101 Dalmatians - Escape from De Vil Manor cheats and cheat codes for PC

Rooftop Over Kitchen 
Go to young Cruella's bedroom then click on the bedroom to go the rooftop.
To plug the hole in the roof, click on the flowerpot. Now you can click on 
the Trellis on the other side of the roof. Once you have done that, you 
are on your way to the attic. 

Attic 
There is a way out of the Manor in this room. You must go up the pull-down 
stairs in the ceiling. To reach the stairs, the trunk must be moved below 
them. To move the trunk, it must be emptied. The trunk opens with the 
combination to the lock. The combination is on the right-hand wall in 
Nanny's room that is revealed behind a flap of wallpaper from a breeze 
when the window is opened. You can open the window when you jump from 
the bed to the windowsill. Click on the trunk and the combination will 
automatically be entered. 

Game Room 
The game room offers another way out of the Manor. When you make too 
much noise (i.e., barking) downstairs near Horace and Jasper, you will 
get thrown into the game room. If you get thrown in the game room a 4th 
time, the door slams behind you and knocks the pool rack loose. Get the balls 
back into the rack and move the rack by the door. Bark to summon Horace, 
who will open the door and step on the balls! He will run into the wall 
with his backside facing you. The Rhino head falls on Whizzer's head; 
when you click on what's left of Horace, Whizzer will ram him and you 
will be outside!
