This table lists players sorted by the return on investment (ROI) generated in public online DD Poker tournaments. The ROI is based on the total money spent (buy-ins + rebuys + addons) and the total prize money won in those tournaments.

An ROI is an interesting way to do rankings (rather than gross dollars earned) because it is impacted less by the size of the buy-in and rebuys (online play with DD Poker is not for real money so the actual buy-in amounts are arbitrary). One issue with this ranking is that it doesn't effectively average wins in big money tournaments versus low money tournaments. The DDR1 ranking is intended to handle that.
