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.
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.
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.
Play 1 card matching either the guard’s current palace or its destination. The destination must have an open guard space.
Play 1 card matching the current or destination palace. Move both the guard and an accompanying thief together.
Play 2 cards: 1 matching the guard’s current palace, 1 matching its destination. The destination must have an open guard space.
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.
Dancer cards are wild — they can substitute for any palace card.
The first player to collect the required number of treasures wins:
