This project is an easy print. The hardest part is changing filaments: you need a set of nine markers in two different colors (e.g. red and blue), three of each kind. The markers can be stored in the box (e.g. white, gray or any other color you like). The cover can be used as a playing field.

Game Rules

Similar to traditional Tic-Tac-Toe, the goal of this game is to place three of your markers in a single line: horizontally, vertically, or diagonally.

Each player receives three each of the large, medium, and small markers.

The players take turns placing a marker into a space. A player can place any size marker in an empty space. If a space is occupied, a player can only add a marker if the new marker is larger than the present marker.

For example: if a space contains a small marker, you can place a medium or large marker. If you place a medium marker, your opponent can potentially steal that space by placing a large marker. If you place a large marker, that space belongs to you and cannot be stolen.
