Classic Kingdom

Classic Kingdom is a series of minigames in Kingdom Hearts Union χ and Kingdom Hearts III. They are simple, two-dimensional video games based on the handheld LCD games popular in the 1980's (the games Mickey Mouse and Mickey & Donald in particular). The games feature Sora and Mickey as main characters, and feature various characters from classic Disney cartoons. There are 25 in total.

Development
Classic Kingdom was first announced in the Classic Kingdom Trailer, shown as part of the Kingdom Hearts Union χ Dandelion Meeting at Anaheim, California in April, 2018. The trailer shows Sora receiving a device from Pence in Twilight Town, followed by a montage of gameplay from the games.

In Version 3.0.0 of Kingdom Hearts Union χ, a selection of five Classic Kingdom games were released as part of χ3. A limited-time challenge is currently being held that rewards players with a code to get the Starlight Keyblade in Kingdom Hearts III by reaching a set total score for each game. In January 2019, the score requirements were cut by half, so that players have a better chance to get the Starlight Keyblade. The promotion is set to run until April 2019.
