Elo Rating Algorithm is widely used rating algorithm that is used to rank players in many competitive games. Players with higher ELO rating have a higher probability of winning a game than a player with lower ELO rating. After each game, ELO rating of players is updated. If a player with higher ELO rating wins, only a few points are transferred from the lower rated player. However if lower rated player wins, then transferred points from a higher rated player are far greater.
The algorithm is in app.js.
