Reading this maze

Three-gate return starts at row 2, column 2. 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 2 toggles both barred cells marked A. Diamond B at row 3, column 6 toggles the gate marked B. Start up and stop at row 1, column 2. Both A gates share one state, while B stays independent; plan the closed bars as stopping points. The first slide covers 2 of 29 target tiles.

The verified opening crosses 1 tiles before stopping. A breadth-first search proves a 27-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 Three-gate return: 29 paintable tiles, ball at row 2, column 2

A and B keep separate states. The A diamond toggles both A gates together, while the B diamond toggles only B. Every barred cell must be painted. Undo restores all gate states, and Hint searches your current trail.
