You click on your icon and a whole selection of options about your play comes up including ELO ratings. I wouldn't bother or worry about your ELO ratings as they are very corrupt if you are not paying for the games. If you are in for the free games you will lose often enough no matter how well you play. The dice roles will benefit those who pay and crush those who do not. Platinum level is the highest you can reach when you are playing for free.
