3. Players decide who begins the game by rolling a die.

1. Players take turns to place a BEAD on the board.

2. Players try and create a row of 3 BEADs either horizontally, vertically or diagonally.

3. Players continue to take turns until a player has created a row of 3 beads or there are no more spaces available on the board.

4. To make the game more challenging, players can use a 4-by-4 or a 6-by-6 grid pattern and try and make a line 4 BEADs long.

1. To win the game, a player must create a line of 3 BEADs wins.

2. The game is a tie if there are no more spaces on the board and no player has made a line of 3 BEADs.

1. An early variant of Tic-tac-toe was played in the Roman Empire, around the first century BC. It was called Terni Lapilli and instead of having any number of pieces, each player only had three, thus they had to move them around to empty spaces to keep playing. The game's grid markings have been found chalked all over Rome.

2. Another closely related ancient game is Three Men's Morris which is also played on a simple grid and requires three pieces in a row to finish.
