This game is inspired by "Brain Training Logic Puzzle"
by CL-Games. You can free download it from the Play Store
and play a lot of addictive puzzles in one game.
About this one puzzle, it is called "Crack Code".
For difficulty level, I added the first question about -
|How many digits you want to try?|
Regarding the insanity, I recommend you playing between 3 to 10 digits.
The information about real passcode leaks after every attempt you make effort.
Green mark - Right number in right place.
Red cross - Right number in wrong place.
Yellow sign - Wrong number and place.
