Casino-style game with cards and chips. Each hand has three phases (labeled "Hearts", "Poker", and "Michigan Rummy", though only the poker phase has any resemblance to its namesake game). All cards are dealt out, including one extra hand which remains unseen. The first phase pays off for holding certain cards or combinations; the second is a hand of poker, each player selecting five cards from his hand to play; in the third phase, players play out their cards Fan Tan-style, and the first to go out wins chips.
The book Games We Play pictures a version of Poch published in ~1830 in Nuremberg by Verlag Fr Scharrer. From this illustration we can see the evolution of Pope Joan to Poch, which was further refined into the Tripoley we see today.
