Play Uno - Small World (Japan) Online
Slap down pixelated cards on a tiny Game Boy screen—same Uno chaos, now with that crunchy handheld charm and ruthless AI opponents. Link cable play works if you’ve got a friend still clinging to their old hardware.

Uno: Small World for the Game Boy, released in 1998 by Nintendo, is a portable adaptation of the classic card game. It arrived late in the system's life, offering a straightforward digital version of Uno you could take anywhere. The game was developed by TOSE and published by Nintendo, fitting neatly into the library of simple, pick-up-and-play titles that defined the handheld.
You play against up to three computer opponents, aiming to be the first to discard all your cards by matching colors or numbers. The core mechanics involve drawing cards when you cannot play, using action cards like Skips and Reverses to disrupt opponents, and shouting "Uno" when down to your final card. The pacing is quick, though the AI can be surprisingly aggressive, making wins feel earned. It captures the tension and sudden shifts of the physical game well, even on a small monochrome screen.
