U61 is "another block-based game". Its main features are:
The basic rules in U61 are:
These rules are not very precise, and this is what makes U61 different from other block-based games: it is possible to create one's own rules and play with them. This is achieved by creating scripts, using the Lua language.
No! No and No!
U61 is *not* a Tetris(c) clone. Its rules are much more general.
It's true that when I first started the project (in 1999), its name was "Tetr61s" and it was supposed to look much like "EITTris" with network support. Since then, I've had to deal with the so-called "Tetris Company", and realized that cloning Tetris(c) is not possible anymore. So I decided to start a more general project, which name is U61. Of course it's possible to configure U61 so that it looks exaclty like the genuine Tetris(c). But such a configuration is not provided in the standard distribution (inded the "classic" set of rules includes many enhancements).
So Tetris(c) can in a way be considered as a subset of U61, but this does not mean at all that U61 is a Tetris(c) clone.
But if you liked Tetris(c), Columns(c), or Puyo-Puyo(c), then you should like U61, so try it!
