Hiashatar is a medieval chess variant played in Mongolia. The game is played on a 10 x 10 board. The pieces are the same as in chess with the exception that there is an additional piece which is called the "bodyguard". The game is not as popular as western chess or Shatar.
- King (noyon) - moves like the King in chess
- Queen (bers) - moves like the Queen in chess
- Bodyguard (hia) - moves like a Queen, but can only move one or two squares. The Bodyguard has a special power; any piece sliding must stop its move if it moves through any square a king's move away from the bodyguard. Any piece a king's move away from the bodyguard can only move one square. The only piece immune to this power of the Bodyguard is the Knight.
- Rook (tereg) - moves like the rook in chess
- Knight (mori) - moves like the Knight in chess
- Bishop (teme) - moves like the Bishop in chess
- Pawn (fu) - moves like the pawn in chess except that it can make an initial triple step.
- There is no castling
- Pawns promote only to queen
