I'm making this separate post to not mess with my answer to
@kaiji.
My result from this game in graphics and some explanations.
I started playing with 84 credits and I had to buy 250 then 500 credits to keep playing and get the special card.
I did not plan to buy that much and in fact I could have bought less, but ...
The average of the game win/loose isn't really bad 54% win against 46% lost for a total of 109 times played.
It took me 102 games to get the "Special Card" and the effective cost for it is 350 credits.
In total I spent 1090 credits and earned back 740.
Over these 109 games I won:
- Bonus 10 - 54 times
- Bonus 50 - 4 times
- Bonus 100 - 0 times
- Free Card - potentially 8 times but I've never had one since the only cards I do not have are the 6/7 new cards released this week and it looks like we can not win them in this game
- Event Card - 1 time
On the graphic 2 (top right) the "Saw" results are the number of times I saw that bonus during my 109 games (win or lost) and the "Won" are the effective times I won the bonus.
Considering those results I would have ended with 8 free cards + 1 Event Card for a cost of 350/9 = 38.88 credits per card and I'm ending with 1 Special Event card and 484 credits over 834.
