First off...My apologies if "Word Search" is the incorrect term for this, I have no clue what the official name for this type of app is. people usually relate it to Scrabble.
Here is my take/idea on making a word search/"Scrabble solver" app that can handle wildcards. I created this a while back, and updated it a bit since then. It is not rapid fast sometimes when looking for 10 or more letters, or when using a lot of wildcards, but i find it pretty fast if using it as you would in any scrabble combination.
If you have a link to one you've created or seen, let me know; i'd like to view the source.
:eek2:Note: This includes a dictionary. The program is built around the current dictionary words in relation to the amount of duplicate letters in a word(maximum 7) and word length(maximum 15).
