Skipwalking
From Worms Knowledge Base
Early on, players discovered that if you rhythmically click the right mouse button while your Worm is walking, it can walk faster. Some people consider this to be cheating. Others feel that it is a legitimate skill, and a way to reduce the monotony of long walks. It is, however, generally agreed upon that skipwalking should be disallowed in Battle Races.

How skipwalking works
The worm walking physics is rather complex. There are two basic phases to walking; an "expanding" phase and a "contracting" phase. During the latter phase, very little forward motion is acheived.
This can be exploited. Right-clicking causes the game to open the weapons panel. The panel immediately closes because of the arrow key being held down, but the upshot is that input is ignored for one frame (1/50 second). This causes the phase of the walk to be reset, and the slower "contracting" phase is skipped.
Practical aspects of skipwalking
The rate at which the right mouse button is clicked makes a big difference. Click too fast or too slowly, and the worm will actually advance more slowly. At best, skipwalking provides a 1.43× speed boost; jumping forward is a faster way to travel when the terrain allows it.
Because of the way skipwalking works, it would be theoretically possible to do so by holding an arrow key for 1/10 second, releasing it for 1/50 second, then pressing it again, etc. This would be useful, because right-clicking has no effect during a retreat. It is virtually impossible to do in practice; however, by holding one arrow key and tapping the opposite, a skipwalk can be acheived during retreat time (because in W:A, opposite arrow keys cancel each other out).

| Download · Info |
Like with skipwalking, to "flipwalk" one needs to press certain keys at certain intervals to increase the walk speed. Flipwalking is somewhat faster than skipwalking (see "Speed comparison" above). It is done by walking backwards every 10th frame (9 frames of walking in one direction, 1 frame of walking in the other).
Flipwalking was discovered when the program BRSolver started using it to travel across flat surfaces after it was programmed to take into account all subtleties of the game's walking logic.
