For the given entrances, find all associated exits.

You are given a pipe maze where one entrance is marked by a red square.
You have to find all exits you can get to from the given entrance and mark them with blue squares.

If you found all exits, a further entrance will be marked red, and again you have to find all exits.
Similarly, there will be also a third challenge before you get the win message.

Solutions are included.

All mazes presented here have been created with the help of other Zillions games such as the games 'Escher 4', 'Escher 9', 'Escher 10' (select the random variant there) and 'Celtic Designs' by the same author.
