In Disney’s Aladdin, the Genie grants his master three wishes.
The three-wish limit is explained when the Genie introduces the rules of his magic. He also says there are limits on what he can do: he cannot kill someone, make people fall in love, bring back the dead, or grant a request for additional wishes. These restrictions keep the magic from solving every problem instantly.
Aladdin uses his wishes strategically. His first wish makes him a prince so he can court Jasmine, and his second saves him after Jafar’s guards throw him into the sea. He uses his third and final wish to free the Genie from servitude, fulfilling the promise he made earlier.
The number is sometimes confused with the wider folk-tale tradition, where different versions of Aladdin and genie stories vary. In the 1992 Disney film, however, the rule is explicit: three wishes. The Genie also grants wishes to Jafar after the lamp changes hands.
