Jam Bus:Sandfall combines a vehicle-routing puzzle with color matching. The upper panel contains layered colored sand. The lower panel contains buses that point in different directions. A bus must have a clear route to the road before it can leave the field.
Check Three Things Before Every Tap
First, trace the bus direction to the edge of the vehicle field. Second, confirm that sand of the same color is currently exposed. Third, check the parking row. A bus that cannot collect sand may remain parked and use space needed by the next color.
Why Route Order Matters
Short buses often block long buses. Moving the nearest vehicle is not always correct. Prefer a move that both collects exposed sand and opens a route for another vehicle.
Use Parking as a Limit
Keep one position open when possible. That reserve space lets a newly exposed color enter without forcing a restart. An unlocked parking upgrade increases capacity, but it does not remove the need to manage the queue.
When to Restart
Restart when the parking row is full and none of the parked colors matches the exposed sand. Continuing from that state usually cannot restore the verified route order.
