In Thief King, you play as a thief who has to rob various locations in order to get to the next level. On your way, you have to take care of security guards. If you get caught by a guard, you will have to start over. Luckily, you can utilize stealth to sneak past security cameras, lock doors, and even security guards.

With Thief King, you can also find a lot of different locations to rob, such as a supermarket, a jewelry store, a casino, a warehouse, and many more. Once you have gotten away from security, you can go ahead and loot the location.
