Jurassic Island

The Jurassic Island slot machine invites you to go back to the time when the dinosaurs lived. This is a historical slot developed by Playtech. It has 5 reels and 25 paylines. One spin can bring the payouts with the coefficients of up to 1,000. A dinosaur hunter is the scatter. It opens access to 4 bonus games in the slot.


Rules of Jurassic Island Slot

The number of paylines is fixed. At any time of the game, all 25 of them are used. Players can change the bet value on the line. It is regulated in the Line Bet menu with the buttons “+” and “−” and can be from 0.01 to 5 credits. The Total Bet window shows the size of the total bet. The Spin button starts the reels in the manual mode. The Auto Play key activates the automatic mode of the game. The Turbo key on the control panel speeds up the spinning of the reels. To open the paytable, use the Info button.

Winnings are accrued when there are at least 2 or 3 identical icons on the payline. For not identical symbols, the number in the combination is different. You can get information about it in the payout table. The combinations are formed from the first reel from left to right. There is no risk game or progressive jackpot in the gameplay.

Symbols and Coefficients

The dinosaur is a wild symbol. It can replace all the icons except for the bonus ones in the prize combinations. The wild symbol expands to the entire reel provided that it leads to the formation of a winning combination. It appears only on three middle reels and does not bring paid combinations by itself. The green dinosaur symbol has the largest payout coefficients (of up to 1,000). Lizards of purple and blue colors bring the winnings with the multipliers from 5 to 300. Symbols with a pterodactyl and dinosaur’s skull give the sums with the coefficients from 10 to 150. The card icons are designed in the form of bones and have multipliers from 5 to 100.

Bonuses of Jurassic Island Slot

When there are at least 3 symbols with a portrait of a dinosaur hunter anywhere on the reels, you can get access to one of the four prize rounds:

  • Multiplier Free Games
  • Carnivore Free Games
  • Raptor Free Games
  • Hot Shot Hunter Bonus

Players select the type of the bonus game independently. During the Multiplier Free Games round, you can get from 10 to 30 free spins. During free spins, all payments are tripled. The Carnivore Free Games round gives the same amount of free spins. During them, only the dinosaur symbols appear on the reels.

The Raptor Free Games round gives from 16 to 40 free spins according to the rules that are in effect during the regular spins. Hot Shot Hunter Bonus is a separate mini-game. During the game, you will hunt the dinosaurs. Each type of the dinosaur has its own prize multipliers:

  • Pterodactyl – from 3 to 50
  • White dinosaur – from 6 to 180
  • Green dinosaur – from 3 to 120

How to Win Jurassic Island Slot

The theoretical return rate is 96.5%. Since the number of active lines is fixed, your influence on the probability of winning is minimal. However, if you want, you can gradually raise the bet until the combination of scatters appears. During the bonus games, the largest payouts are possible.
