Index Card RPG (Master Edition)

Tone ranges from pulpy heroics to scrappy OSR peril depending on how hard you turn the dials. Everything orbits a few elegant dials: Target Number: Each room/scene has a single TN, so all checks point at one difficulty—speeding adjudication.

Theme and Setting

Effort Dice: After a successful check, roll Effort (d4/d6/d8/d10) to make progress on obstacles, enemies, or tasks. This turns locks, monsters, and projects into comparable clocks.

How Play Feels

Hearts: Problems have Hearts (10 HP chunks) that track how much work remains—combat and challenges share the same cadence. Timers & Threats: Countdowns, room effects, and turn structure keep scenes moving and raise stakes without rules bloat.
