Overview

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.

Components

Setup

  1. Place the two-part Game Board in the middle.
  2. Sort Nobles by reverse-side numbers. From each stack, draw 4 random Nobles; remove the rest. Stack face-down on the Game Board (3s on bottom, then 2s, then 1s). Draw 2 from the top and place on spaces 5 and 4.
  3. Shuffle Gem Cards. Place a number equal to the player count face-up into Stores (by type). Place 2 more than the player count face-up into Bazaar Booths. Remaining cards are the draw pile.
  4. Each player chooses a color and receives a Player Board and 7 Action Cards.
  5. Each player takes 4 Gem Tokens and places them on their Player Board chart.
  6. Stack Gold Tokens randomly; place on space 15 of the Gold Track. Bottom token’s player picks first Gem Card; others follow bottom-to-top order.

Turn Structure

Each Market Day has 3 phases:

1. Replenishing the Market

2. Three Market Rounds

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:

3. End of Market Day

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.

Actions

Purchase (Base cost: 4 Gold)

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.

Sale (Base cost: 2 Gold)

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.

Trade (Base cost: 3 Gold)

Choose one:

Bribe (Base cost: 1 Gold)

Safe from Supervisor losses until end of current Market Day (no fake gems lost from opponent Sales).
