Made for lovers of Sudoku and other puzzles.
You are presented with a short quote.
Each letter is substituted with another.
An example would be the letter "A" which is replaced with the letter "Z".
If you guess that "Z" is really the letter "A" all words with letter "Z" will be replaced with a red letter "A".
The keyboard letter for "A" will disappear so that you don't use it again.
You will win when all letters are red.
I average 40 keystrokes per game.
There are 150 puzzles to keep you busy.
A small demo is provided.
