The Nintendo Game & Watch Gold Cliff — Mountain Climbing Adventure
The Nintendo Game & Watch Gold Cliff, released in November 1988, was one of the final Multi Screen Game & Watch models — featuring a mountain climber navigating a cliff face across two screens. By late 1988, the Game Boy’s development was nearly complete, and the Gold Cliff was among the last Game & Watch releases before Nintendo shifted its handheld focus to the cartridge-based platform. The Gold Cliff’s late production date makes it one of the scarcer Multi Screen models, and its distinctive adventure theme differs from the more arcade-based titles that dominated the earlier Game & Watch catalogue.
