Tack “&udm=14” on to the end of a normal search, and you’ll be booted into the clean 10 blue links interface. While Google might not let you set this as a default, if you have a way to automatically edit the Google search URL, you can create your own defaults.
For me it’s worse than Google. About half the time I have to run the search again in Google because none of the DDG links are relevant to my query.
