I asked the same question at the past and i am pretty sure the right answer is not a hack or a bag.It is just a fixing of time due to different internet connections(lag)
Resolved: never ending secs
well I've just played with chess_photon and in a 5:00 min game he was able to get 5:01 so that's not an internet connection lag, when I confronted him he just wrote LOL and his time kept boosting up.
Hi I was playing wit gianfausto1 and when he had less than .7 secs the time started comming back and forth for about 10 more moves, from .7 moved to .4 and then started again at .7 does anyone know if this is a hack, a bug or what's happening??
