Thoughts:

- Interesting concept but a little confusing to a new player.  The help/how to play page should be the first thing people see, not hidden under a 'help' button.

- 15 second timer between rounds is too quick.  Should be ~ a minute to allow everyone to clear their boards, bet new amounts, use -ev 'systems'.  Plus rapid fire rounds takes away from the social aspect.

- The ability to wager different amounts for different numbers would probably make you some money.  People want to use strategies...let them.  Also I would take away the "odds" under the total bet...people want to see "make 63x on your bet" not "make 2.2x on your bet".

Interesting concept, nice new take on the dice model.  Personally, I'd like it a little better if it was more pvp and less house-based (basically if there was a way for the winning number bettors to win some % of the losing bettor's bet).  There are def ways to do this that encourage social aspects of the game (like Moneypot's bonus structure), but I understand the desire to keep it as simple as possible.  Also I'd add that play money play probably isn't going to attract many people.
