Istanbul is a wonderful puzzle of a board game, and Istanbul: Big Box is the all-in-one package, including the base game as well as both expansions, Mocha and Baksheesh and Letters and Seals, as well as the Istanbul: Caravan Leader Mini Expansion.
 
Istanbul is a gateway-plus strategy game for 2-5 players, based in a bustling Turkish marketplace. Your aim is to collect gems quicker than your opponents.
 
You and your four assistants travel around to adjacent tiles, trading fabrics, spices and fruits for gems, but can you figure out the most efficient route around the stalls to pick up what you need? 
The Mocha and Baksheesh module provides a new trading commodity: coffee. Trade this valuable bean across four new market tiles in different ways to earn gems. 
 
Meanwhile, secrets are the currency in the Letters and Seals expansion. Deliver messages between the market stalls is a neat way to earn money. But even more valuable still is selling those trade secrets for precious rubies 
 
Istanbul: Big Box provides you with a variety of ways to play with a larger bazaar, in a 5x5 grid. This is the perfect way to play with all your Istanbul variants in one big package.
