Overview

12 Thieves (originally published as The Thief of Baghdad) is a hand-management and area-control card game where players send thieves to steal treasures from six palaces in a bazaar. Players play palace cards to place thieves, move guards, and manipulate the board. When enough thieves gather at a palace, the controlling player steals a treasure chest. The first player to collect a target number of treasures wins.

Components

Setup

  1. Place the gameboard in the center of the table.
  2. Place 1 black neutral guard before each palace.
  3. Arrange treasure stacks at each palace (top chest shows 4, then 5, 6, 7 underneath).
  4. Distribute guards based on player count:
    • 2 players: 4 guards each
    • 3 players: 3 guards each
    • 4 players: 2 guards each
  5. Players alternate placing their guards on palaces (1 at a time).
  6. Deal starting cards based on player count and turn order:
    • 2 players: 6 and 7 cards
    • 3 players: 6, 7, and 8 cards
    • 4 players: 6, 7, 8, and 9 cards
  7. Oldest player goes first.

Turn Structure

On their turn, a player may perform up to 3 thief-related actions (placing thieves or stealing). They may also move guards. Then they draw cards.

Actions

1. Place a Thief

Play palace cards matching the target palace. You need 1 card per neutral or opponent guard in front of that palace. Place 1 thief at the palace.

2. Move Your Own Guard

Play 1 card matching either the guard’s current palace or its destination. The destination must have an open guard space.

3. Move a Guard with a Thief

Play 1 card matching the current or destination palace. Move both the guard and an accompanying thief together.

4. Move a Neutral Guard

Play 2 cards: 1 matching the guard’s current palace, 1 matching its destination. The destination must have an open guard space.

Stealing Treasure

When the number of your thieves at a palace equals or exceeds the number shown on the top treasure chest, you steal it. Remove your contributing thieves from the board and take the chest. The next chest (requiring more thieves) is revealed.
