From the beginning Dungeoneer has endured accusations of less than perfect rules, though we have tried to rewrite and polish the rules a half-dozen times it was never enough to satisfy the critics (though sales remained strong). However, two fan-made gameplay aids have stood out as the best resources to help you play Dungeoneer.

I have linked to these files for a long time, but I realize they are so valuable that they are worth bumping into the prime position on this blog. I have linked them on the top two links to the right in order to give them maximum exposure, especially for anyone new to Dungeoneer.
