Enter your letters tiles and up to two '?' as wildcards to find all the possible words that match your tiles.
Scramble games are typically those that take letters, scramble them up and then ask you to make some sort of word out of them. They typically require you to reorganize those letters to also answer a riddle or question. This is great in a number of ways because it challenges you to find a valid answer to the question, and also to recognize the correct word or words that the jumble spells out.
This offers you a good way to strengthen your word game play. Scrabble® and Words with Friends® enthusiasts are well advised to do a bit of jumble solving each day, or at least consider them as a sort of gaming tool.
