I had over 300 cards available in the store from 2019 and 2020 even excluding the previous 30 days ones. Why aren't any of these selected then?
Like all of the Events, not all of the win options will be to your liking,
in that case your option is to spin again, or to not play.
Randomness is just that, it's random...
5 spins, 40 spins, 100 spins is not enough to draw precise evaluation of the random odds.
the results of the spin are based on the NOT owned cards for that particular Member.
but it doesn't mean that ALL of the results will be as expected.
So if the spin results do not meet with your likings, then you can Spin again, or not.
I used to play roulette, quite a lot.
I spend a hours tracking the spin results to make my own Hot and Cold number list.
when I had Cold numbers than had not come up in 200 spins
I'd start to bet heavier on them, and double up every 5 spins
Because I thought,
It's been 300 spins and they have to come up..
Well 1000 spins later, and $100 lost,
the COLD numbers still had not come up.
but some of the HOT numbers must have came up 10 times.
randomness is random, and you can't predict it, or pattern it.
