How to Play:

When the game loads for the first time a screen will appear detailing some of the slot’s special features. Press Continue to go to the main screen. Check Don’t Show Next Time if you would like to skip this screen the next time you load the game.

  • Choose the Line Bet by using the +/- buttons on the bottom of the screen.

  • Select Auto Play if you would like to set a number of spins to be played through automatically. You can exit from Auto Play by clicking the Stop Auto Play button (replaces Spin).
  • Click Turbo Mode if you would like to speed up the animations when you spin the reels.

Please note:

  • The slot is played with 25 fixed paylines. Therefore, the Total Bet is calculated as Line Bet x 25.
  • Winning combinations of symbols will be highlighted on the reels after a spin. You can view the payouts for all winning combinations by clicking the Info button. All payouts are multiplied by the Line Bet.

Info Pages:

Click on Info to launch a screen showing the slot’s reference pages, which include all payouts for the main game and information on special features. You can use the arrows on the bottom right to navigate through the pages. Click on the X button to exit and go back to the reels. Descriptions of the Info Pages are provided below:

Paytable (Low Wins) – shows the payouts for the Low Paying Symbols.

Paytable (High Wins) – shows the payouts for the High Paying Symbols.

Special Symbols – explains the behaviour of Scatter and Wild Symbols.

Free Games – provides a description of the three Free Games Bonus Features.

Hot Shot Hunter Bonus – explains the rules and awards for the Hot Shot Hunter Bonus.

Paylines – displays the positions of all 25 paylines as they appear on the reels.

Paylines:

Jurassic Island slot is played using 25 fixed paylines. These are the directions that matching symbols must follow across the reels to record Line Wins.

Please be aware that the Line Bet and Total Bet are not the same. The Line Bet is the stake made on each of the paylines. The Total Bet is the stake made on all paylines added together, i.e. 25 x Line Bet.

About Payouts:

A complete list of payouts for the main game is found on the Paytable Info Pages. The figures shown for each winning combination are multiplied by the Line Bet.

A Line Win consists of a group of matching symbols working left to right in a chain on one of the paylines.

If more than one winning combination occurs on a single payline, you will be paid for the highest value combination only. Wins on different paylines are added up and paid out as a total win.

Wild Symbols:

Wild Symbols can fall on Reels 2, 3 and 4 only. They do not have a separate payout value. Instead, they can substitute for all other symbols (except Scatter) to make the highest paying combination on a payline.

In addition, the Wild Symbols will expand to cover the entire reel when a winning combination is possible. This can happen simultaneously over all three reels that Wild Symbols appear on.

Scatter Symbols:

Scatter Symbols can fall on any of the five reels. They do not have a payout value. However, you will be awarded Free Games or the Hot Shot Hunter Bonus if three or more land on any position on the reels.

Scatter Symbols do not need to fall on paylines or be in any order to be active in the game.

Free Games/Hot Shot Hunter Bonus:

When three or more Scatter Symbols appear on the reels after a spin, you will be taken to the Feature Picking Round to choose one of four bonus features:

  • Multiplier Free Games.
  • Carnivore Free Games.
