Stac-tac-toe is a variation on the traditional tic-tac-toe game. Instead of being able to play into any one of the nine positions, a play must be made into one of the three "columns." The columns may be stacked as high as desired. After all of the beads have been played, then a player can split a substack ( 1 to number in stack) from any stack, and then move that substack of beads to any position. First player to make 3 in a row wins, or play for a score. The beads have a hole in the top and a post sticking out of the bottom. So the beads stack onto the board without the need for a post. The boxed game includes rules, and a board. In addition each player has five "beads" and a peg to keep score. The player colors are yellow and orange. The playing board is black.
