Paying members have an advantage of using various dynamic functions, accessing additional data or information which would not normally fit to the page structure.
One of the most important features of this type is a pulldown list of games to play, activated when a mouse cursor is moved to the red number next to Main page link at the left menu column. This action instantly shows a list of the player's started games, so the player can easily choose the preferred game to play, no matter which BrainKing page he is currently viewing.
The same feature works at the list of online friends at the right column - it shows a list of the player's games started with the particular friend. It is very useful when the player prefers to play games with friends first, without looking for them at the full list of all started games.
