Pooka is not a game. Pooka is a board game assistant to help simplify and streamline some aspects of games.
This is the Pooka core which functions as a command center for Pooka modules.
In addition to helping you keep score, Pooka modules maintain a scoresheet history (or log) of all past games.
From the Pooka app you can browse for Pooka modules available in the marketplace.
You can also browse existing games, launch new games and manage your friends list.
Combined with the Pooka modules such as Pooka Universal, you can keep score in a variety of games such as Settlers of Catan, Agricola, Scrabble, Monopoly, Hearts, Spades and many more.
