BUS LOOPBus Loop contains 200 levels, grouped into 20 chapters. Every chapter changes the shape of the loop as well as the density of the car park, so the later game does not look like the same oval repeated 200 times.
Unlock rules
Levels 1–60 are open to everyone. From level 61, each level unlocks only after the previous one is cleared. If you are returning to the game, your furthest cleared level is preserved in your browser.

What changes inside a chapter
Each chapter uses the same loop silhouette for ten levels, but the car park, colour mix, palette, central island and passenger count change. The early levels of a chapter teach the new geometry; the last two usually combine it with the hardest colour set.
Difficulty without dead ends
Every level is generated around a valid clearing order. The challenge is not finding a hidden trick; it is managing bays, colours and timing. If a level feels impossible, check whether a bay is occupied by a colour that cannot finish, then restart with a different release order.
