Yucata.de is an online game system. Games are played in a web browser, one turn at a time, which could take days or weeks, depending on the game and how often the players take their turns. But you can see who is online and using the chat system may ask for a 'quick game' to be played.
Yucata offers a rank system where you start as a New villager and may climb up to be an Itzamna, a Mayan upper god and creator deity thought to be residing in the sky.
Games may be replayed after they are finished to study strategies.
