You've probably already spotted the icon next to this blurb and thought, "Xs and Os in a grid? Must be Tic Tac Toe... But why haven't they played in the middle square? That's an easy win for both players!" That's true, however it might not be the best strategy in Tic-Tac-Toe-Ception, where the square you make your move in on one grid determines the grid your opponent plays in on a larger meta-grid. A simple game of three-in-a-row just got a whole lot harder!
