Each Underwater Treasures game features 5 Bonus meters and either 10 or 20 tickets.
Each ticket can reveal a symbol with a prize amount, a Shell Surprise, or a Sea Creatures symbol.
- Reveal any Fish symbol to win the prize shown on that ticket.
- Reveal a Shell Surprise for a chance to win a surprise amount.
- Reveal a Sea Creatures symbol to fill in 1 space on the appropriate Bonus meter. When all spaces in a Bonus meter are filled, enter the Bonus game for a guaranteed prize.
- The Bonus Game features 7 tubes at the top of the screen. 5 of the tubes display prize factors, one displays an Up Arrow, and one displays an “X”.
- During the Bonus Game, sea creatures will swim towards the top of the screen. If a creature reaches a tube with a prize factor, add that prize factor to your total prize. If a creature reaches the Up Arrow tube, upgrade the prize factor values shown.
- If a creature reaches the X tube, one strike will be collected. After 3 strikes are collected, win the total prize shown and exit the Bonus Game.
