Most of us have handled a standard deck of playing cards at one time or another. The basic card designs with which we are all familiar have remained unchanged for hundreds of years. Do you think you could spot an error?

This special deck cards has a twist. Each card is wrong in one, or more ways. Some errors are glaring, and others are more subtle. A challenging exercise in perception. Take a test yourself, and see if you can spot the errors.

The What’s Wrong? deck of cards is available at the Illusion Gift Shop.
