I could be wrong, but I see 9 times where you've won the lottery just today, with the last one being at 8:21 AM. I think it shows up like this on Hive stats and sometimes, there's a delay before the tokens show up:

"operation.hive_engine.name.mining_lottery"

Again, I could be wrong, but I think those are for VIBES tokens. You can see it in your hivestats.
