Johari is set in the famous jewelry market of Jaipur. Players are gem traders acquiring collections of gems from stores and bazaar booths, then selling them to jewelers and collectors for prestige. The game is played over 10 Market Days, each consisting of 3 Market Rounds where players simultaneously select actions. The player with the most Prestige Points at the end wins.
Each Market Day has 3 phases:
In each round, players simultaneously play a face-down Action Card in the leftmost open slot of their Player Board. All reveal simultaneously. The player with the most Gold acts first (tiebreak: Gold Token on top).
Action costs are modified by Player Board slot:
Take back all played Action Cards. If you played Trade, add those stored cards to your display. Gold Cards from Trade may be used immediately.
Take all cards from one Store or one Bazaar Booth and place face-up in your display (sorted by type). Gold Cards can be used immediately or kept as wild cards for selling. Prestige Cards may be kept face-down.
Sell gems to Jewelers or Collectors:
Jeweler: Sell 4 different gem types (or 3 different + 1 Gold Card). Choose one sold card; advance that Gem Token on your Prestige Track by the number of gems depicted on it. Discard all sold cards. You may sell fake gems.
Collector: Sell gems of a single type, but only if another player also has that type AND you have the most gems of that type. Advance your Gem Token by the difference between your count and the second-most player’s count.
After each Sale action, all opponents must discard one fake Gem Card (Supervisor Symbol) from their display.
Choose one:
Safe from Supervisor losses until end of current Market Day (no fake gems lost from opponent Sales).
Swap one of your Gem Cards with another of the same type from a Store or Bazaar Booth. Cannot exchange cards from a Trade Action Card.
Repeat the action of your previously played Action Card. Cannot be played in the first Market Round of a Market Day.
Receive 2 Gold (move Gold Token forward 2 spaces).
The game ends at the end of the Market Day in which the last Noble enters the Market.
Final Scoring: Add up Prestige Points from:
The player with the most Prestige Points wins. Tiebreak: highest sum of Gem Tokens on the Prestige Track.
