Shanghai II

Shanghai II is a variant of the puzzle game also known as solitaire mahjong. 144 mahjong tiles are arranged in rows and stacked upon each other in various patterns; the player's goal is to remove pairs of matching tiles that do not have adjacent tiles from both sides until the whole board is clear.

This variant features six patterns named after animals: tiger, scorpion, monkey, snake, panther, and dragon.

Sega's Game Gear (1990) was a technically capable handheld competitor to the Game Boy, notable for its full-color backlit screen — a real advantage at the time, offset by famously poor battery life. Its commercial underperformance against Nintendo's handheld means smaller print runs overall, and complete, well-preserved cartridges (the plastic shells are prone to yellowing and cracking) are a genuine niche within retro handheld collecting.

Gamevaro tracks Shanghai II for Sega Game Gear 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 Shanghai II 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 GG release dates back to 1993.

Market insights

Shanghai II 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.
