Points are rewarded for picking locks and finding treasures.
To achieve these tasks, the player has to solve mathematical riddles while using the four basic arithmetic operations.
The answer has to be typed in by using the keyboard.
If the player doesn't succeed, the game shows the correct answer and another attempt has to be made - but in a few cases the treasure gets stolen by a spider and is lost forever.
In the beginning of each round the player selects the size of the castle and the used combinations of mathematical operations, e.g. only addition or multiplication and division.
About Atari 2600
The Atari 2600 (1977) was the console that first proved interchangeable game cartridges could sustain a mass-market business, effectively founding the home console industry as we know it. Most common 2600 titles are inexpensive today given how many units and copies were sold, but a small number of extremely rare releases — including several from Atari's own late-era prototype and licensed titles — are among the most valuable cartridges in retro collecting.
Gamevaro tracks Adventures on GX-12 for Atari 2600 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 Adventures on GX-12 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 A2600 release dates back to 1988.

Market insights
Rarity & condition
Only a handful of market sales have been tracked for Adventures on GX-12, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Atari 2600 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.
