What Is Book of Jurassic?
Book of Jurassic is a book-style adventure slot set in the Jurassic period. You’re an explorer chasing a mystical tome through a lush, dinosaur-filled jungle — a familiar premise, but one Amigo Gaming dresses up with sharp animation and a driving low-frequency soundtrack. The 5×3 grid and 10-payline structure is standard for the genre, and if you’ve played Book of Ra or Book of Dead before, the mechanics will feel immediately familiar.
This game suits players who are comfortable with long dry runs between payouts. High volatility means the reels can go quiet for stretches, then deliver a chunky hit during the free spins bonus. It’s not a pokie for casual players chasing small, steady wins. If you want frequent top-ups, look elsewhere. But if you’re happy to ride out a lean session in pursuit of an expanding symbol that covers every reel, this is your game.
RTP and Volatility
The RTP is 96%. In plain terms: over millions of spins, the game returns $96 for every $100 wagered. Your individual session could look nothing like that — you might double your balance in 20 spins, or grind through 200 without a meaningful win. That’s what high volatility means in practice.
Bring that to a real session: on a $30 budget at $0.10 per spin, you get roughly 300 spins. With high volatility, don’t expect to stay above your starting balance for most of that time. The game rewards patience and enough bankroll to survive until the free spins round fires. Budget accordingly before you start — a $30 session fund can disappear faster here than it would on a medium-volatility pokie.
Betting Range
The minimum bet is $0.10 per spin and the maximum is $100.00, covering a wide range of player budgets. Because the max win is 6,000x your stake, a $0.10 spin gives you a theoretical ceiling of $600, while a $100 spin takes that to $600,000 — though hitting the maximum during a single session is exceptionally rare. Start at $0.10 or $0.20 per spin until you’re comfortable with the rhythm of the game.
How to Play Book of Jurassic — Step by Step
- Open the paytable first by tapping the three-dot menu on the left side of the reels. Check which symbols pay the most — in this game, the explorer character and the T-Rex top the chart.
- Set your bet using the stake button at the bottom of the screen. Use the plus and minus controls to adjust. Stick to the lower end of the range until you understand how often the free spins trigger.
- Press the main spin button to play one round at a time, or activate autoplay using the circular arrows button. Turbo mode (the lightning bolt) speeds up each round.
- Wins are paid when three or more matching symbols land left-to-right on one of the 10 fixed paylines, starting from reel one.
- The free spins bonus triggers when three or more Book symbols land anywhere on the reels in a single spin. You receive 10 free spins and a randomly chosen expanding symbol.
- After any win, there is no gamble feature in this game — your payout is credited automatically to your balance.
Try this: Set a session budget of $20 before you open the game, play at $0.10 per spin, and aim for at least one free spins trigger before you decide whether the game is clicking for you.
Symbols and Paytable
Book of Jurassic carries 10 symbols across two tiers. The low-paying group uses standard playing card faces — 10, J, Q, K, and A — which pay between 0.5x and 15x your bet per line for a five-of-a-kind combination.
The high-paying group is where the action is. A pterosaur, triceratops, and T-Rex make up the mid-range premiums, while the main explorer character sits at the top of the regular symbol table. Published paytable values show the explorer paying up to 500x your bet per line for five on a payline — though these are dynamic multipliers, meaning the actual dollar amount scales with your chosen stake.
The Dinosaur Book symbol does double duty. It acts as both the wild and the scatter. As a wild, it substitutes for all other symbols except the special expanding symbol that appears during free spins. As a scatter, landing three or more anywhere on the reels triggers the bonus round. The Book pays up to 200x your bet per line in its own right for five of a kind.
Bonus Features
Free Spins with Expanding Symbol
Three or more Book scatter symbols anywhere on the reels trigger 10 free spins. Before the round begins, the game randomly selects one standard symbol to become the expanding symbol for the entire free spins session — it could be the explorer, the T-Rex, or any other regular symbol from the paytable.
When that chosen symbol lands on the reels during free spins, it expands to fill all three positions on its reel. Critically, wins from the expanding symbol are paid regardless of whether the symbols on adjacent reels are contiguous — it pays across all active paylines as long as matching expanded symbols appear. This is where the 6,000x maximum win becomes a realistic possibility, particularly if the expanding symbol is a high-value character like the explorer and it covers multiple reels simultaneously.
The free spins round does not appear to retrigger from additional Book symbols. Those 10 spins are your window — use them well.
Wild Symbol (Dinosaur Book)
Outside of free spins, the Book symbol substitutes for any other regular symbol to help complete winning combinations across the 10 paylines. It cannot replace the special expanding symbol during the bonus round. Think of it as a standard wild with the added ability to trigger the most important feature in the game.
Developer Background
Amigo Gaming is a Barcelona-based studio founded in 2020. Despite being relatively new, the team is made up of veterans from the broader iGaming industry. The studio has grown quickly, with a portfolio of over 80 HTML5 slot titles certified by GLI and available across more than 30 countries, including New Zealand. Book of Jurassic is one of their more recognisable titles, sitting alongside Voodoo Charms and Book of Zeus in their adventure-themed catalogue.
Is Book of Jurassic Worth Playing?
Pros:
- Solid 96% RTP, sitting at the industry average — not exceptional, but not punishing either.
- Max win of 6,000x stake gives meaningful upside without requiring a progressive jackpot format.
- The expanding symbol mechanic during free spins is genuinely capable of producing large single-round payouts.
- Clean visuals, good animation, and a soundtrack that suits the theme without becoming irritating.
- Available on both desktop and mobile with full feature parity.
Cons:
- High volatility makes it a tough ride on a modest budget — you need enough runway to reach the free spins round.
- Only 10 paylines is on the lower end for a modern 5×3 slot, reducing base game hit frequency.
- No retrigger on free spins means your bonus window is capped at 10 rounds.
- The book-style mechanic is not new — players familiar with Book of Dead or Book of Ra will find nothing surprising here.
Book of Jurassic is a competent, well-presented entry in a crowded genre. If you enjoy book-style slots and you have the bankroll to handle high variance, the 6,000x ceiling and the expanding symbol mechanic give you a genuine reason to load it up. Play it for what it is — a patient, high-risk pokie where the free spins round does the heavy lifting. Don’t expect base game fireworks.
Responsible Gambling
Book of Jurassic uses a certified random number generator (RNG). Every spin outcome is independent and random — no pattern, strategy, or timing can predict or influence the result. Set a firm budget before you play and stop when you reach it. If gambling is causing you concern, contact a responsible gambling support service in your region before continuing.
