Hello,
we’ve created a new website on top of Yii2 framework. The website contains brain teasers of all kinds (logic puzzles, riddles, number puzzles, etc.). You can create your own brain teasers in built-in editor.
There is login with Facebook / Twitter implemented (with user management), editor was created using Fabric JS library.
Yii2 is the best! Wish you good luck with your projects.
Regards,
