Badshah ka wazir kon

This is a multiplayer game in which each game is based on 4 players. Each game has multiple rounds. In each round all players are presented 4 boxes out of which each player has to pick up a box. Each box has a value associated with it. Depending on the value of box the player is given some points. First two players with higher points are revealed. Those two players are Badshah and Wazir. Now the wazir is supposed to guess what other two players' values are. If guessed correct the points of all four players are set according to their boxes but if wrong the wazir's points will be swapped with the points of sipahi and sipahi's points will be swapped with chor. The Badshah's points will remain the same in either case. Which is why all players would be trying to pick the box with the value of Badshah.
