A share of certain percentage of the web's profit, as you had planned and mentioned a few weeks ago.
I know that Isen had state something similar to this before me, but since he mention two possibility in one chance, I think it violate the rule, so basically I will help him decide by giving him the free dice credit while I take the profit shares, LOL.

If I may guess further, your plan is to give certain amount of "ticket" per claim and at the end of the period (either monthly or weekly or something around), each user receive some percentage from the amount of "ticket" he owned divided by the sum of ticket claimed by all users.
