Laying off, or isleme, means adding tiles to melds already on the table after you have opened.

Once you have made your 101-point opening, you can extend runs and sets that are on the table by playing matching tiles from your rack. This helps you shed tiles quickly and move toward finishing. You cannot lay off before you have opened, so reaching the 101 threshold first is essential. Skilled players plan which tiles they will lay off to empty their rack as fast as possible.
