Alex Kidd in Miracle World (アレックスキッドのミラクルワールド) is a video game released in 1986 by Sega for the Sega Master System console. It is the first of several games in the Alex Kidd series, starring a character which would serve as the company's mascot for half a decade before being replaced by Sonic the Hedgehog.

Alex Kidd in Miracle World stands as one of the more popular Master System releases, having been built into many Master System consoles during the late 1980s and early 1990s. It is also one of the few Master System games to have an official Korean translation. Alex Kidd in the Enchanted Castle may be considered a direct sequel to this game, as it continues the story of Alex's search for his father, King Sander (a.k.a. King Thunder).

The game has since been re-released for the Wii's Virtual Console service.


Alex Kidd is a platform game which bears a superficial resemblance to Nintendo's Super Mario Bros. You play as Alex, the eponymous character who lives on the planet Aries, who is an expert in the martial art of Shellcore, which enables him to break certain blocks and enemies by punching them. These blocks typically contain money, which can be spent on power-ups and extra lives in shops, however some blocks also contain power-ups, or ghosts which follow Alex until he puts enough distance between them.

In some levels, you will be able to use vehicles to assist your progress - the Sukopako Motorcycle, the Peticopter (a pedal-powered helicopter equipped with missiles) and the Suisui Boat. Throughout the game you learn that Alex is a prince of the royal family, who has been usurped by a tyrant named Janken the Great. Your goal is to free the captured royals, and defeat Janken and his henchmen in games of rock-paper-scissors followed by traditional boss fights. In addition, you must collect a series of treasures which will help you bring peace to the kingdom of Radaxian and restore the citizens who were turned into stone.

  • The first release of this game had the actions of buttons 1 and 2 swapped around. It was later changed with its Master System II inclusion to better correlate with other games out at the time.
  • In the Japanese release, Alex collects a rice ball to complete a level and is seen eating it on the following map screen. This was changed to a hamburger in western releases, since rice balls are a food particular to Japan only.
