The Kakashi line seems odd to me. The other lines are fairly normal for RNG winnings. But, Kakashi, the "prize", of this seemed to have its drop rate reduced after you won him 35 times. If this were just 100 spins, then I would say it was just an anomaly. But with this number of spins, seems to me that Oasis is limiting how many of the highest coupon price items you can win. None of the other items show this kind of statistical randomness.
