Robert, They have had slots for a few of years. The BJ and Rou. just this last year some time. Not sure the date. The Caliente casino is at the old casino next to the closed race track and current dog track, it is where the original Agua Caliente 1928 resort was, I should have taken a picture, will do next time I go, when I get my confidence up, with my friend who lives in San Diego, he said go when busy Fri. or Sat night, when more than table open, he also speaks spanish. We park on US side of border,walk into Mexice, taxi to casino, then taxi back to border, but walking into the US can take 2-3 hrs.
