Improve many ifs that returns enumeration with Design Patterns

Of course, when we talk about number of ifs, we try to use the Strategy Pattern. But how about when I want to separate the conditions inside if().

For example, I am developing a game with many possibilites:

I have a class called Game. I check the method and return an enumeration.

if(TieByPoints()) {
  return Result.TieByPoints;
}
if(TieByTimeOver()) {
  return Result.TieByTimeOver;
}
if(JustOnePlayerWin()) {
  return Result.PlayerWin;
}
if(ManyPlayersWin()) {
  return Result.PlayerWin;
}

But many other possibilites/rules can be created. So, is there a way to separate in different classes? Put these conditions in different places?
