Boulderdash
Commodore 64 · 1984
About this game
his classic game is about a diamond chase underground with many obstacles.
Try - as Rockford - to collect all required diamonds in a total of 16 caves (A-P) each with 5 difficulty levels, and find the exit in the time given.

After every 4 caves (D, H, L, P) follows a so-called "intermission", a logical puzzle (without its own "cave letter").
Rockford can dig through the ground and push rocks.
But these can also be dangerous.
If he stands directly below a rock, Rockford can hold it on his head.
But if a rock falls on his head, it will cost him a life.
Rocks will not stay on each other or on walls.
If Rockford digs away the supporting soil, rocks will start to slide.
Furthermore, there are some not-so-friendly animals such as fireflies, amoeba and other things you'd better not touch.
Butterflies and other inhabitants of the underground can only be defeated by letting rocks fall on them.
When defeated, they turn into diamonds, which Rockford can pick up.
As soon as the necessary amount of jewels has been collected (the number is shown in the upper bar), the escape tunnel opens into the next level.
Strategy and thoughtful planning is the basis to master this game.
About Commodore 64
Released in 1982, the Commodore 64 is the best-selling home computer model of all time, with an enormous software library spanning games, productivity tools, and everything in between. C64 game collecting centers on cassette tapes and floppy disks in their original packaging — physical media that's inherently fragile, so complete, working copies from the era are increasingly prized by retro computing collectors.
Gamevaro tracks Boulderdash for Commodore 64 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 Boulderdash 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 C64 release dates back to 1984.

Rarity & condition
Only a handful of market sales have been tracked for Boulderdash, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Commodore 64 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.
