From the publisher's blurb:
Have you ever wanted to roleplay in a fantastical world, deep in space, or maybe the untamed wild west? Heads or Tales allows you and your friends to roleplay in any setting you’d like; the only limit is your imagination! The rules are simple: tell a story with a group of friends, and leave your fate to the flip of a coin.
Heads or Tales is for groups with any level of experience with roleplaying games. Since all you need is a coin, you can take the story with you on the go. Grab a coin and some friends, and start telling your story today!
