Regex Crossword is a puzzle game in which the clues are regular expressions: fill in the grid so every row and column matches its pattern. A tutorial teaches the basics, then puzzle packs increase in difficulty, and players can make and share their own puzzles. It is a great way to get comfortable with regex.
