2. Instead of a board display, I get the message "Broken canvas...". What's up?
Well, it seems you're using a very old browser that doesn't support HTML5. Please use one that does.
Also make sure you enable JavaScript.

3. IE9: the game boards are not shown completely - the height seems restricted.
When you use Internet Explorer 9, please make sure you turn on "compatibilty mode" for the MindSports site. That should fix it.

4. I've made a wrong move - can I correct it?
Sure you can. On the page of the game you'd like to correct, choose "Undo last move" from the pop-up menu ("choose ..."). Enter your password and click the "Submit" button. Your last move will be rolled back after which you can enter the correct move in the usual way.
This only works, of course, when it's your opponent's turn. If they have already played, they have to take back their last move before you can.
If you work together you can even step back a number of moves (multiple undo).

5. My email address has changed - how to change it in my Arena registration?

  • Go to the MindSports Player Sections page
  • enter your (old) email address in the middle of the page
  • hit the "Preferences" button
  • On the next page you can change all your personal preferences, including your email address.
  • After you've saved your preferences - click the button at the bottom of the page and don't forget your password - the new address will be in effect immediately

6. How do I make a move in my game?
In short: click the piece you want to move, than click the target position. Possible targets will be indicated in the app. (some games require a sequence of clicks)
The app will only allow legal moves to be made. See the respective rules pages - click on the game's page title - to learn what a legal move is.
Finally, hit the "Submit" button to send your move to our server. This button will be disabled if your move isn't complete.
Make sure you enter your password if that entry-field is present.
