Cypher

A code-breaking puzzle. The computer hides a code of six pegs, each one of eight colours, and a colour may appear more than once. You have twelve turns to guess it. After each guess the key pegs say how close you are: a black key for each peg of the right colour in the right place, and a white key for each other peg of a right colour in the wrong place. The keys don't say which pegs they belong to. Each new row starts as a copy of your last guess, so you change only what you want, and each colour plays its own note. You can give up and see the code. Break it to see YOU WON with the number of moves, or run out of turns and YOU LOSE. Your best game is kept.

Controls: Use either controller. Push left or right to pick a hole and up or down to change its colour; press the left button to enter the guess, and the right button twice to give up. On the title, up and down choose and a button starts.
