Thoughts:

- Deposit was in my account 6 minutes after the 2nd confirmation

- I don't love that the bet on every block has to be the same.  I'd like it a lot more if you could vary your wagers per block.

- The animation to show which block wins is cool but it completely obfuscates my picks!  When the row is highlighted, I can't see what numbers in that row I bet on which makes the whole process kind of worthless.  There needs to be some sort of transparent overlay when the winning row is selected so that the players can see what numbers they can win on in that row.

- There were a couple of times where my "bet" and "clear" buttons didn't work for a round.

- Not really social or multiplayer.  There is a chat box, but even if it was active it wouldn't really add anything to the game.  "Oh are you betting on 3, I'm betting on 7" I mean that's not really adding to my experience you know.  The only time the other players would add anything to the game experience would be if the max bet number was close to being hit on any specific box, and even then all of the boxes pay the same and hit at the same frequency so that wouldn't be a big deal.

- System wouldn't let me withdraw my entire balance.  System wouldn't let me withdraw my entire balance minus miners fee.  System WOULD let me withdraw my entire balance minue .0002...and then took the miner's fee out of my withdrawn amount.  Seems like a bug.  If you are going to take the miner's fee out of the withdrawn amount (which is fine), you need to allow people to withdraw their entire balance.
Withdraw was processed instantly, which is good.

Overall it's an interesting concept but has some small issues affecting the player's enjoyment.  Personally, it seems like a more restricted dice game and I don't see me putting much more play in.
