ROLLOR SWAP FAQ’s

Q: What is the R.O.L.L.O.R. Swap?

A: Before play begins, it is the process of swapping up to 21 tiles to improve a mahjong hand.

It is often referred to as the Charleston in American Mahjong.

The swapping of tiles is done three tiles at a time in “ROLLOR” order, broken up into two rounds.

Round 1 (R.O.L.) is mandatory. Any player can end the Swap after the Round 1.

If the Round 2 (L.O.R.) begins, it must be completed. The swap ends with the courtesy pass.

Q: When can I do a Blind Pass in the R.O.L.L.O.R. Swap?

A: After the First Left in Round 1, and after the Second or Final Right in Round 2, players have the option to pass one, two, or three tiles blindly. This means they will pass a portion of the tiles passed to them, tiles remaining facedown and unseen.

Players must always pass 3 tiles during each turn of the Swap. If a player selects less than 3 tiles to pass during the first L pass or final R pass, the player can supplement the remaining number of 0-3 tiles needed by ‘blindly’ choosing and passing on immediately.

Q: When can a player stop the R.O.L.L.O.R. Swap?

A: Any player may stop the swap after the mandatory first round and before the optional second round begins. Once stopped, players do not proceed with round two but do have the option to courtesy pass.

Q: What is the Courtesy Pass? 

A: The Courtesy Pass takes place after the R.O.L.L.O.R. Swap. Players determine how many of the 3 unwanted tiles to courtesy pass with the player sitting opposite at the table. If less than 3 tiles are passed, the lowest number of tiles willing to be passed determines how many tiles will be passed to the person across.
