A bingo card can look quiet even when the right number has been called.
B-12 appears on screen, but the matching square stays blank. Is the game waiting for a tap? With auto daub, the game marks matching squares as numbers are called. With manual daub, the player clicks or taps each match. The setting does not change the numbers on the card or the order of calls; it changes who marks the card.

A missed click may leave a manual card looking incomplete until the square is marked. Bingo detection and claim rules can also vary by site, so the daub setting is worth checking before play begins.
What a daub marks
- Daub
A daub is the visible mark placed on a card square, not the number being called. Depending on the game, it may look like a colored fill, a stamp, or a highlight.
- Called number
The number announced or displayed for a turn. A call makes a matching square eligible to mark; the call itself does not change what is printed on the card.
- Eligible square
A square that matches a called number and can be marked under the game’s rules. Its eligibility is the same whether marking happens automatically or by hand.
- Auto daub
A setting that places marks on eligible squares as numbers are called. The card does not gain different numbers; only the marking step happens without a tap.
- Manual daub
A mode in which the player taps or clicks eligible squares to mark them. Games may call this “manual marking” or use another label; more online bingo terms and screen labels can help clarify unfamiliar wording.
Following a call onto the card
Suppose the caller display in a 75-ball game shows B-12. If B-12 appears in the B column of a player’s card, that square matches the call. If it is not on the card, there is nothing to daub. The sequence in which online bingo numbers are called does not depend on the player’s daub setting.
- With auto daub, the game marks the matching B-12 square. The mark may appear as a coloured spot, shaded square, or other visual effect.
- With manual daub, B-12 remains unmarked until the player selects that square. The caller display has still shown B-12; the player is simply responsible for adding the mark.
Switching between these settings changes the marking step, not the numbers printed on the card or the order of the calls. Two players with the same card could therefore see the same B-12 call but temporarily have different-looking cards if one has not marked it yet. When checking what happened, it helps to compare the called number with the printed square first, then look for the daub.
Manual daub: following each call
In manual play, a call is a prompt to check the card, not a mark that appears on it. When B-12 is announced, the player looks for 12 in the B column and selects that square if it is present. If several cards are open, the same check has to happen on each one: a match on one card does not mark a match on another.
The pace can feel different when calls arrive close together. A player may hear a number, start scanning one card, and move to the next while the following call is already being announced. A called number can therefore remain unmarked even though it is printed on a card. The card still shows the number; it simply lacks the daub that would make the match easy to spot.
Manual selection also leaves room for a slip, such as tapping the square next to the intended match or marking a similar-looking number. In rooms that allow a mark to be removed, checking the call history and correcting the square may help. Controls differ between games, so the visible card is worth checking against the announced calls rather than treating every mark as confirmation of a match.
Auto daub: marks without a click
With auto daub enabled, the game checks each called number against the active card. If that number appears on the card, the matching square is marked without a separate click. On a screen with several active cards, a single call can mark a match on more than one card.
The mark may appear as a colored spot, a shaded square, or another visual effect. Some games show it as soon as the call appears; others finish a call animation first. A brief delay in the display does not mean a different number was called.
Auto daub changes how a match is marked, not which numbers are on the card. It does not pick cards, change the call order, or fill a square whose number has not been called. If a call has no match on an active card, that card stays as it was.
The call history, when available, can help distinguish a missed-looking mark from a number that was never called. It is also worth checking a game’s settings before play: the name of the option and whether it applies to every active card can vary.
What changes on the card?
The difference is not which numbers appear on the card, but how a called match becomes a visible mark. Both modes use the same card numbers, announced calls, and required winning pattern. Switching to auto daub does not turn a near miss into a winning card.
| Manual daub | Auto daub | |
|---|---|---|
| Who places marks? | The player clicks matching squares. | The game marks matching squares. |
| What does the player watch? | Calls and each active card, to find and mark matches. | Calls and the card’s progress toward the pattern. |
| What if a manual click is missed? | A called match may remain visibly unmarked until corrected, if the game allows it. | No click is needed for that match. |
The flashboard and the player’s card are useful to distinguish here. The flashboard shows calls made in the game; a daub shows which of those calls has been marked on a particular card. A number can therefore have been called even when its square still looks untouched in manual mode.
For example, if a card needs a horizontal line and the last number in that row is called, auto daub normally fills the matching square. In manual mode, the player still has to mark it. Whether a late click can be corrected, and how a win is recognized or claimed, depends on the game’s rules and interface—not on a different winning pattern.
When several cards are in play
With one card open, a player can often check a call at a glance. Add several cards, and the same number may require a scan across different rows and positions. Finding a match on one card does not mean the check is finished: the number might appear on another card too.
In manual mode, each visible card adds another place to look after every call. If the next number arrives while a player is still checking the last one, it becomes easier to lose track of which cards have been marked. A crowded screen can add to that difficulty, especially when the cards are small.
Auto daub removes the repeated marking work. After a call, it marks matching squares across the cards active in that game, without requiring a separate click for each match. The player can still watch the calls and look for a developing line, four corners, or whatever pattern the game requires.
That is the practical difference as more cards are added: manual play asks the player to keep every card current, while auto daub takes care of the marks. Neither mode changes which numbers are called or which pattern counts as a win.
From marked card to recognized win
A daub is only the first step toward a win. Three events are easy to confuse:
- A square is marked when a called number appears on an active card and receives a daub, either automatically or through a click.
- A pattern is completed when the qualifying squares form the shape or arrangement required for that game, such as a line or four corners.
- A win is recognized when the game accepts that completed pattern under its claim and validation rules.
Consider a card one number away from a line. When that number is called, auto daub may fill the final square without any action from the player. In manual play, the player may need to mark it. Either way, the visible line does not by itself explain whether the game will announce a win, ask for a claim, or check the card first.
This distinction matters most when checking cards during play. A manual card can appear short of a pattern because a matching call was missed; an automatically marked card can show a complete pattern while win recognition is still pending. Some games detect qualifying patterns and display the result, while others require a button press or another response within a stated window. The displayed rules determine what counts as a valid claim, including whether timing or marking requirements apply.
The game’s pattern display shows what must be completed. Its claim instructions explain what happens next: automatic detection, a claim prompt, or a validation step. Those details matter regardless of how the squares were marked.
A quick check before the next round
Before play starts, the auto-daub setting is worth checking; its name and location can vary by game. During a call, watch for a number that appears on an active card. If its square marks itself, auto daub is working. If the square stays unmarked until selected, the card is being daubed manually. Checking a matching number matters: a call that is absent from the card reveals nothing about the setting.
Marking is only part of the process. The game’s claim or validation instructions should be checked separately, since a completed pattern on the screen may not be enough to register a win.
