[1] The game was designed by Marvin Glass and Associates and created by Hank Kramer, Larry Reiner and Walter Moe, and is now distributed by Mattel.
Players stand approximately six feet from the board to toss their beanbags, alternating turns.
Even if a player succeeds in hitting the square they wish to change, it is often impossible to control the effect one's beanbag impact will have.
Blocks may turn quickly, spinning a few times before coming to rest, at which point any side may be facing up.
With practice, players can become increasingly adept at hitting the precise location on the board that they wish, enabling them a better chance of affecting the square they want to change.
Unlike traditional tic-tac-toe, a letter placed in a given square may not stay there the rest of the game.
This highlights the major game strategy that it is often more effective to attempt to remove opponents' letters than to block them from getting three in a row.
However, in Toss Across, unless Joe is confident he can control his throw to the degree that hitting the bottom center block will definitely change it to an O, this is not the best move.
While no method of tossing the beanbag is guaranteed to have the desired effect, tossing the bag vertically (such that it rotates corner over corner) rather than horizontally (such that it stays mostly flat) tends to create more significant impacts and more often turns the blocks.
