Would this be considered gambling? Is there even a chance that this could or would work here on the forums?
Yes this is definitely gambling because you put in 10$ and have a 1/100 chance of winning, like any lottery. I think this is a good idea for this forum. There are many trusted users here who would easily function as escrow and another for lottery management. Some part of the winning would need to be used as fees for the two.
The only problem I would assume would be choosing which numbers to pick. Easiest would be if you assign the 100 participants a random number but I bet people would prefer to choose their own numbers. But then most people would try to pick their lucky numbers like 3,6, 13, or 19. It could be hard to fill all 100 numbers.
I do not need escrow (I provide escrow on these forums) I also do not need someone to manage it (I will) and there is no fee for myself - the goal is to raise funds for a charity not myself.
I was thinking to let people pick their own numbers - I do see your point in that some may not participate if they do not get their number - so that would be an issue as well if the numbers were randomly assigned as well.
Yes, this is among the many forms of gambling. I was wondering if this plan of yours is going to be conducted in different site if not, how will be the process of participation? And you have mentioned that this for a charity? What specific charity is it?
