Earning Cubits in an unrated game?

I want to play unrated game because I don't want to lose rating.But at the same time I want to earn cubits.My question is that: How can I play an unrated game for cubits?

Unrated games are not used to play wager games as player of high rating can play at a lower rating and win cubits without getting rating changed.
If you dont want to loose cubits playing unrated games,please buy memebership which gives unlimited free games.

Also you can enter unrated tourney which are free to enter and can win prizes.
