How do Romans play tic tac toe?

Romans played a version of tic-tac-toe using a grid similar to the modern 3x3 layout, but they often used different symbols or shapes instead of Xs and Os. The game was called "Terni Lapilli," where players would place their pieces on the grid and try to align three in a row. Unlike the modern version, players typically had a limited number of pieces and would not place them on the board in a turn-based manner; instead, they would move their pieces strategically during the game. This ancient game showcased similar strategic thinking and competition as today's tic-tac-toe.
