Fill a new match-three board without lines that clear by themselves

A fresh board that already contains three in a row pops before the player has done anything, and filling it again until it behaves is slow and unpredictable. This entry shows a way to fill it once, cell by cell, that never creates a line, and the case where it cannot work.

Why this works

A new piece can only finish a run with pieces that already exist, and filling in reading order means those are only to the left and above. So forbidding those few colours before each choice is enough, with no repair afterwards.

When not to use it

This keeps the board free of lines, not interesting. If you want a start with a ready move, or a layout made by hand for a level, fill it as you like and only check it afterwards for stray runs and for a first move.
