Jewelry Master is a non-Tetris game for Windows PCs which was released by Arika, known for its TGM series of games. While having different rules than Tetris, the game carries over many prominent gameplay features from TGM, such as IRS and 20G. This wiki entry is based on the beta release on November 24, 2006. The beta test is limited to 5000 participants, less than 1000 of which are currently taken. Jewelry Master is expected to release in December, and will be localised in English for Western markets.

Version Update

The November 24 version of the game, v1.07, will become inaccessible as of November 30. The new version, v1.10, will be available for download on the same day. With the update the ranking board will be cleared.

Gameplay Basics

The general idea is to combine gem colours to create diamonds which you then clear in a large combo. Learn the rules of the game to help you accomplish this.

Segmented Pieces

Main article: Tetromino#Multimino

Rather than always coming as a solid whole, pieces are often split into segments. While you are moving a piece it behaves as a solid group, though once the piece locks its segments will detach and fall if possible.


Lines must be composed entirely of blocks, not gems. Unlike Tetris, each piece segment that is part of the line will entirely disappear, even the bits that are not part of the line.

Enclosing the Gems

To enclose a gem, it must be completely surrounded in a section that is cut off from the top of the screen by any path. Note that enclosure allows for diagonal holes, so you only have to fence in the top, bottom, left, and right of the area the gems are located.

Combining Gems

Enclosing gems of different colors will create a new color. Clearing primary colored gems (red, green, and blue) yield the least points. Combining two of these will create a secondary colored gem of either cyan, magenta, or yellow. Clearing these yield more points than clearing primary gems. Enclosing all primary colored gems (by a combination of primary and/or secondary and/or diamond) will create a white gem (diamond), which is worth the most points when cleared.

Clearing Gems

If you enclose gems and they are all of the same colour they will clear. In fact, this causes all gems of that colour to clear even if they are outside the enclosure.

Game Modes

Jewelry Master features 3 game modes. Unlike TGM the goal is not a rank attack or time attack to level 999 but a score attack.

Normal Mode

Pieces fall at speeds similar to TGM's Master Modes. Gems here do not ever fuse and instead behave as individual blocks.

Hard Mode

Plays just like normal mode, except same-coloured gems will fuse together to form a larger solid irregularly shaped gem.

Death Mode

The fastest mode, starting immediately at 20g. Gems fuse together as in Hard Mode.
