Borrowing elements of the tabletop classic Reversi (a.k.a. "Othello") and the primordial computer game Snakes, this action-puzzle is played on a board that contains an arrangement of black-and-white squares. Each square is black on one side and white on the other, and the object in each level is to flip some of them over so that they all match. Squares are flipped by drawing a line through them, but to "win," the player can only draw a single line in each level (hence the game's original working title, "One Line Puzzle"). Timed, strategic, and wireless two-person competitive modes of play are offered.
