• Collaboration is the key

"Completely Empty" - is the first mission from out top player veky. The mission was released last week and already went through a random review process.

"Cut Sentence" - is a mission that was released last week and it is not in random review mode, so you can go and check it’s leaderboard if you have solved the mission.

"What can you do with solutions" - is one of our previous blog-posts where we have listed all the features we have around solutions, but then it becomes a discussion around what should be changed or improved in CheckiO’s sharing solutions schema.

StefanPochmann - is a user who replace Moff in TOP3 Monthly LeaderBoard. I want to remind you, that this month is all about short new missions.
