Terni Lapilli, also known as Rota, is a board game from ancient Rome similar to the modern tic-tac-toe.
I tried to keep the design simple and practical. You can print everything without supports and for "assembly" only a little glue is needed for the magnets. Thanks to the latter, the pieces are kept in place both when playing and when stored (no maracas effect when travelling with the game).
Hope you like it and bonam fortunam!
