The playing board consists of nine individual games of Tic Tac Toe which are played with small cards. However, each of these nine games is in itself a square within one Master Game. Thus, when a player wins an individual game, he or she will also be winning one of the large squares in the 10th or Master Game. In Tic Tac Toe Times 10 each cell of the 3x3 grid of the master-game is broken into a 3x3 grid for a mini-game of Tic-Tac-Toe. You play each mini-game of Tic-Tac-Toe normally to try and win that cell in the Master grid. There is a twist to normal Tic-Tac-Toe play however. The first player can place their piece in any of the 91 min-board squares on the board. After that each player must move to the mini-game which their opponent sends them. So if the first player plays in the top right square of one of the 9 mini-games, then the opponent must play their move in the minigame in the top right Master cell. Subsequent play follows the same rule. There are two exceptions to this however for which you get an open turn and you may place your piece on any tile you like. Your opponent sends you to a tile that has already been won (either by you or them). Your opponent sends you to a tile which is full, and hence a tie. Winning Condition The first player to win 3 cells in a row in the Master game wins. Contents: Playing board 39 small "X" 39 small "O" 9 large "X" 9 Large "O" (Instructions printed in boxtop)
