The eighth annual js13kGames competition results are in, and we can’t wait to share the winners with you. If you’re not familiar, js13kGames is a community-run game jam which challenges developers to create a JavaScript game in 13kB or less in 31 days.

This year’s theme is “back” and over 200 games were submitted. Here are the top ten games based on the final votes from the community themselves, specifically the developers that submitted the games. It’s amazing how much fun you’re able to create despite the constraints on size, time, technology, and theme.

Top ten winners

1st – Xx142-b2.exe

“This was an incredible entry! The multiple overlapping timeline puzzles were just great. This was an excellent use of the theme, and near perfect execution all around.” -Christer Kaitila

Fun fact: @mvasilkov is no strangers to game jams. They created a great Git Invaders game for Game Off in 2012.

That’s just the top ten—there are plenty more to explore. Check out space invaders in VR, a pointy platformer, and a game that’s so brilliant, it will make you flip. We also found the missing green square from your contribution graph.

Pro-tip: If you thought playing the games were fun, try cloning or forking them, and tweaking some variables. Give yourself infinite lives, have fun with gravity, add even add some humorous sound effects—the possibilities are up to your imagination.

Kudos

Congratulations @end3r on hosting yet another great JS13K competition. It takes a (digital) village to build something like this: special thanks to @tricsi for building the new voting app, @platane for building the validation bot, @straker for the small-but-mighty kontra.js that many people found useful, as well as @michalbe, @stasm, and @cyberdees for their support.

Thanks to everyone who took part in the competition: jammers, sponsors, experts, and those who took the time to play the games. We can’t wait to see what you create with 13 kilobytes next year. <3
