But in this case DDG does give Google's auto-corrected (without even telling you!) and I bet it happens to many terms as it is mostly a proxy/filter of Bing.

Edit 2: Hey, that's weird. Adding a comma, semicolon, period, or other symbol to the beginning or end of the query makes the gamed results show up on top at thor and www as well. Seems to work for all the terms at issue:
There were a number of bugs around the first result that this whole thing uncovered, so it could have been intermittent. Our backfill in the case of no results can vary. It shouldn't have been showing anything ever beyond the first result though.
