Little update,
Some people asked me what it has different from Luckybit. I'd say mostly the loading speed.
People has reported that flappybit load faster than lucktbit and uses less cpu% on the page.
Also, when you get disconnected, the script auto reconnect you back when possible.
I'm currently looking at moneypot's api. Maybe it could be better for the users to be using moneypot?
This way, people won't have to wait for confirmations to bet.
If you have any questions... Don't hesitate

Luckybit is like the original SatoshiDice: an on-chain game waiting for an off-chain competitor to eat its lunch.
Use Moneypot to handle the Bitcoin interaction/bankroll/investment so that you can devote your time to polishing your casino.
Flappybit is a great start and you obviously have the tech skills to compete.
