I'm starting to rewrite this in clearer English. I have this so far:

The board and piece setup are the same as in normal chess. But each player has two camps and can spin either one. Each camp is a 4x4 section of the board. White's camps are on the first four ranks, and Black's are on the last four. Each has a camp on files a through d and another on files e through h. Instead of making a regular move, a player may rotate the pieces in one camp 90 degrees clockwise or counterclockwise.

This covers everything up until this line:

The pawns only go to the last rank of enemy regardless of spin.

It's not clear to me how this works. An example where this rule applies may help to clarify it.

Regarding the last line:

The pawns are promoted when the opponent spin his camp and your pawn reaches at the last rank of enemy.

Who decides what pieces the pawns promote to? The player whose move placed them on the last rank, or the player who owns them?
