Trio is a memory game – turned inside out a bit. To start with, the challenge is not to find matching pairs but matching triples, the „trios”. This is harder than you think especially because the players (2-4) may turn only 2 cards at a time and colors make a difference too. The period transport vehicles, as well as the steampunk style, are only a kind of „skin” of the game; the design can be adjusted to any other image as required.
