What gods were there in ancient religions related to games? I know there were gods related to chance, but even in the ancient world, not all games relied on luck (Olympic games, other sports competitions, Go, Chaturanga).
I'm searching for gods, but will welcome other mythical creatures as well, for the sake of this question most prominent immortals/wise kings/saints etc. can be swapped for gods. The relation between them and games has to be direct, no "well they were about strategy, so they are also gods of strategy games" etc.
Unfortunately, when searching for gods related to games on google, your results are flooded with modern game titles with "god" in the title, and I can't seem to find a related page on Wikipedia.
