I have won tons of games with this descrambler, you can improve you vocab (somehow) and your own ability to find good words. Only on one though, if you enter a wild letter, when they descramble the words, 1: You get confused b/c you dont know which one is the wild, and 2: They count the points as their normal points, but in Scrabble wild does not worth anything.
Maybe also add a feature so that we can exchange wilds already on board for corresponding letter in your letters, so that we reuse them.
