Blindfold 3-D Tic Tac Toe app for iPhone and iPad

Blindfold 3-D Tic Tac Toe is a fully accessible puzzle, for both sighted and visually impaired people, designed for rapid audio play.

This game was suggested by a teacher for visually impaired students who noticed that blind people do far better at mental 3-D tic tac toe than do sighted people.

3D Tic Tac Toe, is an abstract strategy board game for two players. It is similar in concept to traditional tic-tac-toe but is played on 3 levels: top, middle and bottom. The objective of the game is to be the first player to form a horizontal, vertical, or diagonal line of three checkers on one level, or across three levels.

The game comes with coins; you need one coin to play. More coins are available as an in-app upgrade.
