A straightforward game. The riddle master gives a riddle, the first person to call out the answer becomes the riddle master. The riddle master has one day to think of a new riddle. If no one solves the riddle within three days the riddle master must give a new hint, although the riddle master can give a hint whenever he/she wants to. At anytime, the riddle master can pass up their turn leaving it up for grabs, and they can use it again later. If a riddle is too vague people can ask for a hint, but no guarantees till every third day.

I'll start.

They tail their masters in the sun
Yet they wander freely in moonlight
Though sadly, they must hide from their opposite
Or they will be swept away by light
