What I may change soon is how the most difficult game is determined. I'm thinking about changing it to the longest running game instead of the one with the most wrong answers. That way when users risk getting an answer wrong on a game that no one wants to play they can receive extra BRAIN.

What do you guys think?

If you like the idea, how much should the bonus be?

The only problem I can foresee with this is that an easy puzzle could stay up for a long time if everyone is sleeping. And then the first person that starts playing again could win the bonus quite easily. This issue would fix itself though once there are more people playing in different time zones.
