A Thieving Opportunity was one of five Flash games featured on the original Sly Cooper and the Thievius Raccoonus website. It is a "spot the difference" game in which the player must find all of the differences between two scenes.
The game takes place in the Panda King's lair. Upon starting the game, the player can view the original scene and then click a button to view the altered scene. In this new scene, the player must click on the spots that are different. There are eight in all, and each one that is found will be circled in blue. The scene can be toggled between the original and altered version as many times as needed.
