Nintendo Mini Classics — Game & Watch in Keychain Form
The Nintendo Mini Classics, released in 1998, were miniature keychain-sized recreations of classic Game & Watch titles — tiny versions of games like Donkey Kong, Mario Bros, and Octopus in a form factor small enough to hang from a keychain. Released to coincide with the 18th anniversary of the original Game & Watch series, the Mini Classics brought the classic LCD gameplay to a new generation while serving as nostalgic collector’s items for those who had played the originals. Their tiny size and keychain format made them popular accessories, and complete sets of Mini Classics are today sought-after collectibles in their own right.
