Halloween weekend is here.

Have you found any particular online casino Halloween Promotion or Bonus worth checking amongst reputable brands?
I have seen some decent ones as well as some not even worth checking out.

Hi, Bitcointalk community,

One of the crypto casinos is organizing a prize draw, with the one/top prize worth €52,000. Rules are pretty simple: For every 100 EUR wagered, the player gets one raffle ticket. Of course, the more tickets collected,  the better your chances of winning the top prize. It’s a classic lottery-style draw, motivating the players to wager high to collect more tickets for a better chance of winning this event.

The problem is that neither it’s a live event nor a provably fair event. Therefore, some of the players might question its fairness.
In your opinion, what would be the best solution to integrate a quickly provably fair option?
