Move three matches to new positions in the diagram so that there are four squares and no loose ends.

Double click a matchstick to rotate it through 90o or, to rotate the last stick moved:

This type of puzzle has been around for many years. There were particularly popular around one hundred years ago when matches were widely available as many people smoked.

"The definitive modern match was born in mid-19th century by Swedish chemist Gustaf Erik Pasch. His ‘safety match’ design moved the phosphorus away from the match itself and onto safe striking surface, enabling creation of much safer, easier to use, and cheaper matches. His invention was greatly popularized by Swedish industrialist and inventor John Edvard Lundström who started first mass production of this type of matches." (Source: historyofmatches.com)

Today matches are not such common items but the puzzles remain. You can work on them using lolly sticks, toothpicks, headless matchsticks (available from craft shops), pencils, crayons, cotton buds and on a computer as you are doing now.

"In fairness the instructions should reveal that a matchstick does not have to be a part of a square but can extend as long as it isn't moved."
