Bus Traffic Fever Level 172 Guide: The Lock Order
Level 172 looks routine at a glance, but the lock order is the entire test. Read the queue, route the matching bus first, and the level opens without a restart. Rush the opening and the wrong color jams every slot behind it.
The Lock Order in Level 172
A late-game lot built around the lock order: the buses clear in exactly one order, and any shortcut that looks faster is a trap. Several buses and passenger groups sit close together, so the trick is picking the one bus that unblocks the rest rather than clearing whatever looks nearest.
Step-by-Step Walkthrough
First Moves: Read the Queue
- Identify the exact first bus in the sequence.
- Dispatch it even if another bus looks closer.
- Confirm the slot empties before you move on.
Midgame: Follow the Queue
- Re-read the queue after the first bus boards.
- Confirm which color is now at the front.
- Line up the next matching bus while the slot empties.
Finishing: Clear the Level
- Send the remaining matching buses one at a time.
- Confirm every passenger group has boarded.
- Replay the opening once so the order sticks.
Verified Video Walkthrough
Focus on the lock order. The correct first bus is the one the front color asks for, not the one that looks closest.
Grabbing the nearest bus instead of the one that matches the front of the queue. The wrong color jams the slots and forces a restart.
Pros and Cons
Pros. The lock order is clearly signposted, so once you read it the level opens up cleanly and is easy to replay.
Cons. The lock order punishes a rushed first move, so a single wrong dispatch can look identical to a near-success.
