How to remove restriction of account.

Do you mean play->play online->Custum game->open challenges?

Yes.

Or just Custom Game, and create a game by clicking the settings that are presented to you and wait for someone to join the party.

What settings, the thing that looks like a gear? I click on that and I do not see any relevant option there.

No, I mean when you click on Custom Game then you can click a few buttons, some of which have numbers on them which are time controls. You can click a slider to determine whether the game is rated or unrated. All of these should be very convenient. If they're not, maybe you want to switch your language to the one you're most familiar with. You can do so by selecting the profile settings through Settings and pick a language.

Just to let you know, 99% of players know how to do all of what's been said.

The things you mention in your last post are obvious to handle. But I do not know how to play games to un-restrict my account.

By just playing the games you're still allowed to play. The whole point of the restriction was to restrict some of your abilities. If you show elsewhere that you're a good sport, the restriction will be removed over time.

I guess another option is to just wait until the restriction is gone but a mod will have to confirm for me if this works.

I believe it's based on the rate/percentage and if you don't play more games, the percentages don't go down.it may also include a time element, so if you wait long enough, that may do it, but if it has that time element, it's likely over 90 days.

That's what I am saying, It doesn't let me play any games. The error message says that I can create my own challenge, and another error message was saying "you can play games with the poor group", but I do not know how to do these.

Just play some more games and the restrictions will be removed.

You should be able to just start a game:

I have done many aborts and thus my account is restricted. To un-restrict my account some error messages say to play with friends, and/or to create my own challenges, and/or to play with the poor group. What buttons do I have to press and with what order to do the 2 latter things? And when I try to play with friends it gives me an error message saying that I have a great rating difference with this friend and to try to play with someone with a similar rating as mine, but the rating difference is not so great.
