Den-Den is a popular game in the RPG setting Tékumel, but the rules descriptions are sparse.
I've developed a version by combining the details mentioned in the texts with hexagonal chess and the ancient Indian game of chaturaji.

The rules document is here, if you want to look it over and come with suggested changes:
