Do Anything D6 (let’s call it DAD6 for short) is a generic, standardized system of running challenges in any tabletop roleplaying game. It is based on the x-in-6 system from classic fantasy roleplaying games of the ‘70s and ‘80s. It is designed to be plug-and-play: drop it into your system of choice whenever you need or want to. It is self-contained and relies purely on six-sided dice.
