The rules
Each of two players make up a sequence of four unique
digits. The players then compete in trying to guess
eachother's sequence.
In response to a guess one tells
the opponent how many digits are in the right place
and how many are in the wrong place. For each
digit in the right place one gives an H (hit) and for each
digit in the wrong place one gives a T (touch).
So if you play aginst the computer and your sequence
is 0627 and the computer guesses 2690 then the result you
give the computer is HTT. You also make your guess, for example
1234, on the sequence the computer is "thinking" of. See the
example below.
