Tri-o Tri-x is a game of Tic-Tac-Toe on nine different boards. In the first round, participants place their tokens (either x's or o's) on any one of the game boards. When one has three in a row on a 3x3 square, he/she has won that board and places a large 'x' or 'o' token on it. In the second round, players may move their tokens around either within a board or from board to board to try and 'win' more boards. The first to win 3 boards in a row, wins! One of Ravensburger's Traveller-Serie games.
