Most probably, the score of some of the players is equal at the end of a game. In this case, from now on the gain will be divided between the winners.

Here is an example to illustrate the case:

You play with 4 and the total gain amounts are 3600 chips. The winners in the game are 3 players, and if they have the equal result, the prize will be divided and each of them will receive 1200 chips.
