Eclipse Tic·Tac·Toe Game

This FREE application is our version of the classic children's game using space and Earth science as the basis for its questions and answers. 2 players can challenge each other, or 1 person can play solo, against the computer.

You can edit any question set or even create your own by purchasing the Tic·Tac·Toe Editor, which allows you to completely control the content of any game question set.

The basic installation comes with the Tic·Tac·Toe game and Editor (which runs as a 30 day demo before requiring purchased registration), and a default sample game dataset. You will need to download the game AND the Eclipse data set to play the Eclipse game.

NOTE: The resolution of the game display is 1920x1080. It is not resizable.

Tic·Tac·Toe is available for Mac OS X (10.7-10.14) and Windows (7-11)
