How to use this walkthrough

If you are replaying Level 504, use the walkthrough to identify the priority passenger group rather than memorizing every tap. Crowd Express layouts can shift, but the same principle usually applies: clear the group that blocks the most traffic first.

If you are not sure whether this is the right reference, compare the first vehicle and the most crowded lane. A mismatch there usually means you should use the solver instead of continuing with this walkthrough.
