Deponia solution: use blasting plan correctly

Deponia is a point-and-click adventure game by Deadalic Entertainment. It is the first part of a four-part series and is set in the eponymous world Deponia. Here the hero Rufus has to solve all sorts of puzzles. One of these puzzles is the blasting plan, which you use to shorten a queue.

How to solve the blasting plan puzzle?

You have to solve the blasting plan puzzle after falling back to Deponia with Goal. Rufus needs to speak to the mayor quite urgently, however there are three people ahead of you in the queue. These go home, however, as soon as you have managed to set off the blast alarm.

1. Talk to the three people first. These give you the important hint that the roofer is now a hatter.
2. Don't forget to take the magnets from the board, which is on the left side in the foyer.
3. Go to the alley with the blasting plan and push it with the magnets.
4. In which houses you trigger the blasting plan, you can tell by the hats of the three people in the queue. The hat corresponds to the respective roof of the house.
5. Attach the magnets - at the top of the fourth and fifth square from the left and at the bottom of the fourth square from the right - and leave the blasting plan again.
6. Now click on the bell to the left of the plan. Die Alarmanlagen der Häuser ertönen und die Wartenden kehren schnell zu ihren Häusern zurück.
7. Wenn Sie jetzt in das Foyer gehen, gibt es keine Warteschlange mehr und auf dem Boden finden Sie eine Nummer, mit der Sie direkt zum Bürgermeister gelangen.
