Hi to all,
I am a student from Germany and have discovered bitcoins some days ago. To get a better understanding
of this whole thing i have written a small gambling game which can be played at:

http://zerocounts.dyndns.org/

You send bitcoins to an address and, depending on your transaction id, you win or lose. If your transaction id contains more then 3 zeros you win some btc. Due to the fact that i am not sure if it works the limit is currently 0.02 BTC but will be increased in the future.

Now lets come to my questions:
- Since the game depends on the transaction id the main question is: is it random, or nearly random?

- To get the probabilities i generated about 1000000 sha256 hashes from random numbers and analyzed them, is there a better way to determine the probability of a zero?

- Is there a problem when i publish links to the last  transactions? You can always get a new address for each transaction if you like.

Answers appreciated :-)
