Auto-daub marks a called number on your cards the instant it's called — no tapping, no watching closely to catch it in time.
Do I need to turn it on?
No. It's on for every card, in every room, for every player — there's no manual marking mode and nothing to switch. Just watch the calls come in and let your cards keep up on their own.
Does it affect my odds?
No. A pattern win is decided purely by comparing your card against the numbers already called in that round — a daub mark is just how that looks on screen, it never changes what wins.
Will I miss a number if I look away?
No — see what happens if I disconnect for why stepping away doesn't cost you anything.
