Rules: entrants roll a d66 (a pair of d6's, with one being the 10's place and the other the 1's place) on "Roll 1". If a rolled result states to "roll on Roll 2", make a roll on "Roll 2"; otherwise, IGNORE Roll 2.

Entrants may reroll their results, but this is discouraged unless the mechanics genuinely don't work well together.

Some results on Roll 1 are "challenge" results that are additional design constraints. If an entrant gets a challenge result, they roll Roll 1 a second time (or choose it manually), ignoring additional challenge results.

While this is intended to be an RPG jam, other types of games are welcome.
