To win the co-operative card game Wave, everyone needs to be surfing in sync.
On your turn, play a card on the common discard pile. This card must be higher than the top card, either with a higher numerical value (number) or with a higher suit (color). The tricky part is that you can see only some of the cards in your hand because some cards face towards your teammates. Therefore, you need the help of your team to choose an appropriate card. At the end of your turn, draw a new card.
If you cannot play a higher card on your turn, the game ends immediately and everyone loses. To win, all players' cards must be played on the discard pile with no cards left in the draw pile.
Wave includes rule variants for experienced players to make the game more challenging.
