The better odds, the more players will be attracted, that is logical. The question is how you can build the platforme and ensure the best for players and that everything is legitimate and trustworthy.
New platforms appear all the time but only few manage to attract and keep the players for a longer time.
The higher the odds, the lower the winning chance. So it is somehow balanced. You will either go for a bigger prize or a higher probability of winning. That's fair.
Also, the higher the winning chance, the more expensive the ticket I assume. So the players will be torn between just taking the chance and pay for a cheaper ticket or trying to really make some money and pay for a more expensive one.
single ticket but expensive price ? this is new to me . im only thinking of the traditional lottery with fix price tickets but the only way to increase the chance of winning is to buy more quantity of tickets with different numbers pick on it but this was online so introducing new twist is still welcome . just want to say goodluck to the op for venturing the world of gambling . gambling markets are pretty competitive but still few lotto games that i saw here , so you still have a chance to shine
