Sand Truck

Sand Truck is a clever logic puzzle where you run a sand factory and route coloured sand to the right trucks. Each truck can only be loaded with sand that matches its colour, so you must guide the sand through the factory’s network of pipes — adjusting the pins and paths — to make sure every colour reaches the correct vehicle. It’s a satisfying brain-teaser built on planning and cause-and-effect rather than reflexes: study how the pipes connect, work out the sequence, and set your pins so nothing ends up in the wrong truck. Take your time to trace each path before committing, and the trickier levels click into place. With steadily more tangled layouts and a real ‘aha’ payoff, there’s a good pull to solve just one more. Smart, calming and moreish, it’s a great pick for logic-puzzle lovers.
