About
Tetris is a puzzle game built around stacking falling blocks to clear lines, based on Alexey Pajitnov's 1985 original. NullpoMino is an open-source Java action puzzle game with many single-player modes and netplay over the Internet or LAN. The current stable version, 7.5.0, has a Windows installer, a macOS app bundle, a Linux package and a cross-platform zip.
How it differs from the original
It adds Internet and LAN netplay and many single-player modes, including a "Dig Challenge" mode where garbage blocks keep rising.
