Klax

An action/puzzle game, the object is to catch assorted color falling tiles and create rows, columns, or diagonals of a single color.

Each level requires a different pattern to be made, and the tiles fall faster, more at a time, and in an increasing number of colors as the game progresses.

The Game Boy Color (1998) added a color screen to the original Game Boy formula while remaining backwards compatible with the entire existing cartridge library. Its colorful, semi-transparent cartridge shells make it a visually distinct platform for shelf collectors, and several late-cycle exclusives — released just before the Game Boy Advance took over — are notably harder to find complete today.

Gamevaro tracks Klax for Game Boy Color with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding Klax to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GBC release dates back to 1989.

Market insights

Klax has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
