Istanbul

The original supports two to five. Build a 4×4 bazaar; start at the Fountain with four assistants, keeping a fifth aside.

The random first player starts with two Lira; later players receive one more each. Draw one Bonus card. Two-player games add neutral merchants at both Mosques and the Gemstone Dealer.

Turns proceed clockwise through movement, merchant encounters, action, then other encounters.

Normally move the whole stack one or two orthogonal steps, finishing at a different location.

Collect your assistant there or leave one. Otherwise end the turn; the Fountain is exempt.

Pay two Lira per other merchant or end your turn. Fountain visits are free; neutral fees enter supply, then dice relocate them.

Use or skip the location action. Warehouses fill capacity; markets follow demand; Bonus cards obey their timing.

Wheelbarrow extensions cost seven; the third awards a ruby. Mosques require showing the depicted stock but spending one good; a matched mosque pair awards a ruby.

Pay the Palace or Dealer requirements for their next ruby; later costs rise. The Fountain retrieves any number of your assistants without needing one locally.

Five rubies trigger the final round, six with two players. Finish that round and play remaining goods/money Bonus cards. Most rubies wins; ties compare Lira, goods, then Bonus cards, before sharing victory.
