1. Trace the goal, not the whole board
Find the gold arrowhead and mentally extend its exit direction. Look for paths that obstruct its movement. A clear arrow elsewhere may be removable without helping the objective.
2. Follow the chain of blockers
If path A blocks the gold arrow and path B blocks A, inspect B next. Continue until you reach a path with a clear exit. Remove it, then retrace the chain toward the gold arrow.
3. Check a second viewpoint
Two paths can overlap on screen without touching in 3D. The opposite is also possible: a front view can conceal an obstruction. Rotate to a side or top view before committing to a doubtful move.
4. Check both ends of a two-headed arrow
Later puzzles introduce paths that can leave from either end. One exit may be obstructed while the other is clear. An alternate direction can change which blockers need to be removed.
5. Prefer useful moves over all possible moves
From Level 03 onward, campaign boards offer multiple necessary-clearance solutions. Compare the routes that actually help release the gold arrow. Removing every available arrow may add work without advancing the goal.
6. Use retries to test an idea
After a collision, identify the exact obstruction before trying again. In daily mode, your first successful ranked clear is locked; later practice can improve your personal best, but not that published first-clear result.
