About

Grid Control

Features
Read full description

A 4x4 Tic Tac Toe game with a twist: you can't move in the same row or column as the previous move made by the opponent. Features: - Single Player: Face against a skilled artificial intelligence across 8 difficulty levels. One must learn to master Control of the Grid in order to defeat all 8 levels and the difficulty automatically adjusts based on your win/lose results. - Local Multiplayer: Challenge an in-person friend by playing a friendly match on the same device. - Online Multiplayer: Face an opponent that could be anywhere else in the world and see who has better control of the grid. Matches are based on a first-come first-serve basis at this point.
