Projective Set

Projective Set or ProSet is a real-time game like SET in which you're trying to find groups of cards that go together.

Each card in the deck has 1-6 different symbols on it. Seven cards are dealt onto the table, then players try to find a set of cards ranging from 3-7 cards such that each symbol is present on the selected cards an even number of times. (With seven cards on the table, at least one set is guaranteed to exist.) Whoever first spots a set claims those cards, then you refill the display to seven cards. When the deck is empty and no more sets can be found, whoever has the most cards wins.
