Slight problem. You can cheat by viewing the blockchain:
https://blockchain.info/address/18j3TfeSf4MLQsukw7kHiFKj3xhTqfrAD9Click on the most address sending to that address and you can see how much the person before you sent.
This will resolve itself if people are depositing as frequently as say 1 deposit per 10 seconds. If that doesn't happen then I suggest using a different method.
Hey! I'm actually really glad you posted this! ^.^
I noticed that within 5 minutes of release!
I have since remedied the issue by doing this:
1. retired the original address so its no longer being used ;P
2. set my transactions to be sent through a shared wallet so they are way harder to trace
3. created about 50 something new random addresses
from now all btc will go to one of these random address then be sent back via a shared send!
so its going to practically impossible to try and cheat by finding my addresses now!
plus it will only get harder the more people are playing at one time!
-Have a nice day :]
cool game, but would be better if a trusted 3rd party/escrow service was used to store the deposits..
