Prince of Persia online playable MS-DOS game

How to play Prince of Persia Online

Prince of Persia MS-DOS game is set in ancient Persia. While the sultan is fighting a war in a foreign land, his vizier Jaffar, a wizard, seizes power. His only obstacle to the throne is the Sultan’s daughter (although the game never specifically mentions how). Jaffar locks her in a tower and orders her to become his wife, or she would die within 60 minutes (extended to 120 minutes in the Super NES version, which has longer and harder levels). The game’s unnamed protagonist, whom the Princess loves, is thrown prisoner into the palace dungeons. In order to free her, he must escape the dungeons, get to the palace tower and defeat Jaffar before time runs out. In addition to guards, various traps and dungeons, the protagonist is further hindered by his own doppelgänger, conjured out of a magic mirror.

The main objective of the player is to lead the protagonist out of dungeons and into a tower before time runs out. This cannot be done without bypassing traps and fighting hostile swordsmen. The game consists of twelve levels. The DOS version allows the player already in the very late part of Level 12 to continue after time is out with no extra life.
