Fix a match-three board that miscounts runs of five and L-shaped matches

Lines of five clear only three tiles, an L-shape clears one arm, or a tile counted twice pays double points. Nearly always the cause is checking too early or clearing while still looking. This entry shows how to make the AI find every matched tile exactly once.

Why this works

Looking and changing must not happen at the same time. If you clear tiles while you are still searching, you destroy what the next search needs to see. Find everything first, keep each tile once in a single collection, and only then change the board.

When not to use it

Finding everything first is not enough where the rules want a prize for the shape itself, such as a special piece for a line of four or a bomb for a T. Then you also need to know which run formed which shape, not only the set of tiles.
