Reading this maze

Four diamonds starts at row 2, column 6. Of the 42 grid positions, 31 are paintable and 11 are walls. The start is already painted; the other 30 tiles remain to be reached.

Diamonds A at row 1, column 3 and row 2, column 5 toggle the gate marked A. Diamonds B at row 2, column 3 and row 2, column 7 toggle the gate marked B. Start right and stop at row 2, column 7. Either matching diamond flips its letter; both A diamonds share A, and both B diamonds share B. The first slide covers 2 of 31 target tiles.

The verified opening crosses 1 tiles before stopping. A breadth-first search proves a 26-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 Four diamonds: 31 paintable tiles, ball at row 2, column 6

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.
