Free tetris 0.9 software for linux

Hextris is Tetris with stones made of hexagons.
It takes some time to get used to the hexagon board but its worth it.
Main features:
- severity levels for beginner, medium and expert
- choosable speed at game start
- global highscore list
- choosable hexagon size
- Java/multiplatform implementation
- GPL license
The aim of the game is to score as high as possible. So here are some score hints:
- Moving down stones manually scores more than waiting until stones move automatically.
- Playing in higher levels scores more than playing in lower levels. If you start in a higher level then you stay there as long as it takes to reach that level from level 1. So if you feel comfortable in say level 3 then its better to start in level 3.
- The score for removed lines depends on the number of simultaneously removed lines and grows quarely, i.e. filling 2 lines with one stones brings 2 times the score of filling 2 lines seperately. 3 times for 3 lines etc.
The actual number of score points can be found in the help display

Vertris project is a simple cross-platform Tetris clone. Vertris is written in C that uses the Allegro library for graphics. It is covered under the GNU General Public License (GPL).
Enhancements:
- A freezing bug was fixed.

Java Tetris project is a simple Tetris game.
Java Tetris is a game written with Eclipse and the VE Plugin. It is a nice starting point if you want to learn Java and Eclipse.
The game can be started as Java applet or Java application.
Enhancements:
- The dependency on jdom was removed.
- The jar is now only 30kb.
- A bug was fixed in the score list.

Ympyris project is a circular falling blocks game.

Ympyris is a falling blocks game that uses a circle instead of a rectangular grid.

Ympyris is a game that combines the idea of Tetris to the polar coordinate system. In normal Tetris-clones you move the falling blocks left and right. In Ympyris you rotate the well to find a place for the falling block.

This is a simple dockapp that monitors the following: the amount of users logged in, the total number of processes, the number of running (or alive) processes, the total number of forks and the system load average.
Installation:
make
su
make install
This will install the binary (wmmisc) in /usr/X11R6/bin.
Enhancements:
- src/dockapp_util.c: Properly get the user count.
- src/*.c: Clean-ups, removed unused/dead code, etc

CubeTest is a small program that allows you to train your spatial insight.
CubeTest is implemented with two different libraries, Trolltechs Qt library and the Java Swing library. The huge free software project KDE also uses the Qt library which means that this library is available on the majority of GNU/Linux systems.
The library is also freely available for Mac OS X. There are no other dependencies than either Qt or Java. There is no need for an OpenGL library despite the use of 3D objects.
For displaying the 3D objects Ive written a number of classes. A square in 3D is, when displayed without perspective, always visible as a trapezoid. Both the Qt and Java libraries allow a square to be sheared to a trapezoid. So with the right amount of shearing, a collection of squares looks like a 3D object.
The classes I wrote use this principle. Its fairly easy to make other 3D objects with these classes and use them as widgets. You can draw on the surface of the cubes as you would on a normal widget. In contrast with OpenGL, the scaling is done smoothly in the Qt classes. Its for example not hard to make a cube with sides that act as buttons as a replacement for boring 2D buttons.
The classes needed for makeing 3D objects are Object and Side. An object consists of an arbitrary number of Sides. Its also a Qt widget that can be manipulated with the mouse. In the downloadable package, theres a small demonstration program called fun which demonstrates the flexibility of the classes Object and Side.
Enhancements:
- Ported to Qt 4
- Two new languages: Italian and Portugese
- Cleanup autotools files
