i dont have achivments that i should have

Who can fix it?

There' are some broken achievements

I will try to find a admin

"Participant" would mean getting 100 social points, forum posts give 1, blogs give 2 and club announcements give 5.

"Like! and "Tweet" don't actually require you to share a game you can just go to any page with their icons and press them.

If you still haven't received them after doing the above them you should contact support

Theres some tho that i got and disappered

They removed all the variants achivements except for bughouse and they also removed "hindsight 50/50", "second opinion" and many more

Wheres the varant bughoouse

Where the bughouse varant and other varant on android

There aren't any variants on the mobile app

However you can go to chess.com via your browser and press play > 4 player and variants > bughouse

I only have android
