ArrowsRotate before you move
Drag the board to look around it. On a touch screen, use one finger to rotate and two fingers to zoom or move the view. Inspect the depth of a path as well as its visible outline.
Follow the arrowhead
Select an arrow to slide it in the direction it points. Its entire path needs room to leave. Some later arrows have two heads and can be removed from either end; check both directions.
Protect your three hearts
An arrow colliding with another arrow costs one heart. The third collision ends that attempt. Retry starts the same board with the timer, moves and all three hearts reset.
Finish by freeing the gold arrow
Every board has exactly one single-headed gold objective. Move that arrow out to complete the puzzle and advance automatically in the campaign. Extra removals are optional if the objective is already clear.
