  Summarizing the [Wikipedia article](https://en.wikipedia.org/wiki/Chaturanga#Rules), but comparing the differences between regular chess (that seems the most useful to me here):
  
  * Kings don't face each other, the black King starts on d8 and the 'Queen' on e8. Moving is the same, but castling does not exist.
  * The Queen (Mantri/Senapati) moves one step diagonally in any direction.
  * Bishops move like the Alfil in Arabic chess or some other variation (see the article, but unlike our current bishop).
  * The pawns (Padàti/Bhata/Sainik) don't have a double step on the first move (and hence no en-passant).
  
  Further different rules:
  
  > Al-Adli mentions two further rules:
  >
  > * Stalemate was a win for a stalemated player. This rule appeared again in some medieval chess variants in England c. 1600. According to some sources, there was no stalemate, as the king is forced to move and consequently be captured.
  > * The player that is first to bare the opponent's king (i.e. capture all enemy pieces except the king) wins. In shatranj this is also a win, but only if the opponent cannot bare the player's king on his next turn.
