Got some free spins on LeoVegas and they actually paid something

so i got some of those random free spins they throw at you for slot promos, usually i write them off cause slots chew up my time and don’t give much back. but this time i spun through twenty spins on some ancient egypt thing and ended up with like 40 bucks, no lie. i know it’s not retire-early money but usually i’m lucky to get 2 bucks and some disappointment.

thinking about whether it’s smart to just cash that out or let it ride on some blackjack, which is my usual spot anyway. wonder if these little random slot freebies are worth chasing or if i just hit an outlier. anybody here actually stack up decent wins off these free spin deals or is it always gone before you blink?
