NullpoMino is a cross-platform, open-source Tetris fan game notable for variety of gameplay modes and customizability. It is a Tetris clone written in Java providing three versions: One using Slick, another using sdljava, the last using Swing. It was created by NullNoname. It simulates numerous games, including the TGM series, and contains a utility for creating (and editing) your own custom rotation systems as well.
NullpoMino is one of the few Tetris games, official or not, with a truly cross-platform online vs. mode, the others being TetriNET, Blockbox, Tetris Friends, and MultriNet. Blockles also would have been on this list before its demise.
 Game Modes
All of the game modes with "Mania" in their names are based directly on TGM modes, except for the two added by Zircean: Retro Mania simulates Sega Arcade Tetris, while Phantom Mania takes the Death speed curve and makes it invisible.
- Marathon: Guideline 15/20 level Marathon with fixed Goal system
- Marathon+: Survival mode from Tetris Friends. It has semi-invisible bonus challenge at level 21.
- Extreme: Plays like Master mode from Tetris Zone. A 20G mode with guideline scoring rules.
- Line Race: A 40 line game. The goal is customizable from 20, 40, and 100 lines.
- Score Race: Race to specific points (10000, 25000, or 30000). Plays similar to Tetris Evolution's Score mode.
- Dig Race: Break the bottom of 5, 10, or 18 lines of garbage as fast as you can.
