Good news to see that now you have a better rates than before.
And I think it should be followed by some other promotions, something simple like higher faucet amount, deposit bonus, bonus code like what you've done before but without rollover requirements, bounties for rolling in special numbers etc.

And for your game, I hope there will be an option for player to decide his bet is "Lower than xx number" or "Higher than xx number". because for now, player is only able to bet for "Lower than xx number"
