Elo ranking system

If you've not heard of the Elo ranking system before, it's probably worth a quick read of it's Wikipedia article. It will give you a much better understanding.

GamerVenue adaptation

The K-factor of a rank controls the scope of change between a win and a loss. In other words, it's how confident the system is that the final result is a fair representation of the players skill. The larger the K-factor the more results it will use to determine a rank where as a smaller K-factor will resist the urge to change a rank too soon.

Inflation

Occasionally players will enter the system, compete in a few games with experienced players and lose. They will then not play another game in a long time. Effectively, this dumps extra 'points' into the ranking system that are then gained by experienced players. The problem we have here is that experienced players will gain too much and it will be extremely hard for new players to catch up.

To counter act this inflation problem we use a much smaller, fixed K-factor for new players until they have competed in a minimum number of games. This simply limits the rate at which new players will lose points and prevents a large dump of points into the system until the player has gained experience.

Rank titles

Each player has a Rank title assigned to them. This title has absolutely no effect on the Elo system nor is it effected by a players position. Instead, rank titles are determined primarily on amount of games and the players win ratio.

  • Unranked 4 games or less
  • Rookie 5 games or more
  • Semi-Pro 10% Win ratio & 10 games or more
  • Pro 20% Win ratio & 20 games or more
  • Veteran 30% Win ratio & 30 games or more
  • Expert 40% Win ratio & 40 games or more
  • Master 50% Win ratio & 50 games or more
  • Legend 75% Win ratio & 75 games or more
  • God 90% Win ratio & 100 games or more
Rank titles subject to change over time after players reach specific benchmarks (e.g more then 50% of players have competed 100 times).
