In the display below each of the three the text input fields, the result of the match is shown. The match is given by black and red text placed between two green arrows. The matched text is in red, the unmatched portions in black, and the backreferences (things matched by ()'s) are given below it. You must match both the pattern and the backreferences to score.
Scoring is as follows: 10 points for each pattern matched, 5 points if your pattern is longer than the hidden pattern string, 12 points if it is shorter. There should be enough patterns here for you to play the game several times without annoying repitition.
It is my dream (fantasy) that this game will catch on, and internet web-zines for computer types will have a regex puzzle section similar to crossword puzzles in paper newspapers. Probably not. In any event, an editor for building the appropriate name/value tags for the ReGame applet (so that you can make your own regex puzzles) will be provided with a registered version of this package.
