The Quality of Game rankings that you see below are based on games that you can expect to find during peak times. The letter grades are based on a bell curve (creating more 'C' grades). If a game is rated as an 'A' it means that particular limit has some of the best games available for that limit (easy to beat, large pots). Conversely, if a limit is rated as an F it means that the games there are usually very poor (very tight, small pots).
