Marupeke, also known as Japanese Tic-Tac-Toe, is a noughts and crosses logic puzzle where the objective is to fill in each empty cell with either X or O. A Marupke puzzle consists of a square grid in which some of the squares are blacked out.

Some of the remaining squares contain either X or O. To solve each puzzle, you must place either X or O into each of the remaining squares.

No more than two consecutive cells, either horizontally, vertically or diagonally, can contain the same symbol (i. e.

there are never three Xs or three Os in a line in any direction). Each puzzle has a unique solution which does not require any guesswork to achieve.
