Reading this maze

Coral interlock starts at row 2, column 4. Of the 42 grid positions, 30 are paintable and 12 are walls. The start is already painted; the other 29 tiles remain to be reached.

The switch at row 1, column 3 toggles gate A on every entry. Start left; opening the gate changes where later slides can stop. The first slide covers 4 of 30 target tiles; 26 remain.

The verified opening crosses 3 tiles before stopping. A breadth-first search proves a 21-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 Coral interlock: 30 paintable tiles, ball at row 2, column 4

Switch A is a diamond; gate A has bars when closed and a dashed outline when open. Entering the switch toggles it immediately, including during a slide. If you get trapped, undo or restart; Hint checks the current gate and painted-floor state.
