It takes confidence to soft-pedal the actual tutorial content. Too
many mainstream game studios build their opening tutorials to
leave no possibility of misunderstanding — they browbeat you out
of fear that you won’t get it. Vollmer and Wohlwend instead
designed the beginning of Threes in a way that encourages organic
understanding. The game assumes that there’s a reasonably
intelligent and playful person on the other end of the line.
