Snorkel

From BoardGameGeek:

Swimmers compete to collect the most sets of beautiful sea creatures as they snorkel. Snorkel is a family card game that combines memory and set collection to create an easy to learn and engaging game. There is a 3x3 grid of sea cards set in the middle of the table. On a players turn they flip over three cards and try to create sets, a set is three cards with something in common or three cards with absolutely nothing in common. For each set created players get to keep 1 card. The remaining cards are flipped back over and the taken players replaced from the deck. Ultimately players are trying to create sets from the cards they have collected. The game ends when there is only 3 cards left in the grid. The player who has created the most sets wins.
