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.
Clone of the Flash game Happy Pill. The player must aim a pill to hit frowning faces until they smile; if the pill hits the same face too many times, it will disturbingly "die" and turn into a skull. A VT368 hack of the game was also produced (under the same name). Later re-published by Waixing; the Waixing version uses a weirdly off-putting rendition of the theme to Gentlemen of Fortune, a Soviet comedy film.
