Can anybody elaborate on the scores when there are 3 players ?
Does it not related to how close you were for winning ?
ELO does not consider how big the win was. It was designed for chess, where the score is always 1-0, 0-1, or 0.5-0.5. As such, it doesn't matter if the win in Can't Stop is 3-0, 3-1, or 3-2; it treats all of these as 1-0.
In a multiplayer game, ELO calculation is done as if several 2-player games were done. So if the final scores are A:3, B:2, C:2, D:1, the final ELO will be treated as if:
A defeats B, A defeats C, A defeats D
B loses to A, B ties C, B defeats D
C loses to A, C ties B, C defeats D
D loses to A, D loses to B, D loses to C.
The amount of points shifted in each matchup depend on what the initial ELO difference was. It is more likely a higher-ranked player will defeat a lower-ranked player, so there will be less of a points shift if it happens that way or if the lower-ranked player wins. Then, too, there is a factor based on how many games the player has played (to more quickly get a newer player's ranking closer to their accurate value).
Hovering over the ELO on the end screen will bring up a pop-up showing more detail on these calculations.
