About this game

In The Flintstones: King Rock Treasure Island , Fred Flintstone finds a treasure map during work.

In order to find said treasure, he needs to solve seven levels, some ending with a boss battle.

These are traditional side-scrolling platform levels in which Fred has to jump over gaps and dodge enemies.

His weapon of choice are axes which he throws at an angle.

However, hitting an enemy does not kill them instantly but stuns them; a state where they can be abused as stepping stone.

Hitting them while they are stunned kills them, but they respawn when Fred walks back to their starting location or at special skulls - those are mostly placed at sections where Fred can't progress without an artificial staircase.

Of course there are also power ups to collect: most of them only increase the points counter or refresh the life energy, but one allows Fred to ride his pet dinosaur Dino.

This allows him to throw axes straight and jump higher, but Dino is lost when hit once.

About Game Boy

The original Game Boy (1989) proved that handheld gaming didn't need cutting-edge graphics to succeed — its monochrome screen and legendary battery life, combined with Tetris as a pack-in, made it a cultural phenomenon. Game Boy cartridges are famously durable, so this remains one of the more accessible retro platforms to collect, though translucent color variants and complete-in-box copies with the original brick-sized manual add real value for condition-focused collectors.

Gamevaro tracks The Flintstones: King Rock Treasure Island for Game Boy 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 The Flintstones: King Rock Treasure Island 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 GB release dates back to 1993.

Rarity & condition

Only a handful of market sales have been tracked for The Flintstones: King Rock Treasure Island, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Game Boy 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.
