Uno

Uno is a 2001 Macintosh adaptation of the classic Mattel card game, written by Mikael Bergerholm and last released as version 1.3 for Mac OS 8 and 9 on PowerPC. Players race to discard their entire hand by matching colors or symbols, with leftover cards counted as penalty points at round's end, faithful to the family card game's rules.

Game basics

UNO sits squarely in the Crazy Eights family. Each turn a player must lay down a card matching the discard pile's color or rank, drawing from the stock if they cannot. Action cards reverse turn order, skip the next player, or force draws, while the wild cards let a player pick the active color.

Origins

The original UNO was created by barber Merle Robbins in Reading, Ohio in 1971 and has been owned by Mattel since 1992. Bergerholm's Macintosh version brings that exact ruleset to the desktop in a tidy single-window interface.

Platform requirements

The build is PowerPC-only and targets Mac OS 8-9. It will not run natively under Mac OS X without Classic, so today the easiest route is SheepShaver or another Classic Mac emulator.

Version history

The Macintosh Garden listing surfaces version 1.3 as the latest release, dated 2001. There is no newer Carbon or OS X build.
