The Dice Lab

The Dice Lab is a dice design project associated with Robert and Henry Segerman. Its official pages document specialty polyhedral forms, including skew dice and truncated-tetrahedron d4s, as well as standard RPG set formats. The brand is useful for documenting the distinction between a die’s geometry, numbering, and intended outcome range. Design claims and any probability discussion should be attributed to the specific Dice Lab page and evaluated separately from a general brand description.
