Review
Book of Dino Deluxe is a prehistoric adventure slot from Swintt, played on a 5×3 grid with 5 fixed paylines. The game offers a base RTP of 96.01% and features high volatility, making it suitable for players seeking high-risk, high-reward gameplay.
Base Gameplay
5 fixed paylines
The “Book” symbol acts as both Wild (substitutes for other symbols) and Scatter (can pay alone and trigger bonus rounds)
Bets typically range from 0.10 up to the maximum allowed by the casino
Special Features
Free Spins with Expanding Symbol: Landing 3 or more Book symbols triggers 10 free spins. Before the free spins start, a “Lucky Symbol” is randomly chosen. During the free spins, this symbol expands to cover an entire reel when part of a winning combination.
Retriggers: If 3 or more Book symbols appear again during the free spins, additional free spins are awarded and a new expanding symbol is selected, increasing win potential.
Bonus Options: Some versions allow an “Increase Feature Chance” option to improve the likelihood of entering free spins, or a “Buy Feature” to access the free spins directly.
Win Potential & Volatility
The maximum win can reach up to 6,000× the bet. High volatility means that large wins occur less frequently, but they are highly impactful when they do.
Book of Dino Deluxe combines the classic “Book” slot mechanics with prehistoric-themed visuals, dynamic expanding symbols, retriggers, and modern risk-control options, making it appealing to both traditional and high-stakes players.
