Because of your forbidden love for the king's daughter, you have been sentenced to the usual punishment: death by tiger.

As the king is a fair man, you have a fighting chance to escape your doom. You are put in a room with four doors. Behind two of the doors are tigers. Behind the third is a dragon. Behind the fourth is the princess; if you manage to open her door, the king will bless your wedding.

On each door is a number and a plaque. You have been assured that the door leading to the princess has a plaque that tells the truth, and that the doors leading to a tiger have plaques that lie. You are not told whether the plaque on the door leading to the dragon is a lie or the truth.

Can you escape death and find the princess?
