Rainbow Islands is the legendary arcade platformer ported to the Famicom by Taito, sequel to Bubble Bobble. Players control Bubby and Bobby, creating rainbow arcs to defeat monsters, climb platforms and transform foes into collectible treasure. The title features multiple themed island worlds, secret item systems and several distinct endings based on treasure collection, cementing its reputation as a beloved arcade classic adapted for 8-bit consoles.
Each island consists of stacked horizontal stages. Generated rainbows act both as attack weapons and temporary climbing surfaces. Defeated enemies convert into gems and power-ups. Collecting specific hidden treasures unlocks extended final stages and the true canonical ending.
Single-player mode progresses through increasingly difficult island layouts. Simultaneous two-player co-op enables coordinated rainbow attacks against monster swarms. Losing a life resets collected treasure progress for the current island.
Taito’s Famicom port faithfully recreates arcade rainbow physics and monster behaviour. Cheerful melodic looping background music maintains lighthearted fantasy island atmosphere throughout the treasure hunt.
Strategically, optimal completion prioritises gathering required hidden treasure sets before defeating island bosses. Skipping treasure collection locks players out of the extended true ending sequence.
Culturally, Rainbow Islands belongs to Taito’s iconic Bubble Bobble franchise. For modern retro arcade platform collectors, this Famicom port represents essential bubble-era arcade heritage with its creative rainbow traversal mechanic.
