Marupeke

Marupeke is a logic puzzle based on the principle of Tic-Tac-Toe, but avoiding making lines of three noughts or three crosses. We present the solver with a grid of squares, some of which are filled, and some of which already contain a nought (0) or a cross (X).

The solver’s challenge is to place a 0 or X in each of the empty squares so that no lines of three noughts or three crosses are created in any direction, including diagonally.

We can create this puzzle at different levels of difficulty to suit the audience. It is closely related to Noughts And Crosses.
