Longer than the tutorial, and with possible wrong guesses. It felt much more like a "real go". For the tutorial you get 10 minutes, this one gives you 60. In reality it's 30 though as the time gets cut in half a few minutes in.
Still, I enjoyed it despite my mixed review. Don't think I'll buy unless I spy it cheap, simply because it's a single-play game. Good one for board-game cafes or to borrow though!
Just spotted that it's by same publisher as TIME Stories
