How to play:
• Each number appears twice on the grid
• Draw a path connecting each pair of identical numbers
• Paths are made of orthogonally adjacent cells (up/down/left/right)
• Every cell must be covered by exactly one path
• Paths can touch each other diagonally, but cannot share cells
Controls: Tap a number to start its path, drag through cells to extend. Tap the same number again to finish.
