Ruckus and Pile It are the two curent card games offered by Funstreet Games. Both games involve simultaneous play by all players.

In Ruckus, you keep getting new cards. Whenever you see a pile that matches your card, you slam the card down and take the pile. The last to do this will end up with the pile, but if someone goes out of cards first, you may get stuck having never used the card. Sounds violent.

In Pile-It, each player has to sort and stack their cards in three different ways as quickly as possible. Sounds like an aptitude test.
