How sharp are your eyes? The following pages each contain six similar pictures. See if you can spot the image that’s different from the others, or in some cases, the two pictures that are the same.
The mind-strengthening puzzles become more difficult as you progress, so if you need help or just want to check your guesses, go to the end and peek at the answer key.
Feel free to print as many copies as you want, just not for commercial gain.
