Variants and The Great Bazaar
Istanbul's Big Box variants: Random Layout, Neutral Assistants and The Great Bazaar with both expansions in a 5 × 5 grid.
These variants come with the Big Box rulebook and can be combined freely.
Random Layout
- Shuffle the Places and lay them out.
- The Fountain must be an inner Place; swap it if needed.
- The Black Market (8) and the Tea House (9) must be at least 3 Places apart and not in the same row or column; swap Places if needed.
Neutral Assistants
For experienced players:
- At setup, replace the bottom Assistant of each stack with an Assistant of a neutral colour (for instance white).
- Ending your move on a Place with a neutral Assistant, you may pick it up as if it were yours. If one of yours is there too, choose which one to pick up.
- You may carry several neutral Assistants.
- At the Fountain you only call back your own Assistants.
The Great Bazaar
Base game plus both expansions — for players who know them well.
- Lay out Places 1–25 at random in a 5 × 5 grid, the Fountain in the centre.
- The Black Market and Tea House rule above applies (at least 3 apart, different row and column).
- Use all Bonus cards; all base and expansion rules apply.
- The Tavern’s Encounter tile also covers the Courier. The Secret Society may also take a Ruby from the Coffee House.
- Coffee beans printed on Letters, Kiosk tiles and cards only matter in this variant: there, coffee is an option wherever it is shown.
