It seems that I am in a strange mood today, posting lots of stuff about ugly mobile games. There is a GPS-based poker game:

GeoPoker is a GPS game in which players try to assemble the best poker hand by being the first to find a moving container holding a GeoPoker log. Each time the container is found, the finder is awarded one virtual playing card at random. Each finder chooses the next hiding spot for the container and the GeoPoker log.
