Rules of Arcanum
A trick-taking duel of seals & sleight
The goal
Lose the fewest seals
Three players, fifteen tricks per round, three rounds per match. Each seal you fail to discard at round's end costs you 3 points. The sorcerer with the highest score wins.
Phase I — Bidding
Take seals from the central pool, one at a time, choosing colors you intend to win tricks in. When the pool is empty, you may steal seals from rivals — but they receive a white joker in return (worth −4 if unspent). Pass when ready.
Phase II — Tricks
Lead any color. Others must follow if able. Red is trump and beats all. Highest card of the lead color (or highest red) takes the trick.
Standard winDiscard one seal of the winning color.
Red trump winDiscard one red seal — or one of the lead color.
Joker decisionSpend a joker to discard nothing.
No matching sealTake a black seal: −3 points.
Scoring
−3 per leftover colored seal · −3 per black seal · −4 per unspent joker. Match score is the sum of three rounds.
