The js13kGames competition is an annual JavaScript coding event that encourages web and game developers to create a game in 13 kilobytes or less, based on a theme announced at the start of the month-long challenge. Organized by @end3r since 2012, the competition welcomes participants of all skill levels, offering an opportunity to enhance JavaScript and game development skills while promoting creativity and fun. This year's event begins on August 13, with the theme revealed at 13:00 CEST, and participants can track progress and share their experiences using the hashtag #js13k. Resources and tutorials are available to assist developers in maximizing the limited 13 kilobyte space for their creations. Last year’s theme, "offline," inspired nearly 300 open-source games, showcasing a variety of genres, including shoot ‘em ups, platformers, and space exploration simulations, all playable in browsers.
