Otto & Bruno

The thick cards in this game show the characters Otto and Bruno, each on an opposing side. Each side also has a number in one of four colors, different from the opposing side. Players gather cards in racks, aiming to collect sets of either four numbers in a single color or four colors in a single number, but periodically the racks and decks are flipped so the alternative card sides are in play.

Listed among the notable card games in Fairplay's 1993 À la carte prize.
