About

Colors Seek

Features
Read full description

ColorsSeek is a minimalist version of the classic, challenging and fun board game Mastermind. You must guess a secret combination of four pegs, taken from a set of six different colors.  The order of the pegs is taken into consideration and colors can be repeated.  You have ten attempts to guess the secret combination and each attempt is answered with zero or as many solid dots as correct color pegs you have hit in the correct position and zero or as many unfilled dots as correct color pegs you have succeeded in an incorrect position.  The game ends when you hit the four correct color pegs in the correct position or when you run the tenth attempt.  Each peg, depending on its color, has inner patterns that do not influence the game, but help colorblind people to differentiate each color.  Enjoy your game and improve your mental abilities.
