Play Bust-A-Move 4 (mono hack) Online
You shoot bubbles up the screen in black and white, watching chains collapse as the board creeps closer—somehow even more satisfying without color. That old Game Boy pea-soup screen makes every combo feel like a secret win.

Bust-A-Move 4 for the Game Boy Color was released in 2000, developed by Taito. It arrived late in the handheld's life, offering a straightforward puzzle experience without much fanfare. The game fits neatly into the era's portable library, where simple, repeatable mechanics often trumped visual spectacle.
You control a bubble launcher at the bottom of the screen, aiming and firing colored bubbles upward to match groups of three or more. The main goal is to clear the board before bubbles descend too low. Key mechanics include banking shots off walls for tricky angles and creating chain reactions by popping supporting bubbles. The pace is methodical but tense, especially as the ceiling drops. It feels satisfying to watch a well-planned shot unravel a crowded screen.
