'''Matchstick puzzles''' are rearrangement puzzles in which a number of [[matchstick]]s are arranged into shapes or numbers, and the problem to solve is usually formulated as moving a fixed number of matchsticks to achieve some specific other arrangement.

The puzzles may ask the solver to alter some mathematical equation,<ref>{{cite book |last1=Publishing |first1=Arcturus |title=The Pub Quiz & Puzzle Book |date=15 September 2011 |publisher=Arcturus Publishing |isbn=978-1-84858-413-6 |page=155 |url=https://books.google.com/books?id=NRsEAwAAQBAJ |language=en}}</ref> often with numbers represented as [[Roman numeral]]s, or [[Arabic numerals]] in a [[seven-segment display]] typeface. Other puzzles challenge the solver to rearrange a crude matchstick picture.<ref>{{cite book |last1=Grabarchuk |first1=Peter |title=Modern Classic Puzzles |date=2008 |publisher=Sterling Publishing Company, Inc. |isbn=978-1-4027-4808-0 |page=6 |url=https://books.google.com/books?id=-pPVoODe4QkC |language=en}}</ref>

Some matchstick puzzles require [[lateral thinking]], such as changing a number into a mathematical symbol.<ref>{{cite news |last1=Bellos |first1=Alex |title=Did you solve it?

Puzzles may also be set with no starting position, simply challenging the solver to create an arrangement using a number of matches. One example that requires lateral thinking is to form four [[equilateral triangle]]s from six matches; this can only be done by arranging the matches in a three-dimensional [[Pyramid (geometry)|pyramid]] shape.<ref>{{cite book |last1=Fulves |first1=Karl |title=Big Book of Magic Tricks |date=13 July 2012 |publisher=Courier Corporation |isbn=978-0-486-17077-0 |page=27 |url=https://books.google.com/books?id=l2DCAgAAQBAJ |language=en}}</ref>
