Play Gem Gem Monster (Japan) Online
You match gems to power up your little monsters, then toss them into battle—it’s got that perfect mix of puzzle-solving and chaotic creature mayhem. Those deranged little guys growling at you while you line up combos? Weirdly addictive.

Gem Gem Monster is a Japan-only Game Boy Color release from 2000, developed by KID. It arrived late in the system's life, offering a distinct puzzle-battler experience that felt different from the more common platformers and RPGs of the time.
You control a team of monsters, matching colored gems on a grid to power them up before sending them to fight opponents on the adjacent screen. The main goal is to clear each stage by defeating enemy monsters through strategic gem alignment and timely attacks. Key mechanics include chaining combos for bigger attacks and managing a small roster of creatures with unique abilities. The pace is methodical but tense, especially when the opponent's monsters close in. It feels satisfying to set up a big combo and watch your creatures unleash chaos.
