About Atari 7800
The Atari 7800 (1986) was designed as a technical successor to the 2600 with backward compatibility for that console's cartridge library, but it launched years after being developed and struggled against the NES's dominance. Its brief commercial window means a relatively small original-game library, making complete 7800-exclusive titles a niche but approachable part of classic Atari collecting.
Gamevaro tracks Klax for Atari 7800 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 A7800 release dates back to 1990.

Rarity & condition
Only a handful of market sales have been tracked for Klax, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Atari 7800 titles.
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.
