Parking is the main constraint in Jam Bus:Sandfall. A bus reaches the road quickly, but it may stay there until enough matching sand is available. Several unfinished colors can therefore fill the entire row.
Do Not Queue Every Visible Color
A visible bus is not automatically useful. If its matching sand is covered by another layer, the bus will wait. Release colors that can collect now or that the verified solution uses to open a required route.
Repeated Colors Need Separate Phases
Boards such as the rose bouquet and pizza contain repeated red or yellow regions. Do not send every bus of that color during the first region. Some vehicles belong to later layers.
Parking Upgrades Are Still Limited
Some levels increase the number of parking positions. Keep at least one of the new spaces open. Filling every upgraded position creates the same lock at a later point.
Compare Board States
Pause the walkthrough after a major sand layer clears. Compare both the remaining picture and the buses still in the field. Matching only one of those states is not enough.
