why do some online casinos have loyalty programs that are worthless

so i keep running into these loyalty programs at some sites where the rewards just don’t make sense. like you’d need to grind forever just to get enough points for a five dollar bonus or a couple spins. some even have these tier systems where even after a ton of play, the “benefits” are barely better than nothing. it almost feels like they put them there so they can just say they have a program at all, not to actually keep players coming back.

from a game design side, it’s weird - if the rewards aren’t worth chasing, people just ignore the whole feature. i’m always looking at how much you’d need to bet to get anything back, and it’s wild how bad the math is sometimes. is there something behind the scenes that i’m missing, or do they just count on players not checking how bad the value is? anyone ever actually benefited from one of these “loyalty” systems?
