#Ultimate Tic Tac Toe

##The Game and Rules

The game is a modification of the classic game Tic-Tac-Toe. The original game, if played optimally, always ends in a tie game. Not so interesting. The basic modification is that the playing grid is now a 3x3 grid which contains a mini-3x3 grid inside each cell.
A cell is claimed by a player as his if he wins the mini-3x3 grid contained in it. But the cell in which a player can play is not decided by him, but by the move his opponent makes.
This makes the game unpredictable and complicated. A detailed description of the complete rules is available on
