Bus Loop is a parking-jam puzzle with a colour-matching twist. You release buses from a crowded car park, passengers walk around a loop, and each bus can only leave when its arrow path is clear. The goal is to clear every bus and every passenger before the waiting bays jam.

1. The basic turn

  1. Tap a parked bus.
  2. If the path in the direction of its white arrow is clear, the bus drives to a waiting bay.
  3. Passengers of the same colour board when they reach the boarding point.
  4. When the bus is full, it leaves and frees the bay.

If another vehicle blocks the arrow path, the bus bumps forward and returns. Move the blocking vehicle first. You do not need to tap the arrow itself — tapping the bus is enough.

2. Match the bus to the passengers

Each colour on the loop has a matching bus. Small buses carry 16 passengers, medium buses 24, and large buses 40. The remaining count is printed on the bus, and a progress bar fills as passengers board.

Key rule: passengers only board at the boarding point, not anywhere on the loop. Watch the colour that is about to reach the bottom before you release a bus.

3. Waiting bays

Every level starts with four waiting bays. If all four are occupied and no bus is loading or departing, a 6–8 second timer starts. If the timer ends, the level fails. You can free a bay by sending a bus whose colour is currently boarding, or add a bay with coins, an ad, or a booster.

4. Boosters

  • Crane: the first use in each level is free; later uses require a short rewarded ad.
  • +1 bay: watch a rewarded ad to add one temporary bay.
  • Rainbow bus: watch a rewarded ad to remove one parked bus and its matching passengers.

Boosters are assistance, not a requirement. Saving them for a genuine jam is usually better than spending them on the first difficult colour.

5. Progression

Levels 1–60 are open to everyone. From level 61, you must clear the previous level to unlock the next. The game has 200 levels across 20 chapters, and each chapter introduces a different loop shape. Progress, stars, coins and the current level are saved in your browser.

6. A simple first-level plan

  1. Look at the buses whose arrow paths are already clear.
  2. Release a colour that is close to the boarding point.
  3. Keep at least one bay free while a bus is loading.
  4. Clear one colour completely before opening another.
  5. If you get stuck, pause and read the loop before tapping.
