Clear the Blocker First

Level: Intermediate

Remove whatever is blocking the arrow you want to clear.

If the arrow you want to clear is blocked, you need to first remove the arrow (the blocker) sitting on its path. If that blocker is itself blocked, trace back to whatever is blocking it.

Starting from your target arrow and tracing the chain of blockers backward naturally reveals the order you need to clear them in. This is the key mindset for solving tangled boards.
