A fully-functional game of Mastermind written in Perl.


Consult the Mastermind Instructions if you are unfamiliar with how the original game is played. This demonstration shows how my script is used to play the game:


perl mind.pl


1 1234


Program prompts with '1', which indicates the first guess. Player guesses '1234'.




Program responds with 1 white peg and no red pegs.


2 5678



8 8822

0W4R 8822


4 red pegs followed by the answer shows the player guessed the code correctly before his ten tries were exceeded.



sub q{$;=1;$q='';$q.=int(rand(9))for(5..8)}sub _{print@_}&q;for(;;){$:=$~=0;_
"$/$; ";chop($_=<>);if(/^d{4}$/){$_.=q,_._,.$q;$:++while+s/(.)(.{6})1/;$2,/
;$~++while+s/(.)(...+)1/;$2$1/;_"$~W$:R ";++$;;$:==4|$;>10&&_($q)&&&q}}
