ad 1) Payment that is unconfirmed at the end of the round is returned to sender.
ad 2) Currently the jackpot is funded by us but in future it will depend on fees from previous rounds.

We always use the first address, is it ok? I think most games do it this way ...

Thank you all very much for playing in this round and for your patience - we are still in beta, payments are semi-automated ;-)
All payments have been sent recently - some of you receive it from the address of the blue fish, but some of you from other address (1BkD4SrL4RzwqT1zbfzzZE4SDoNJT8Z1kt), sorry... we are still fine-tuning the process.

I am very sorry, I will be back in 2 hours and answer all your questions. Thanks.

Sure... It's still in beta (but don't worry about your investment ). Thanks.

Yes, I am.
Thanks.
Currently we are testing a few alternatives - fixed fee vs. floating fee (starting at 0 % and raising to 100 %), how to deal with jackpot, etc.

Win bitcoins by investing into the fish you believe will grow bigger by the end of the round. The more BTC the fish receives the bigger it will grow.
