The Game Boy version of Tetris was the first game compatible with which accessory?

The Game Boy version of Tetris was the first game compatible with Nintendo’s Game Link Cable. The accessory connects two Game Boy systems, allowing compatible cartridges to exchange data and support multiplayer features.

Nintendo’s 1989 Tetris release used the cable for its two-player mode. Each player had a separate Game Boy and Tetris Game Pak. Players competed to survive longer, and clearing multiple lines could send incomplete rows to the opponent’s field, making the stack rise and increasing the pressure.

The cable was introduced alongside the original Game Boy and became one of the system’s defining accessories. It was not the Transfer Pak, which was designed for later Nintendo 64 connectivity, nor the Rumble Pak, which added vibration to some Nintendo 64 games. The Super Game Boy was an adapter for playing Game Boy cartridges on a television through the Super Nintendo.

The Game Link Cable’s importance extended beyond Tetris. Later Game Boy games used it for head-to-head matches, trading creatures or items, cooperative play and other data transfers. Tetris helped demonstrate immediately why a portable system could benefit from a physical multiplayer connection.
