erm absolutely not 15 million games of petrified were played lol. i think those numbers store a conglomeration of all variants in totality.
so you are saying that's the number of plays ALL variants have gotten?
welp also with such a bug community of chess.com is weird only 15 million games with ALL variants...
it's weird petrified is not on the popular variants list. Look at how many games have been played in a few weeks of it:
in the top you can see more than 15 million games played in few weeks!!
while other variants like XXL chess which are more interesting get the same plays! ??¿¿
