How does it work?

You decide how many "tickets" you want

Each ethereum cent is a ticket, so the more you bid the highest your chance. (Feel free to change the price of your tickets)

If you win you pay the price of all your tickets, if you lose you don't pay anything.

3 people take tickets
Alan takes 1 ticket, Beatrice takes 2 tickets, Carla takes 7 tickets
we make the total, here it is 10
the first person has number 1 , the second numbers 2 and 3, and the third numbers 4-10
We then draw a number between 1 and 10.
Let's say the random number generator draw the number "3", Beatrice wins and has a private listing at the cost of 2 tickets.
