American 75-ball, one-line house rules. B: 1–15, I: 16–30, N: 31–45, G: 46–60, O: 61–75. The centre square is free. The first player calls the balls and also has a card. Mark called numbers yourself, then claim any complete row, column or diagonal. The server checks the drawn numbers and your marks; the first valid claim wins. Marking a line alone does not claim it. Claims remain available after all balls are drawn. No money or prizes.

Rooms expire 24 hours after the last action. Refresh to reconnect; leaving ends the current game.
