how to play

the board

• in ultimate tic tac toe there are 9 small tic tac toe boards and 1 large tic tac toe board
• the large tic tac toe board is made up of the 9 small ones
• to win a player has to win 3 of the small tic tac toe boards in a row, column, or diagonal

moving

• where a player can move in a turn is dictated by where the player in the last turn moved
• the player whose turn it is must move in the tic tac toe board in the same position on the large board as the position on the small board where the last move was made
• if we call each small tic tac toe board A-I and each square in a small tic tac toe board 1-9 then if player 1 moves in E-1, player 2 will have to move in A

• if player 2 then moves in A-3, player 1 will have to move in C

• if a player takes a small board the next player can move anywhere, they are not restricted by the rule above

• if the previous move would force the current player to move in a small board that is taken they can also move anywhere
