Super TTT app for iPhone and iPad

Super Tic-Tac-Toe is a 2 player game of skill and strategy. There are 9 Tic-Tac-Toe boards arranged in a 3 x 3 grid. The player who makes the first move of the game can make a move in any board. All moves afterwards must be made in the board corresponding to the square of the previous move. For example, if a player makes a move in the bottom right square of a Tic-Tac-Toe board, then the other players next move must be in the bottom right board. If a player cannot make a move because the indicated board is full, then that player may make a move in any board. The game is won when a player wins three Tic-Tac-Toe boards either horizontally, vertically, or diagonally.
