Tic-Tac-Toe

Just like the traditional pen and paper game, this is played with either 2 players or teams and the aim is to get either 3 Xs or Os in a row, either horizontally, vertically or diagonally.  To start, 2 tic-tac-toe boards are drawn on the scoreboard, 1 for each player or team, as well as one larger board for the actual game.  A player/team has to close, ie. score 3 of a number, in order to get an X or O on the game board.  In this game, the thin outer ring counts as 2 (a double) and the thin inner ring as 3 (a triple).  Once a number has been closed it no longer counts for the other player/team.  Players take it in turns to throw and the winner is the first to get a tic-tac-toe.
