Rainbow Islands

The sequel to Bubble Bobble , Rainbow Islands sees Bub and Bob who were turned into human form at the end of its predecessor, attempting to rescue the inhabitants of the titular Rainbow Islands from the evil Boss of Shadows.

Instead of bubbles, Bub and Bob now have the power to cast rainbows, that can be used to directly destroy baddies or trap them underneath.

The Nintendo Entertainment System (1983 in Japan, 1985 in the West) revived the North American video game industry after the 1983 crash and established conventions — cartridges, licensing seals, save systems — that shaped the industry for decades. NES collecting is one of the most established retro markets: common titles remain cheap, but a well-known handful of low-print-run games (many from smaller third-party publishers) are among the most expensive video games in existence.

Gamevaro tracks Rainbow Islands for Nintendo Entertainment System 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 Rainbow Islands 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 NES release dates back to 1987.

Market insights

Rainbow Islands has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.

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.
