Reading the Board
Before making any moves, scan all buses and identify which animals need to go where. Count the animals of each type to make sure you have enough bus space.
Move Order Matters
Start by freeing animals that block the most options. If a cat is sitting in the panda bus and blocking a dog from moving, move the cat first.
Using the Hint System
Each level gives you a limited number of hints. Use them only after you have tried solving manually for at least thirty seconds. Save remaining hints for later, harder levels.
