# EXTENSION JAM! ## Make extensions and put them here šŸ™‚ ## There is no theme! Do anything you want! Anyone is welcome to join _Poll ([view on site](https://forum.makecode.com/t/extension-game-jam/43367/1))_ The extensions will be judged by me and up to 3 others By extensions I mean stuff that adds new blocks into the game (Or new stuff into javascript) [https://github.com/sargedev/betterarrays](https://github.com/sargedev/betterarrays) for example If you donā€™t know how to use github, just share your makecode project link here If you do, then oviously just share the github link here You can make an extension and judge, but you may not vote for your own extension as the best if you do so _Poll ([view on site](https://forum.makecode.com/t/extension-game-jam/43367/1))_ Same as above, up to 3 judges First users to vote to be a judge will be a judge (Then the next users who voted, if one of the judges hasnā€™t voted for an extension) If you get the most votes on your extension, you win (donā€™t expect a prize from me tho) good luck! Rules and specifications: You can submit an extension you have made already if you want The extension jam is over when the judges decide (probably around 1-2 months) You can submit an extension that is not that good, every extension is welcome Usefulness and creativity are the main judging factors and other stuff like the UI and yeah other stuff You can also remix other peoples extensions (with permission) You can have up to 3 submissions (1 is reccomended tho) Other titles that maybe will happen: Honorable mention Most creative idea Most unique ---
