The transformation of pieces are regulated by the additive reversible rules of the composition.

The move can be done not only by the whole compound piece but also by any part of it. A simple piece can be moved to a square occupied by another own piece, if the result is the formation of a correct compound piece. The quantity of pieces of one color on board can't be more than thirty.

Rules of the game:
1. The orthogonal mode of the movement O or O(n), where n is the number of the path cells.
2. The diagonal mode of the movement D or D(n), where n is the number of the path cells.

3. The neighbor mode of the movement N or N(n), where n=1,2,3 over the neighbor occupied or unoccupied squares (Jump).

4. The jumping mode JO or JD means that a piece can jump own way over one other (friendly or enemy) piece (hurdle).

1. The progressive (unclassical) pawn (P) moves ahead from third row by O(1) mode; from fourth, fifth rows without the capture by O(1) mode or with the capture by D(1) mode; from sixth, seventh rows by O(1) or by D(1) mode.
Pawn may advance in its first ahead move, without capturing, by O(2) mode.
The pawn may standard capture «en passant».
The pawn that reaches the eighth promotion row promotes for the spy.
The rule of third pawn. The achievement of the eighth promotional row by third pawn brings the victory.
2. The spy (S) moves by N(1) mode.
The spy that achieves ninth promotion row promotes for the wiseman.
3. The knight (N) moves by N(3) mode.
4. The guard (G) (pasha or mastodon) jumps by N(1) or N(2) modes.
5. The bishop (B) moves by D mode.
6. The cardinal (C) combines the powers of the bishop and the knight.
7. The rook (R) moves by O mode.
8. The marshall (M) combines the powers of the rook and the knight.
9. The adviser (A) moves by O or D modes.
10. The wiseman (W) moves by JO or JD modes.
11. The queen (Q) (Amazon) combines the powers of the adviser and the knight.
12. The king (K) moves by N(1) mode.
The achievement of the ninth row by the King brings the victory.
13. The emperor (E) combines the powers of the king and the knight. After check he loses the knight and is transformed to the king.
When (double) castling, the Marshall move towards the Emperor, the Rook move towards this Marshall and the Emperor moves to the square at the other side of this Rook (for whites: 0-0 (Md1, Rc1, Eb1), 0-0-0 (Mf1, Rg1, Eh1); for blacks: 0-0 (Mg10, Rh10, Ei10), 0-0-0 (Me10, Rd10, Ec10)).
Castling may only be done if the Emperor, the Marshall and the Rook have never moved, the squares between the Emperor and the Marshall involved are unoccupied, the Emperor is not in check, and the Emperor does not cross over or end on a square in which it would be in check.
The achievement of the ninth row by the Emperor brings the victory.
14. The (stale)mate brings the victory.
