Spinosaurus online slot game
Spinosaurus is an online slot focused on one of the less celebrated dinosaurs. The game takes players back to a world before humans, where Free Spins, several wilds, and upgraded symbols may appear—but none of these features guarantees a win.
Theme and Story
Step into a volcanic prehistoric world where dinosaurs roam across the reels. The adventure spans forests, plains, and swamps, showing environments associated with the Spinosaurus and the creatures it faces.
Graphics, sound and animation
Booming Games brings one of its strongest visual concepts to the reels. On desktop and mobile, players see realistic dinosaur symbols, including the fearsome T-Rex and Velociraptor, alongside fossilized footprints. Subtle animations accompany symbol wins and feature triggers. Spinosaurus continues the prehistoric adventure with a familiar Jurassic Park-style theme tune and sound effects for reel spins and winning combinations. There are no dinosaur roars or wildlife sounds in the background.
Top Casinos to Play Spinosaurus:
How the Gameplay Works
Spinosaurus has 5 reels, each with 3 symbol rows, and 20 paylines for winning combinations. Its wild symbol is the ‘Pterodactyl Egg’, which can appear up to 15 times across the reels. Other ways to win include symbol upgrades, Scatter symbols that award Free Spins, and regular combinations divided into major and minor groups.
Spinosaurus, Tyrannosaurus Rex, Velociraptor, and Triceratops are the top-paying symbols. In that order, 50x, 40x, 30x, or 20x times the spin wager is awarded for 5 matching symbols on a payline. Combinations of 5, 4, or 3 also pay. The review characterizes these combination payouts as especially generous.
Minor symbols show fossilized footprints belonging to the dinosaurs listed above, though it takes some figuring out to match each print to its dinosaur. They pay between 6.25x and 0.5x the spin bet when 5, 4, or 3 land on a payline. Of 24 possible combinations, 19 pay more than the spin bet, 2 pay the same amount, and only 3 pay less.
The ‘Pterodactyl Egg’ wild can replace any of the 4 major or 4 minor symbols. It is not part of the symbol upgrade feature and cannot substitute for the Scatter symbol.

Bonuses and Free Spins
Free Spins: Landing 3 volcano Scatter symbols on reels 1, 3, and 5 awards 8-12 Free Spins. Each Scatter shows how many Free Spins it awards. If only 2 Scatter symbols land, they turn into wilds. One limitation is that Free Spins cannot be retriggered.
Symbol Upgrade: This randomly activated feature transforms between 0 and 10 minor symbols into 1 major symbol. It may also activate while 0 symbols are upgraded, teasing a change without altering the layout.
Pterodactyl Egg Wild Feature: During the base game or Free Spins, the ‘Pterodactyl Egg’ wild can drop onto the reels between 0 and 15 times. If 15 appear, the payout is 125x the spin bet.
Bet Sizes, RTP, and Variance
Use the ‘BET’ -/ option or the coin button to set the bet. The minimum wager is 20.00 per spin and the maximum is 200.00. Spinosaurus lists an RTP of 95.53%, about half a percent below average, and the review says its low-variance classification seems accurate. The reported base-game hit rate averages about 1 in every 5 spins, with high-paying symbols helping combinations cover the spin bet. For larger wins, the review points to Free Spins, which can build winnings without an additional spin cost before a final payout when the bonus ends.
Conclusion
In Evan Carrington’s Al Buraq Regina review, Spinosaurus by Booming Games is presented as a dinosaur-themed slot with Scatters, Free Spins, and wilds. The review highlights the substantial values assigned to symbol combinations and notes that only 3 combinations pay less than the spin bet. The mechanics are familiar rather than innovative, but the game is considered accessible to new players and suitable for anyone looking for an easy-to-play mobile slot with attractive, lightweight graphics.
