So, to try to bring TETREVIL to a new and possibly more familiar setting, I've made a TETREVIL mode for NullpoMino. http://www.tetrevil.org/tetrevil_nullpo.jnlp is the direct link, or you can click "evil nullpomino" on the nav bar at the top of www.tetrevil.org. I think it's pretty spiffy. It works with the 7.5.0 NullpoMino binary, as well as the 7.6 developmental version. If you're running 7.6 you also can play multiplayer TETREVIL; 7.5 doesn't support multiplayer modes so no dice for the people running the normal distribution I'm afraid. There are current four settings for TETREVIL mode: aggressive, evil, fast aggressive, and fast evil. Aggressive and evil match the difficulty of their similarly named web client versions. The "fast" randomizers reduce the ARE delay by computing the next piece to give you while you are still choosing where to put the current one, which makes them slightly dumber (because they can make incorrect assumptions on incomplete data) but possibly more enjoyable to play. As usual, the AI is smarter, etc..
