The chessboard is rectangular, 99 cells (9 horizontal cells, 11 vertical cells). The fifth cell in the second row in each side is fixed position of zero (0). It means during the game(match) zero can't move. The chess-man is natural numbers from 1 to 9. Initially numbers are set at the bottom row of each side. The order is ascending from left to right (1,2,3…7,8,9). The numbers in the same side is the same color. The numbers in different side is different color.

Vietnamese Numeric Chess is different with Chinese Chess and King Chess when eating chess-man of opponent. In Vietnamese Numeric Chess, it needs to be two 'numbers' with the same color stand in two adjacent cells to make one of four basic calculations: Plus (+), Subtract (-), Multiply (x), Divide (:). Whereas chess-man in King Chess and Chinese Chess can eat opponents directly (except for Cannons in Chinese Chess).

Finally, We hope that you can help us to translate this game into other languages in the world such as French, german, Italian, Japanese, Russian... for every people can play it.
