A simple game of fundamental logic, Mastermind will have you deducing the sequence of four colored pegs that are hidden from your view. The set can be ordered in any way (including all four the same color), and you'll have to figure out the combination based on scoring pegs that tell you only how many correct-color pegs you have in the right position and how many correct-color pegs are misplaced. If you can uncover the sequence through trial and error in 10 chances, you win. In addition to the classic game, you'll also get rule variants, including side-to-side and head-to-head, where players race against each other, trying to be the first to unlock the code.
