On Replay Poker there are three stake levels that designate player rank: Low, Medium, and High. Currently these stake levels are tied solely to the amount of chips you have in your bank.
Everyone starts off at the Low stake level, which has the range of 0-74,999 chips. When your bank has 75,000 - 249,999 chips, you are in the Medium stake level. Then as you continue to be awesome and your bank has 250,000 chips or more, you are in the High stake level.
Your stake levels will continue to update as your bank balance goes up and down.
