Quick tips

• Look at the whole map first. Spot the clusters of houses before you tap anything.
• Sweep, don't zigzag. The best loops usually go round the map once and rarely cross themselves.
• Nearest isn't always best. Flying to the closest house each time can leave a long trip home at the end.
• Mind the trees. Two houses side by side on the map can be far apart if a row of trees is between them.
• Use the keys. Letters A to H add a house, Backspace undoes and Enter flies.
