Tips & Tricks

• Start from the source and work outward — connect what you can see first.
• Corner pipes only connect in 2 directions — use that to narrow possibilities.
• Cross pieces connect all 4 directions — they can go anywhere on the path.
• Use hints when stuck — they highlight the next pipe to rotate.
• Watch the par score — fewer moves means more stars and bonus hints.
