Reading this maze

Alternating gallery starts at row 6, column 3. 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 1, column 5 toggles the gate marked A. Diamond B at row 1, column 2 toggles the gate marked B. Start left and stop at row 6, column 1. A and B keep independent states; a diamond only changes its matching letter. The first slide covers 3 of 29 target tiles.

The verified opening crosses 2 tiles before stopping. A breadth-first search proves a 23-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 Alternating gallery: 29 paintable tiles, ball at row 6, column 3

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.
