Easy points:
When there are multiple pairs of the same card, valuematch them back-to-back to get 2,500 bonus points.
Remove all of the cards from the level and from the card pile for 10,000 points.
Power-up cards:
Using the Power-Up cards correctly is required for getting off the island. The Magnets can pull any card to the position of the magnet, even if the cards are covered by other cards. The Key can remove any visible Lock (even when partially covered by other cards). The Jokers remove all of the remaining cards of the same card you click on, but only work on face-up cards.
Clues:
To unlock clues, find the hidden objects underwater and on land. A keen eye and patience are required to find them. However there is no time limit and you have unlimited “hints”.
