I never got more than 10% tokens back for several tries season after season. Who is the one who bidded a lot and got 80% tokens back?! Envy you!
I got 80% back from the first purchase and never participated in it again. Because it is a deception for those who do not know the theory of probability. For every 10 bets of 10 tokens, you get 23 back, not 80.
If the game "decided" that you will lose, you will lose.
