casino says covering 24 numbers with bonus is low risk play, but it still loses plenty.

Casinos like to hype up "covering 24 numbers" in roulette, throwing in a bonus for a couple of straight-up numbers, acting like it’s a safe move. I’ve tried this setup quite a few times and yeah, you win something a good amount, but over a long session it gets chipped away pretty fast. One or two dry spins and all those chips are gone. Feels more like steady slow leaks than low risk.

Anyone else run the numbers on this or tracked their actual long-term results? I’m curious if the house edge changes much at all with these “low risk” combos.
