ITO - How to Play in 3 minutes - Arcane Wonders - BoardgameNinja
You can play ITO with up to ten people. Besides completing the task, you also learn a lot about your fellow players who quantify their answers to the central question. Or more accurate; who find an answer to the number they have been given. What is the one thing your neighbour can do all day? Or more interesting; what can your neighbour do about 25% of their time?
ITO is unexpected, psychological, fast playing and a very satisfactory feeling when you pull it through!
