マジカルドロップ

Magical Drop is a 1995 competitive arcade puzzle game created by Data East Corporation. It is the inaugural game of the Magical Drop series. Magical Drop is based on a game called Drop-Drop created by Russ Ltd, a Russian company.

The arcade game received an updated version named Magical Drop Plus 1! that features aesthetic improvements and also introduces a "Solo Play" mode. Magical Drop Plus 1! was released in North America and Europe as Chain Reaction; in this version, the puzzle pieces are changed from spherical Drops to various items (such as food or celestial bodies) and the character-unique voice acting is replaced by a single male narrator.

All versions of the original arcade game were developed for Data East's "MLC" arcade hardware.
