Nab-It!

Description from BoardgameNews.com:
Nab-It! is reminiscent of the word game Upwords in that players can stack letter tiles on existing letter tiles in order to create new words, but there are three differences: (1) the game includes no board, (2) each player has her own set of tiles in a particular color, and (3) the player who has the highest or most tiles in a word scores one point for that word (no matter how long) once the game ends.
