I did (A LOT of) both day game and night game back in the 2000s. No luck doing either obviously.
In my experience day game is worse. Most of my worst rejections were from doing day game. Women don't want to be approached by random men in general unless they're good looking, but they really don't want to be approached by ugly men, and they really don't want to be approached by random men when they're going about their business during the day (yeah yeah, Chad is the exception). With day game I usually went with malls, but I also tried coffee shops a lot because I heard somewhere it was a good place to do day game. But based on my experience, I can say coffee shops are the absolute worst place to approach women. I think I would have gotten less harsh rejections if I approached at a funeral or something.
Night game sucks too. Got a low of "EWWWW" rejections but not as bad as some of the rejections I got doing day game. At least at bars, clubs and house parties women expect guys to cold approach them as they're more social venues.
Overall, I don't recommend either, especially in 2026. But frankly I don't think they were ever a good way to meet women. Back in the day most couples met through friends or at places where you'd see the same people everyday, thus be able to establish rapport (eg. work, college). And now of course most couples just meet online, usually via dating apps. Cold approaching was always a PUA grift. The only reason I did so much cold approaching was I already got rejected by all of the single women in my social circle, and online dating wasn't working out either, and I felt like I had to do something otherwise life was just passing me by.
