You are the head of the Gaztrans corporation that supplies natural gas to the private sector. Instability in a region wrecked havoc in the distribution system and caused many houses to be disconnected from the main pump. Now your task is to restore the pipes network so every house is connected back to the pump.


If you have ever played the "Netwalk" game you may use similar techniques to solve the puzzle.

You will receive an email with the serial number after the payment.
