Book of Dino Slot Review
Two long-necked sauropods graze a grassy slope at the edge of the reels while vines wrap the carved stone frame around them, banana fronds spilling in from the right. This is Book of Dino, Swintt‘s take on the book formula, and it’s a stripped-back one: a 5×3 grid with 5 paylines, and a single book symbol working as wild and scatter at once.
The classic book games run ten lines or more, so whether the round still builds its big moments on a fraction of that is the fair question. The jungle around the maths is lush; the maths itself is sparse. It joins Egypt King Multi, Wild Chicken and Champions Of The Spin in the Swintt stable.
5 Paylines and a Familiar Book
Wins pay from the leftmost reel to the right across 5 fixed paylines, and only the highest combination on each line counts. Line wins are added together. It’s an old-fashioned layout, and it means the maths leans heavily on the top of the paytable rather than on a scatter-pays engine.
That structure has consequences for how often anything lands at all. With 5 lines and left-to-right-only wins, most spins are misses, and the royals that fill the middle of the grid rarely add up to much. The book symbol is doing double duty throughout: it’s the wild and the scatter at once, substituting for every symbol except the Lucky Symbol and paying from three of a kind.
Scatters count anywhere on the grid rather than along a line, which is the one place the game breaks its own left-to-right rule. Everything else follows the paylines strictly.
Pays are quoted as multiples of the total bet rather than the line bet, so on a 5-line game the numbers below are the ones you actually receive:
- Male adventurer: 2x for two, 20x for three, 200x for four, 1,000x for five
- Pteranodon: 1x for two, 6x for three, 80x for four, 400x for five
- Yellow dinosaur / Triceratops: 1x for two, 6x for three, 20x for four, 150x for five
- A / K: 1x for three, 8x for four, 30x for five
- Q / J / 10: 1x for three, 5x for four, 20x for five
- Book (wild/scatter): 2x for three, 20x for four, 200x for five
That adventurer is a rich top symbol by the standards of a 5-line game, and the royals are where the smaller wins live without ever paying much. There’s no second tier of premiums to bridge the two ends of the table, so the drop from dinosaurs to letters is steep.
Every value in the game is counted in coins rather than currency, and your credit balance, current bet and recent wins all sit in the one display. The play button can also be triggered with the space bar, and autoplay runs with the usual settings.
Before a run starts, you pick a win limit and a loss limit, and either can be set to 0 to switch it off:
- Win limit: autoplay stops the instant a single win exceeds the value you set
- Loss limit: autoplay stops the instant your balance has dropped by the value you set
- Feature games triggered mid-run don’t interrupt autoplay; it continues once the round finishes
Feature Games and the Lucky Symbol
Land three or more scatter books anywhere and the game awards 10 feature games along with a Lucky Symbol. That’s the whole bonus: the rules state that the wild does not substitute for the Lucky Symbol.
Three books alone are worth 2x the total bet, so the trigger carries a floor of its own. With only 5 paylines in play, the round lives or dies on how the Lucky Symbol lands. The book itself doesn’t substitute for it.
The round can’t be retried through the gamble, either. The Risk Game is switched off entirely while feature games run, so whatever the 10 games pay is what you keep.
Buy Feature Games
A BUY FEATURE GAMES button sits at the bottom left of the base-game screen, and it takes you straight to the 10 feature games plus Lucky Symbol without waiting on the scatter.
Risk Game and Card Risk
After any round win outside autoplay, a Risk button appears. Skip it and you collect; press it and your last win becomes the stake in a red-or-black card gamble. A correct call doubles the bet, a wrong one loses it, and a successful call can be gambled again.
The gamble stakes run from 1 to 50,000 coins, and wins above 50,000 can’t be gambled at all. There’s a hard ceiling of 100,000 coins and a limit of 10 rounds, and each call is a 50/50 shot with no house edge built in. Exceed either limit and the option to bet again disappears.
The gamble isn’t available during feature games, and the cards you see dealt have no bearing on the outcome. The overall return takes the optional gamble into account alongside the reels, so playing it or leaving it alone makes no difference to the game’s payout percentage.
Our Honest Verdict
Overall Rating: 6.3/10
This one demands patience. The jungle around the reels is genuinely lovely, but with 5 lines the spins between wins are quiet ones, and the base game gives you the adventurer to aim at and little else. It’s a game for someone who likes that old book rhythm and wants it dressed in something greener than sand.
The best thing here is the card gamble: a true 50/50 with a 10-round ladder, a 100,000-coin ceiling and no house edge, which is more generous than most slots’ side bets. The worst is that the feature round inherits the line problem – 5 paylines mean the Lucky Symbol either lines up or it doesn’t, so the bonus can just fizzle.
It suits the old-school book crowd who like their reels sparse, and it has little to offer anyone after a busy grid. If 5 paylines is plenty, the dinosaurs are good company.
