U61 in a nutshell
U61 is "another block-based game". Its main features are:
- Network play. Gameplay should be fast even with poor bandwidth. Local multiplayer game is also available.
- Theme support. The graphics and sounds are fully configurable.
- Rules customization. As it uses Lua scripts, the game rules can be changed by any player, without having to modify any complex C++ code.
- Cross-platform support. Since it is based on ClanLib, U61 runs on any platform supported by ClanLib (GNU/Linux, Windows...).
Basic rules
The basic rules in U61 are:
- The player has a map, and blocks fall int it. Blocks are made of colored squares.
- The player may control the block as it falls, for instance rotate or translate it.
- When the block lands at the "bottom" of the map, ie when it can not fall any more, it is merged with the map.
- When a given pattern is matched in the map, for instance, squares of the same color, then these squares explode and disappear.
- There's always a special square on the map, and when this square explodes, a "curse" is activated. Curses can be anything from bonus to maledictions.
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.
Hey, but this is a Tetris clone!
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!

Jimmy Kaplowitz wrote the "unstable" curse, and is currently works on Debian support for U61 - which is not an easy task since U61 has a bunch of dependencies 8-)
