In PatagoMar, players collect sets of fish in order to advance around a victory point track. In your turn, you can ask another player for a certain type of fish in their hand (which you must also have at least one card of). If the asked player has this kind of fish, they have to give you all cards of that kind. Keep asking players until they say no; then draw a card from the pile - if it matches your request, you can still continue asking. At the end of your round, you can decide to discard sets of the same fish to receive the points printed on the respective cards. Move your pawn forward accordingly - the first player to complete a lap, wins the game.
