Polyhedra Games is a publisher specializing in tabletop role-playing games and video games, established by Clipper Arnold in 2019.

About
The name "Polyhedra" alludes to the multifaceted dice integral to tabletop RPGs. The company has successfully completed four Kickstarter campaigns supporting Justice Velocity, Nebula Chaos, The Plagued Crypt of Helvete, and Toku Legends.
Tabletop RPGs
Founded in 2019 concurrently with the Kickstarter launch for Justice Velocity, Polyhedra began its operations in Los Angeles. The game mechanics derive from the unpublished urban fantasy RPG Death City and utilize a simplified 2d6 system focused on thrilling vehicular action and resource management elements such as "High Octane Mode" and "Juice points." This design caters to players interested in cinematic-style tabletop experiences.
In 2021, Polyhedra initiated the Kickstarter campaign for The Plagued Crypt of Helvete, a third-party adventure for Mörk Borg, which was delivered in 2022. That year also saw the release of Tourmaline Valley: Tritonia, a Dungeons & Dragons module authored by Clipper Arnold’s brother, Trevor Dean Arnold. Later Kickstarters for Nebula Chaos (2023) and Toku Legends (2024) broadened their portfolio into science fiction and tokusatsu genres, respectively.
Video Games
Polyhedra introduced a demo for the video game Headcannon in 2023, featuring a robot protagonist equipped with a cannon head. The company has also contributed to game jams, producing titles like the cosmic horror-themed Drifter and the mech-oriented action RPG Project OMEN (2024), which Yahoo Japan highlighted for drawing inspiration from Pokemon and Megaman Battle Network. Furthermore, Polyhedra is involved with the indie boomer shooter CYBRLICH & The Death Cult of Labor. In August 2025, they collaborated on its sequel, Project Omen Arena X Boost.
