Slingz

About Slingz, from BoardGameGeek:

Slingz is a dynamic card game in which you're trying to shout out answers faster than ever before. Each player starts with a hand of five letter cards, then you reveal a theme. Think of a word that fits the theme and starts with one of your letters, then sling that card on the table, yelling out the word. As soon as three words have been given, reveal a new theme and switch your brainwaves to the new challenge. The first player to ditch their five letters wins the round.
