Looks like both Lottery and eSports are adopting Blockchain tech for their gaming needs, faster and easier than products like Poker, slots, etc.
Since these two are so different, they are adopting in different ways, but in both the customer have better transparency.
Anything that includes betting and gambling might just adopt blockchain. I have seen casinos with the lottery on it but never have I tried playing it. I'm not sure if anyone is really into it than a simple dice game to kill time. Lottery offers huge amounts to win but it's still not attractive to me when I can just play dice, no need of waiting, and instantly after a second or 2 I already knew the result.
