There is a version for ELO for multiplayer games: http://elo.divergentinformatics.com/

If this is not good enough, then I am pretty sure we can't do much better than TrueSkill. By the way, TrueSkill code can be downloaded here: https://github.com/moserware/Skills

We can also use TopCoder's rating system: http://www.topcoder.com/wiki/display/tc ... ing+System

Each player is assigned two values: rating and volatility. Volatility measures how quickly your rating my change. The system has been around for 10 years, works really well and is designed specifically for multi-player outcomes.
