Can you invite specific players to play?

thanks for the message. I will consider it.

Recently, I am a little busy, and will work on this site after some time.

added invitation button which you can invite online available players and invitation linke button which you can copy a game link and send it to friends to invite.

Note that for players that have not login, they will be redirected to login page first. On Chrome browser, the link works fine. On Firefox, not-login user needs to login and manually revisit the link once; after the first login, either registered or guest account, the browser will remember the user, the link shall work fine.
