Game Comparison

RANDSUM supports six tabletop RPG systems, each with its own dice mechanics and outcome types. Use the comparison below to find the right package for your game.

Every game package wraps the core @randsum/roller engine, so they all share the same reliable dice rolling foundation. The difference is in how each package validates input, configures the roll, and interprets the result.
