Welcome to KLACK!. KLACK! is a game consisting of four spheres, a
rotating pointer, time and score counters and just one key per player. Read
more for details.

screen usage of the old version by using different files for different
By the way, since Jerry joined in we are planning a rewrite using SDL, so stay
Ok, let's start with a screenshot and then get to the rules one by
- Center of the game are the spheres. You can accelerate yours by
pressing your key.
The player keys are: Tab, Space, Keypad-Plus and Mouse
Whenever a sphere collides with another, points may be awarded or
removed from the player's score.
- You will notice the pointer in the lower right of the window. It shows
the direction of the actual acceleration.
- In the lower left, all player scores are shown.
- Right beneath the scoreboard, a timer is showing the seconds
left until the game ends.
- Between the timer and the direction pointer is a small diagram
showing the rules for awarding points. Everyone starts with zero
points and nobody can get less than zero points. In the diagram, a green
arrow means that a point is awarded, and a red arrow means a point is
removed. A black arrow means the points are carried over. By now, we
have two game modi:
- Shuffle: The original game. You control (more or less) the
green sphere, and try to let the yellow sphere hit the blue
sphere while avoiding the red sphere. Fair enough, hu?
- Cascade: This Four-Player-game is quite easy to explain:
Bump into your right neighbor, but don't get hit by the left.
Naturally, the leftmost player has to fear the rightmost.

Caution: Be warned that this version is unsupported now.
- Spheres may bump into or even through each other. I now have the
outlines of an improved algorithm that does vector clipping.
- After a cascade game only player 1's score is shown.
- The manpage is incomplete and needs translation.
