Level 3404 Solution

About Level 3404

Passenger routing gets trickier at Level 3404, an extremely challenging puzzle near the end of the current level catalog and among the toughest puzzles available. Each vehicle has limited capacity, so the order you fill them in matters.

Tip

Map out the entire move order on paper or in your head before touching the screen — improvisation rarely works at this difficulty.

Layouts vary, but the solver does not guess — it analyzes your screenshot pixel by pixel to find the walkthrough that fits your board.

How to use this walkthrough

If you are replaying Level 3404, 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.
