I have the same problem. Somewhere in the "help" listings it says that on my "Daily Chess" page, to the right of the current games, there is a box containing the word "Play" and under it a link to Open Seeks. I have a box with "Play", but under it is nothing but "Join a Tournament". I, too, had to abort a game because of attempts to find the Open Seeks. Can anyone help?
Open Seeks

On the website, Play > Daily Chess. Under New Game, change to a Daily time control and then choose the option Open Challenges
The app is similar. You go to Play, hit the + for a new game and select Open Challenges.

Thanks, Martin_Stahl -- it worked for me, too. I wonder if some programmers ever try using the programs they have created.
I can't seem to find the open seeks for, say, a 3 day game without accidently starting a game I don't want to playand having to abort it. I tried it 2 different ways, started 2 different kinds of games, aborted them and then got a message that I can't continue to abort games. Where can I find step by step instructions to find the open seeks without starting a game I don't want to play accidently?
