Same 24 things for everyone, shuffled onto your own card. Stamp what you actually see or hear tonight. Prizes are drawn at random from everyone who registers - lines are for bragging rights.
No bingo call yet. Stamp five in a line and the button lights up.
Everyone who registers gets one free entry. The draw does not look at lines, calls or how fast you played.
