We've just launched the Nintendo Open Challenge* today. A story of Centaurians sending encrytped data to the Earth. Your mission: be a worthy representative of the Human species by decoding their messages, thus proving that we have not yet fallen into Idiocracy. Pretty tough, needless to say, but still fun and challenging. We hope you'll like it :-)
* CodinGame's Open Challenges are ongoing mini-challenges, held over several days, that can be solved just for fun or to get in touch with tech companies you like, when you like.
