Spinosaurus slot game online
Spinosaurus is an online slot centred on one of the less-celebrated dinosaurs. The game returns players to a world before mankind, where free spins, several wilds and upgraded symbols may appear, though none of these features makes a win certain.
Theme and Storyline
Enter a volcanic prehistoric setting where dinosaurs roam across the reels. The adventure moves through forests, plains and swamps, presenting environments associated with the Spinosaurus along with the creatures that challenge it.
Graphics, Sound and Animation
Booming Games places one of its strongest visual concepts on the reels. On desktop and mobile, players encounter photographic dinosaur symbols, including the feared T-Rex and Velociraptor, alongside fossilised footprints. Subtle animation appears during 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. It does not add dinosaur roars or wildlife ambience in the background.

How the Gameplay Works
Spinosaurus uses a 5-reel layout, with 3 symbol rows on every reel and 20 pay lines for winning combinations. Its wild symbol is the ‘Pterodactyl Egg’, which can appear up to 15 times across the reels. Further wins can come from symbol upgrades, scatter symbols awarding free spins, and ordinary combinations divided into major and minor groups.
The major symbols are Spinosaurus, Tyrannosaurus Rex, Velociraptor and Triceratops. In that order, they pay 50x, 40x, 30x, or 20x the spin bet for 5 symbols on a pay line. They also pay when 5, 4, or 3 combine on a line. The review describes these combination payouts as very generous.
Minor symbols depict fossilised footprints belonging to the dinosaurs listed above, although matching each print to its dinosaur takes some figuring out. They pay between 6.25x and 0.5x the spin bet when 5, 4, or 3 reach a pay line. 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 does not participate in the symbol upgrade feature and cannot act as a wildcard for the scatter symbol.
Open the paytable for the rules on one tab and the individual payouts on the other. The ‘ ’ sign provides access to ‘Bet Max’, auto-spins, lightning spins and sound controls.
Bonuses and Free Spins
Free Spins: Landing 3 volcano scatter symbols on reels 1, 3, and 5 awards 8-12 free spins. Each scatter carries a number showing how many free spins it awards. When only 2 scatter symbols land, they turn into wilds. The drawback is that free spins cannot be re-triggered.
Symbol Upgrade: When this feature activates at random, it changes between 0 and 10 minor symbols into 1 of the major symbols. It can also trigger while 0 symbols are upgraded, leaving the slot to tease you without changing the layout.
Pterodactyl Egg Wild Feature: During either 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
The ‘BET’ -/ option or coins button sets the bet range. A minimum of 20.00 can be wagered per spin, while the maximum is 200.00. The Spinosaurus slot lists an RTP of 95.53%, about half a percent below the average, and the low-variance classification is described as accurate. The reported base-game hit rate is about 1 every 5 spins on average, with high-paying symbols helping combinations cover the spin bet. For larger wins, the review identifies free spins as the key feature, building wins at no additional spin cost before one final payout when the bonus ends.
Conclusion
In the original GCCans review by Evan Carrington, Spinosaurus from Booming Games is presented as a dinosaur-themed slot with scatters, free spins and wilds. The review highlights the substantial values attached to symbol combinations and notes that only 3 combinations pay less than the spin bet. The mechanics are familiar rather than innovative, but the review considers the game accessible for new players and suitable for anyone seeking an easy-to-play mobile slot with attractive graphics that are not hardware intensive.
