Three matches are sitting on a table. Without adding another make the three matches four. You are not allowed to break any of the matches.
Common Wrong Answers
“Add a fourth match”
The riddle explicitly states that you cannot add another match.
“Lay the matches flat”
Laying the matches flat does not change their count or form them into the number four.
“Stack the matches”
Stacking the matches does not create a visual representation of the number four.
