Grid Control app for iPhone and iPad

A 4x4 Tic Tac Toe game with a twist: you cant 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.
