Welcome to Double Down #

Double Down (or DD20) is a rules-light, generic D20 TTRPG system geared toward roleplaying, featuring a core push-your-luck mechanic. The rules are completely free and playing only requires the following additional materials:

• a character sheet per player
• one or more reference sheets to share
• one or more 20-sided dice to share

I designed Double Down in my free time for personal use. If you enjoy the system and have any stories or feedback, please reach out to me at [email protected]. 🤍
