well I just played several rounds to give the game a trial.
suggestions:
your site needs a FAQ for the players.
I'll add one.
each game should show its end time or do you just play until all tickets are sold ?
The game runs until all of the tickets are sold.
As for random number issues, (Im still a bit groggy from my recovery) but I dont see any exposed secrets ?
Not quite sure what you mean by an exposed secret, but im assuming a piece of data to confirm that the random number generated wasn't pre-selected?
I made several bets to get the games rolling for you.
Thank you.
