While not understanding the logic behind that I will definitely be there on Wednesday and will try my luck.
Well, on Wednesday you need to roll 7 numbers in a row instead of 8.
I didn't know about this. Thanks! Now I definitely should be there on Wednesday. Rolling 7 of those numbers in a row instead of 8 is million times easier, if I'm not mistaken. Here's my best result so far:

I will give you 10% of the Jackpot in case I hit it.
What do you mean in case you hit it? Of course you will hit it.
Just kidding, you don't have to give me anything

Well, it wasn't absolutely unselfish promise tbh. I think if you had a share in my win this would be advantageous for me too because the gods helping you would be helping me also.

So, whether you want it or not I'm determined to give you the 10%, and, as I said, it is not out of generosity.
