Katrielle and the Millionaires' Conspiracy walkthrough
Puzzle Location: The Saveloy (The poster in the right side of the entrance)
A princess has been snatched away to the evil king's castle.
A knight has stepped up to rescue her.
Unfortunately, the knight's beloved horse is a little skittish, so getting to the castle won't be easy.
The horse moves like a knight in chess (in the shape of an L).
You can jump over anything that is in the way, but you cannot land in squares with trees or poisonous lakes.
Touch and slide to move the horse, and work out a path to the evil king's castle.
If you get stuck, you might be able to figure out a route by starting at the castle and working backwards.
There is only one possible space that you can land on in the final step before reaching the castle, so aim for that as you plan your route.
There is more than one possible route.
Starting your journey by travelling to the right wouldn't be a bad idea.
You can't just head straight for the castle.
First you need to head away from it and pass through the square next to the starting point.
Then you can set your sights on the castle.
The answer is as follows.
