Please help me to get Dangerous intersection achievement

hello I am also trying to get dangerous intersection achievement. i have played 4 player chess but it didnt unlock. help!!

Even i played around 2 games and won them refreshed my achievement tab but i still didnt get it!??! It doesnt even work for Crazyhouse or King Of The Hill

I have 12-13 games and 2 tickects...so no use...if they dont respond to some minor propblems...if you have real problems I dont expect much from admins
It's difficult. I haven't yet found how to handle. What do you think about Block Blast?

It is written that ten games can give you that. but dont go for variants->4PC, Go to play->4PC to get it
The question is in the title. Please help me as I have already played 3 games of four player chess but still didn't get the achievement.
