NullpoMino is a cross-platform, open-source fan game written in Java providing three versions: One using Slick, another using sdljava, the last using Swing. The game also simulates many Tetris games, as well as the TGM series and a few fan games, and also contains a utility for creating your own custom rotation systems.
NullpoMino is one of the few Tetris games, official or fan-made, with a truly cross-platform online versus mode.
As of version 7.5.0, NullpoMino contains the following modes:
- Marathon – Fixed-goal mode. The player can choose between 150 Lines, 200 Lines, or Endless.
- Marathon+ – Based on Tetris Friends' Survival mode. Fixed-goal (200 Lines) mode with a steeper gravity curve and an Endless semi-invisible round after reaching Level 21.
- Extreme – Marathon mode with 20G and lock delay decreasing per level. Endless can be toggled on.
- Technician – Variable-goal Marathon mode. Five difficulties are available:
- LV15-EASY – Standard speed curve. Bonus points are given in the first 2 minutes of each level.
- LV15-HARD – The game ends when the 2-minute level timer runs out.
