OBJECTIVE
Every coloured dot has one twin of the same colour. Join each pair with a pipe so the pipes cover every single square on the board without crossing.
HOW TO PLAY
- Press a dot and drag to its matching dot to lay a pipe between them, then release.
- Pipes cannot cross or overlap. Drawing back over a pipe, or across another colour, erases from that point so you can re-route freely.
- You win only when every pair is joined AND no square is left empty, so plan routes that fill the whole grid.
