The S means "spacebar" which controls the two separate blocks when the large block splits.
In solutions, S stands for spacebar, which lets you select one half of a split Block to move.
Press the spacebar. This is indicated by (space) or by "S" in the solutions.
Bloxorz uses the 4 "arrow" (directional keys), to move Right, Left, Up, or Down, and the spacebar (indicated by an S in solutions) to toggle halves of the block.
There are many YouTube solutions under "Bloxorz level (whatever)" but there is a site with all of them at the related link below.
Press the spacebar (indicated by S in the solutions) to toggle between the cubes. When they meet, they immediately merge again.
The letter S in solutions means "spacebar" which switches control between the two halves (cubes) of the block when it is split. D of course means down.
S in a solution means "spacebar" which is how you switch control of the two halves (cubes). This is in the instructions. (see related question)
The solution codes show the directional keys (or spacebar when Block is split). R = right button (number of times) L = left button U = Up button D = Down button S = spacebar (toggles halves that move separately)
When you play Bloxorz you will see passcodes that let you skip to that level if you want to play it again to improve your score.
The S in the solution codes is the spacebar, not the S key.
No, Bloxorz is a computer game.
