Great interactive content for my blog

I wanted to add some fun quizzes and top 10 lists to my blog.
Riddle.com got some great content that is easy to integrate using their plugin and a shortcode you grab on their site.

I wish I could select content to add directly from the plugin, though.
Otherwise, works as advertised and gets good engagement on my site. About 15% of my users engage with the quiz I put into a sidebar. Not bad.

Note: content is only available in English which is another drawback for now.
