When replacing a joker from the board the rules state I must replace the joker gained from the board with 2 tiles from my hand.
A joker that has been replaced must be used in the player's same turn with 2 or more tiles from his rack to make a new set
My opponent interprets this meaning that I can only use the tiles from your hand. For example J,4,5 or J,6,6. Though I agree that I must use at least 2 tiles from my hand I find nothing that prohibits me from using another tile from the board along with the joker and the 2 tiles from my hand. For example I replaced a Joker from board, a 9+12 from my hand, and an 11 from another run to create the following. 9,J,11,12. My opponent thinks this is an illegal move.
Is this move legal ?
