Hey cool, thanks for the chance to test this service (and the chance to win).
Because you stated I needed to send it from the exact address I received the 1 BTC on I made a new (empty) wallet to be able to make sure this would happen. However of course there is no money for the transfer fee so I transferred a Bitcent to the address to cover that and will be able to find out whether I win after that confirms.
So far I have taken a look at the site and it looks really smooth and user-friendly. I especially like the linking to third-party operators for buying the needed Bitcoins (widens your target audience I think). So far I have read the FAQ. I must say I had to read it a number of times (can be the time) before I got that the pools were the actual prize pools for regular play based on the number of matches. I initially thought it was a bad beat jackpot or something
Furthermore
* What is the exact house edge? (10% on losing bets, but what amount of bets wins)
* What are the minimum amounts for the different pools?
* Small mistake: "That tweet generates a tweet ID which you can see in this chart, the tweet ID is used as the key for making a new HMAC SHA-512 HASH of the first hash which finally, gets the last hash. " 'This chart' doesn't point to anything (I wanted to look up how Twitter generates the id).
* Free plays and high roller bonuses was explained well
* After the transaction and entering my address I could immediately see the bet was received but still needed to be confirmed
Edit: it confirmed while I was typing, it is currently playing
