Magic Jewelry is an unlicensed game based off Columns, made in 1990 by Hwang Shinwei and published by RCM.
Overview
Magic Jewelry's Gameplay
This game is a basic rip off of Columns, where you have to get rows of three of the same coloured jewelry to clear them and get points. At the end of each level, a column of X blocks appear and whatever colour jewelry it touches, all of them that colour disappear. These also appear when you lose a game. However, it is set in New York as opposed to the Egypt, with the Statue of Liberty taking up a considerable amount of the background graphics. As well as this, the stars and the moon constantly move up the screen for some strange reason, reappearing at the bottom. The background changes colour between levels and the columns move gradually faster, much less rapidly than in Columns. The music changes as well. Like that game, pausing won't make the blocks disappear unlike most puzzle games, making it easier to anticipate the next couple of moves. The graphics in the 2 player mode resemble those from Columns.
Magic Jewelry II
Magic Jewelry II's Title Screen
In 1991, Hwang Shinwei decided to follow up this game with Magic Jewelry II, which adds a menu screen allowing the player to start on any of the first 9 stages, make it so that certain colours of jewelry don't give you points, add a timer if playing in 2 player mode (called Flash for an unknown reason) and turn the music off. There are more music tracks than the original, and there is an indecipherable voice when you start a game. The title screen for this game is ripped from one of Columns' title screens. As well as this, some of the menu graphics are taken from Hatris.
