Bots ‘n Pieces is a narrative role-playing game (RPG) about playing a team of light-hearted, ragtag, clapped-out robots on a contrastingly dangerous and deadly junk-strewn planet, the frontier world of Tartarus. The game works best with 3 to 4 players each with a robot Player Character (often called a PC or Bot), plus a gamemaster (GM).

​

The game uses Action Pools (dice pools) for players to defeat Challenges. Players build Action Pools by spending from a limited set of themed Programs to create a narrative description of their actions. Each Program is represented by a dice type: d4, d6, d8, d10, or d12. Players can also build Action Pools together by Combining the robotic bodies of two or more Bots, creating a new Character for a brief time.
