why some casinos offer bonuses that expire same day

Lately I’ve noticed a bunch of sites throwing up these same day bonus offers, like you have to use your free spins or match bonus before midnight or it’s gone. Feels way stingier than the week-long deals, but maybe there’s some angle I’m not getting? Maybe it pushes people to rush their play and risk more? I get wanting to limit bonus hunters but these are almost too tight.

Sometimes I wonder if it’s just another trend to attract super casuals who log in and play impulsively, instead of people who plan their sessions or track bonuses long-term. I usually just skip these unless they actually align with a bet I was going to make anyway. Anyone here actually take advantage of the short expiry ones, or is it just a trap for most?
