Reading this maze

Lettered lanes starts at row 6, column 5. Of the 42 grid positions, 29 are paintable and 13 are walls. The start is already painted; the other 28 tiles remain to be reached.

Diamond A at row 2, column 7 toggles the gate marked A. Diamond B at row 5, column 1 toggles the gate marked B. Start up and stop at row 5, column 5. A and B keep independent states; a diamond only changes its matching letter. The first slide covers 2 of 29 target tiles.

The verified opening crosses 1 tiles before stopping. A breadth-first search proves a 22-slide finish from this exact starting board; that is a reference target, not a move limit. You may revisit any painted tile.

Opening board for Lettered lanes: 29 paintable tiles, ball at row 6, column 5

Diamonds A and B control separate gate groups. Each letter toggles only its matching barred gate; the other group keeps its current state. Changes take effect during the same slide. Undo restores both groups, and Hint searches from both gate states and the painted floor.
