In the FAQ, you outline when the timer for the jackpot changes, but you start off with "100 BTC". Do you mean to say "100 BTC and lower", or is there no change between "0 BTC - 200 BTC"?
How many days on average do you expect each game to take?
There is no change between 0 BTC - 100 BTC, as soon as we reach 100 BTC it will be changed. That said I will be making some changes next round (not this round, to be fair with whoever invested I do not change the rules in a round).
The changes will be that the timer will decrease possibly on a daily basis and cost of participating will be adjusted up so that it will be more costly to do "jackpot hunting". That will help push people out and reduce the odds slightly. Right now it cost you 0.01 btc to try and win 33 bitcoins. That won't keep the game going fast enough.
As for how long this round will last I have no idea, but on avarage with the new rules implemented I imagine maybe 3-4 days on avarage.
