Happaned once yesterday and once today.

Yesterday I accepted, today I aborted.

Of course, they are not tournament games.

Anyone else?

I presume you mean your game with http://www.chess.com/echess/game.html?id=29535533 asar01? This hasn't happened to me, but perhaps it's a bug resulting from the game name changes a few days back.

Just happened again!

This game just started: http://www.chess.com/echess/game.html?id=29576390

Can anyone at chess.com take a look at it, please?

Yeah it also happened to me I didn't know why. I think you can't be in the Play Room if you're not playing.Because challenge will appear on Screen. Not good.oh well that's the way it is.

That's odd -- my first thought was that they would be tournament, team or maybe even greeter games but none of these appear to be the case.  Try reporting it as a bug:

are your opponents on your friends list? you might be set to accept friends games instantly.

 Yes, that was the first game.

 No, never saw them before.

 Thanks, I already opened a ticked, and pointed to this forum.
