Two copies of the same mind in a nine-number world. They take turns chasing and running, and each one invents new exploits and patches the ones used against it. The game never ends.
Solid disc chases, hollow disc runs. Every tag, slip, copy-out or stall flips the chase.
| Exploit | A attacks | B defends | B attacks | A defends | Patch |
|---|
Fixed roles: a faster cop (Shield) against a robber (Sword) that climbs a ladder of exploit classes. Each Shield patch closes one class. The number is the Sword's win rate over 200 Jesse-vs-Jesse episodes.
