adjacent reels to the right.
Spin-bet multiplier payouts for 5 symbols on a left-to-right payline:
- 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 or more ‘Book of Dinosaur’ Scatters awards 10 free spins.
Expanding Symbol: Any regular symbol may randomly become an expanding symbol. When it lands on the reels, it expands to cover every position on that reel. During Book of Dinosaur free spins, the expanding symbol does not need to land on adjacent reels to form a combination, because the feature uses ‘Pay Anywhere’.
Bet sizes, RTP and variance
Bets range from 0.10 to 100.00 per spin. Book of Jurassic’s RTP is not shown in the paytable or elsewhere in the game. The review notes that most book slots have an RTP of 96% and therefore suggests this game is likely to have high variance; this is not a confirmed game specification.
Conclusion
The review concludes that its dinosaur theme, familiar Book symbol and 10 paylines make Book of Jurassic a clear choice among book-themed video slots. If your online casino has a ‘book’ section and offers Amigo Games titles, this game could be another option in its lobby. It features familiar book-slot mechanics, with the Scatter serving three roles: multiplier, bonus trigger and Wild. Once free spins begin, the expanding symbol adds its ‘Pay Anywhere’ feature.
