Blind pass

Which passes allow a blind pass, and how many tiles can go blind?

Question 1 of up to 2

Is this the last pass of a round — the first left (third pass of round one) or the last right (third pass of round two)?

Read every possible ruling for this situation

Blind ok

Yes — pass one, two, or all three blind

Standard rule
Yes, you may pass blind here. You still pass three tiles, but one, two, or all three of them may be taken — unseen — from the three being passed to you, with the rest coming from your own hand. Take the unseen tiles from the incoming pass without turning them over, add your own tiles to make three, and pass; only then look at what is left for you. Saying “passing blind” is polite but not required, and more than one player may pass blind on the same pass. If so many players want to pass blind that the tiles get stuck, the League’s rulebook describes an I.O.U. method: the player with the most tiles to pass starts, says how many tiles they owe, and settles up when the pass comes back around.
Why
The last pass of each round lets a player protect a nearly finished hand without being forced to break it up.
Common house rules
Some groups require you to announce a blind pass, and some tournaments penalize peeking. A few tables allow blind passes only in the second round; the standard allows them on both the first left and the last right.

If your table agreed on a house rule before the game, that rule wins.

Not this pass

Not on this pass

Standard rule
Not on this pass. Blind passing is allowed only on the first left — the third pass of the first round — and the last right — the third pass of the second round. On the other four passes (first right, first across, second left, second across) all three tiles must come from your own hand. The courtesy pass has no blind option either; there you simply agree on fewer tiles.
Why
The blind pass exists to close out each round; opening it on every pass would let players sit out the Charleston entirely.
Common house rules
A common mistake is to allow blind passes only at the very end of the second round. If your table has always played that way, agree on which version you are using.

If your table agreed on a house rule before the game, that rule wins.

Looked no blind

Looking breaks the blind pass — a reminder, not a penalty

Standard rule
Looking at the incoming tiles breaks the blind-pass rule — the whole point is that they are passed unseen. The standard rulebook sets no penalty for it; the League’s advice is to remind the player that blind tiles must not be looked at. Finish the pass with three tiles and move on, and treat the look as a lesson rather than a fight.
Why
The rule is about fairness in information, and a reminder fixes future behavior better than a punishment would.
Common house rules
Tournaments often do penalize peeking at a blind pass, sometimes severely. Social tables may agree on a small penalty too.

If your table agreed on a house rule before the game, that rule wins.
