That's maybe because you have the "Block sites from setting any data" option checked instead of the Allow local data to be set option on your content settings. Check that on your cookies settings.

Also you're able to play on incognito mode because the incognito mode sets the "Keep local data only until you quit your browser" option by default, that makes possible to use cookies but it will delete them after you close it.
