Play Bust-A-Move 4 Online

Summary

Bust‑A‑Move 4 on the Game Boy Color packs a staggering 640 puzzles into a pocket‑sized cartridge, making it one of the most content‑rich entries in the series. It also introduces two fresh mechanics that change the way you think about bubble‑shooting.
The pulley system links two bubble clusters to a seesaw‑like contraption; popping bubbles on one side lightens it and makes it rise while the opposite side drops. Skilled players can lock the two ends together with a bubble bridge, then carefully triangulate to clear the anchor bubbles without sending the whole pulley off balance.
Chain reactions only appear in head‑to‑head play, letting a single burst cascade across the board as bubbles shift and trigger further pops. The game grades you through a comprehensive ranking ladder—10th Class, 1st Class, 1st Honor, and Expert—so you can see just how deep your skill runs.
Edit Mode lets you craft up to 25 custom stages and save them to the cartridge’s memory, extending replay value far beyond the built‑in catalog. Critics gave the handheld version a mixed but respectable reception, with a 68.60 % aggregate score on GameRankings and a 7.2/10 rating from GameSpot.

Storyline

In Bust-A-Move 4 for Game Boy Color, the story unfolds on the planet Bubbleluna where twin bubble‑blasters Bub and Bob live. One day the sun refuses to rise because the Fairy of the Night, Cleon, has stolen the Rainbow—a magical light source—for the full‑moon ruler Madame Luna. Madame Luna shatters the Rainbow into seven glowing bubbles and scatters them across the world. Determined to bring back daylight, the twins set out to recover each of the seven light bubbles and restore peace.

In the game’s Story Versus mode the player picks either Bub or Bob and follows a linear quest, battling the series’ recurring characters one by one. Each victory brings another fragment of the Rainbow closer to the twins’ grasp. The final confrontation occurs with Madame Luna herself; after her defeat she is revealed to be Dreg, the series’ chief antagonist. With the Rainbow reassembled, the sun rises again over Bubbleluna.
