250 Scratch cards and no Nurse Belka.
Emptied my credits, played with reward credits until it was reduced below 10.
250. No Belka Event card.
I will just enjoy the cards I have in my collection. That's it.
It took me 271 attempts to get the Belka SEC,
Net spend was about 160 credits (much cheaper than some secs - I gave up with the Kaisa Nord SEC at 400 credits (although I did win it later). Other SECs have been averaging around 250 credits to win (for me).
Some people did it in much less - that is how "luck" works.
I could have used a Joker Card but I have bugger all to spend my money on at the moment.
