roulette table min went up right after i started chasing losses with bonus balance

so this has happened to me a couple times now, the min bet at the table is steady for hours, then as soon as i lose like three spins in a row and try to go bigger with the bonus cash, suddenly the minimums jump up by a lot. i thought it was just bad timing but now i’m getting paranoid it’s not a coincidence. i know the site says they can adjust limits but it always seems to land right when i’m down and want to climb out. makes chasing way riskier since i can’t play small and ride out a cold streak anymore.

i play blackjack more than roulette but honestly never seen this on live dealer. only on the automated or video tables. is this just how these roulette games operate or am i missing something? maybe they auto raise when lots of bets come in? would be good to hear if anyone else has had the same thing, cause it’s messing with how i approach these games now.
