I finished one of the tasks. And, I imagine I could finish at least some of the others. But, I wasn't being paid, and it wasn't very entertaining, so I stopped. EDIT: Got all the way through several other tasks that suddenly looked interesting while watching the replays available of the frontier models. If you paid me $250, I'd finish them all, though probably not optimally. I still don't know how I'd do against the private sets. They should ad a "global" and "friends-only" leaderboard (like the Zachtronics games, etc.) and really see the competition (at least human competition) heat up.
