Draft and trade surfboard pieces and attempt to build the tallest and most surfboards. On a turn you take two actions, with three types of actions being possible:
- Add a card from the deck to your personal supply.
- Take a card from your supply to start or lengthen a board; all cards in a board have to be the same color (or wild) and each new card on a board must be equal to or greater in value than the card below it.
- Place one or more cards from your supply in an opponent's supply, then take a single card from their supply of value less than the sum of what you gave them and use this card to start or lengthen a board.
When a player has 3-4 complete boards, at least one of which contains 7+ cards, they can choose to end the game. If that doesn't happen before the deck runs out, the game ends at that point.
Players then score sticker points on completed boards, lose points for incomplete boards, and score bonus points for the longest board or the most boards or for any of the four random objective cards.
