JB: an open-world game on the real map of Iran
JB (Jahanbaz, “open world” in Persian) is a free game that runs right in your browser, on phones and computers, with nothing to install. Its world is built from real map data: all 22 districts of Tehran with about 1.2 million buildings, and the cities of Shiraz, Rasht, Bandar Anzali, Yazd, Meybod and Bushehr, connected by the highways of Iran.
Walk the streets, drive Iranian cars like the Peugeot 405, Pride and Paykan, fly airliners out of Mehrabad, ride a lenj boat on the Persian Gulf, or meet friends online.

Cities and landmarks
- Tehran: Azadi Tower and square, Milad Tower, Tabiat (Nature) Bridge, the Grand Bazaar, Golestan Palace, Valiasr Street with its plane trees, Azadi Stadium and Mehrabad Airport
