We do not display ads simultaneously both to the left from and above the game area. Also, no ads should be displayed while you are playing a match.
If you see those extra ads, then they are injected by some malicious software.
Please try the following:
- Try different browsers: Chrome, Firefox and Internet Explorer/Edge.
- If you can see the extra ad in all of those browsers, then a malicious software (adware, malware, virus) must have been installed. Check Control Panel / Programs and Features if you can see some software recently installed in the list.
- If you can see the extra ad only in one of the browsers, then an extension must have been installed to that browser. Disable all browser extensions to see if it solves the issue. Then you can disable the extensions one-by-one to identify the malicious one.
