How to Play

• Objective: Connect every pair of matching colored dots with a pipe.
• Draw: Press a dot and drag to its partner. Pipes follow your finger through adjacent cells.
• No crossing: Pipes can't overlap. Drawing over another pipe trims it.
• Fill the board: You win only when all pairs are linked and every cell is covered.
• Undo: Drag back along a pipe to shorten it, or hit Reset.
