What do G2, G5, and G10 mean??????? in challenges?

the "G" stands for "Game" - as in, Game in 2 minutes, G2, Game in ten minutes, G10.
 
that means that if you have made 30, 50, 90 moves, it does not matter, you cannot accumalate any more minutes and unless you mate your opponent, (or the other way around) when you run out of time, you lose. It does not matter how badly you are beating him - material-wise, the clock is your deadly enemy.
 
Caissa will declare a game a draw if neither player has materail enough to win, regardless of the time left for either side.
 
in short, it's for very fast people that need instant gratification.
 
Good luck!
