Jam Bus:Sandfall

The twist here is that the sand sits in layers. Each bus has a color and a route, and it can only collect sand of its own color. Lower layers must be cleared before the colors above them become reachable.

That turns each board into a sequencing problem. A bus that looks free may block another one, and a visible color may be locked behind sand underneath.

You tap a bus and it follows its arrow-marked route. Crossing paths are the main risk, since two buses that meet cause a crash. Controls stop at the tap, so the effort goes into planning the order.

Levels get harder with trickier routes and more layers. The store text frames it as a way to fill quick breaks, and the five screenshots show a clean, colorful look.

Most titles in the bus category lean on driving or crowd management. Bus Arrival, Bus Fever Party!, Bus Traffic Fever! and Bus Crowd are listed as alternatives, and Baby Panda's School Bus targets a younger audience. Jam Bus:Sandfall is closer to a color-matching puzzle than a simulator.

If you want steering and passengers, look at those instead. If you want a calm tap puzzle, this one fits.
