If you're like me, you spend a fair bit of time online, you like words, and you're enjoy competing against the clock. And if you like puzzles, all the better then! I'd suggest checking out this site called Jumble Word Vault and play along. There's a new puzzle every day.
One bit of advice for speedier play: Don't use your mouse to click the letters. Typing them in makes for faster time and a better score.
