You know what this is.

A hidden code is randomly generated and you have eight guesses to figure out what it is. Black pegs indicate a correct symbol in the correct place, white pegs indicate a correct symbol in the wrong place. Symbols can repeat.

Every time you win, more symbols are added to the pool. Good luck.

Controls:

Change symbols: arrow keys/WASD/numpad
Play guess: space/enter/numpad 5
Restart game: press any key

Note: Numpad controls may not work in the browser version.
