Only 1 lucky winner doesn't seem to be much nice. About 100 participants are required and fees seem 0.06 eth per person so it is a definite profit for yourself
No, it is not.. From the moment of game start, Every prize pool is started with the 1 eth I have deposited. My break-even point is 33 players per round.
When the number of participants exceeds 33 people. Will all of your donation go to you? Every idea comes to a profit. But limit each round to 50 people, benefits are required but not all from players. Need some changes in the number of dark participants to make things fairer.
