Tetris for Game Boy Color. Statistics tracked your best times, and the ghost piece showed where blocks would land.
Tetris DX was developed by Nintendo and released for Game Boy Color in October 1998 — an enhanced version of the original Game Boy Tetris with Game Boy Color support. The game added statistics tracking — recording high scores and line counts — the ghost piece feature that showed a shadow at the bottom indicating where the falling tetromino would land, and three additional game modes including Marathon, Ultra, and VS. The save feature allowed scores to persist after power-off. Tetris DX sold over 2 million copies on Game Boy Color and is considered the definitive Tetris version for the platform.
About this game
Tetris DX (1998) is the definitive portable edition of Tetris for its era — a full-color reimagining of the 1989 Game Boy classic that introduced save data, new game modes, and Game Boy Color-enhanced visuals while preserving the perfect, unfussy gameplay that had made the original one of the best-selling handheld titles of all time. For an entire generation, this was simply the version of Tetris they grew up with.
Key Features
Full color graphics on GBC hardware (also backward-compatible with original Game Boy in monochrome). Marathon, Ultra (score as high as possible in 3 minutes), and 40-Lines (clear 40 lines as fast as possible) modes join the classic marathon. Save system records high scores and game progress. Two-player versus via Game Link Cable. The new color palette varies by level, giving visual feedback on progress.

The Story Behind
The original Game Boy Tetris (1989) had defined what a handheld game could be — a pure, portable, endlessly replayable experience bundled with the hardware itself. Nine years later, Tetris DX arrived as the Game Boy Color launched, serving as the GBC's own pack-in identity piece. Where the 1989 version was monochrome and barebones by necessity, DX used color and save features to refresh the formula for a new generation of portable players without altering what made Tetris timeless.
Tricks & Tales
Tetris DX was bundled with some Game Boy Color hardware packages, echoing how the original Tetris had been bundled with the Game Boy itself in 1989. The game supports "Super Game Boy" display on Super Famicom — meaning it can show color frames and enhanced borders when played through the SGB adapter, bridging three Nintendo hardware generations. High scores are saved to battery-backed RAM, which means aging cartridges may lose records as the battery depletes.
Collector's Guide
Region & Compatibility
Released worldwide. Japan version (テトリスDX) and Western versions are functionally identical. The game is backward-compatible with original Game Boy hardware.
Maintenance Tips
The battery-backed save RAM will eventually deplete, erasing high scores. A common repair is replacing the CR2025 coin cell inside the cartridge — requires a special Game Boy security screwdriver (3.8mm). Clean contacts with isopropyl alcohol before attempting any battery replacement.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Tetris DX copies regularly.
Is this a region-free game? Will a Japanese Game Boy cartridge work on any Game Boy console?
Yes. The original Game Boy, Game Boy Pocket, and Game Boy Color have no hardware region lock — a Japanese cartridge plays on any Game Boy or Game Boy Color console worldwide without modification. The game itself is in Japanese, but the hardware accepts it freely. Game Boy Advance consoles are also backward-compatible with Game Boy and Game Boy Color cartridges and share this region-free status.
How should I clean a Game Boy cartridge?
Apply 90% or higher isopropyl alcohol to a cotton swab and gently wipe the gold-plated edge contacts on the base of the cartridge. Never blow into the cartridge — breath moisture accelerates contact corrosion. If the shell needs to be opened for deeper cleaning, Game Boy cartridges use 3.8mm security game bit screws. The contacts are small; clean with a gentle wiping motion rather than abrasive pressure.
Before You Buy
Things worth knowing before you buy Tetris DX
A short checklist for buying a used Game Boy Color cartridge wisely — useful with any seller, anywhere.
-
Choose a seller who tests it before shipping
A copy that has actually been powered on and checked is a known quantity. An untested one is a gamble you only settle after it arrives.
Look for a seller who states it was function-tested and says what they confirmed. A serious seller can tell you exactly what was checked.
-
Good news — Game Boy Color is region-free
These cartridges are not region-locked, so a Japanese copy plays on any compatible Game Boy worldwide.
Confirm whether the title is Color-only or also works on the original Game Boy.
-
If this title saves your progress, check the battery
Cartridges that save use a small coin-cell battery that fades over decades — a dead one wipes your save without warning.
Ask the seller whether the save function was tested. Replacing the battery is possible, but doing so erases any existing save.
-
Check that the contacts are clean
Dirty edge contacts are the most common cause of startup and sound trouble in cartridges of this age.
Choose a seller who cleans the contacts before shipping. A note that it was tested and cleaned means the basics were handled.
-
Read the seller's reviews and return policy
A 100% positive record across thousands of sales is close to a guarantee — packing, communication and problem-solving all work for everyone. A return policy protects you if something is off.
Read the feedback and confirm a clear return window before you buy.
The last step before buying anywhere is knowing what it's worth.
