Matchstick Puzzles

Matchstick Puzzles is exactly the logic puzzle you remember from puzzle books: a shape or equation made of sticks, and a challenge to move a specific number of them to make a new, correct shape. There's no timer pushing you and no penalty for staring at the same arrangement for a while, which is really how these puzzles are meant to be solved. Move a stick, see if it still forms a valid figure, and if not, try a different one.
