Plan the fuel. Drive it cheap.
Each station shows its price per litre. Tap + and − to choose how many litres to buy there. The car burns 1 litre per 10 km; each stretch of road shows what it costs (−3 L). The tank holds only so much. Arrive with shows the fuel left at each stop.
Undo takes back a stepper change (3 per trip). Hint sets one station to the cheapest plan. Stars: the cheapest bill earns three.
