new and exciting gambling

Hi there

We were developing a lottery type of gambling which is guessing the Ethereum Block Number.
When We see ICOs running a gambling site, why do they disperse it even though it is possible to do everything on one site? We was asked the question to ourself.
Users do not have to join multiple sites, and if you join a single site, you can use all the games freely.
We was convinced that ICO investors would be able to return more revenue if they were to offer a comprehensive game at Coin-Bet.

So we are going to develop more diverse, new and exciting gambling.
This will be completely new concept Live gambling.
We will have not only conventional users vs house casino system but also new Live games of users vs users system.

The gambling lottery form we were originally developing :

The biggest problem of the existing lottery form is that the winning number is based on the block number of Bitcoin or Ethereum. Of course,
there are some places that do random number generation. But this also has the possibility of manipulation.
The manager can not know the black number in advance, but the manager can manipulate the program and take the first prize as if he pre-purchased the number.
We are trying to prevent this problem and make a lottery gambling absolutely unmanageable.
It's simple. We can disclose the purchase details of every lottery buyer.

Gamble of scissors rock (House Fee: 2%)
When two users are gathered, they decide to win by paper scissors rock.
It is also absolutely impossible to manipulate. Two users will gamble by collecting , scissors, and rock.

Gambling of ladder (House Fee: 2%)
Choose a 2-line or 5-line ladder game to determine the winner.
The number of lines of the ladder is created by the users.
It is also impossible for the administrator(manager) to manipulate because the number of lines of ladder depends on the users.

Texas Hold'em
Preferred gambling by country- Bingo, Mahjong, Go -stop
Sports betting, E-sports betting, etc.
Is there any more interesting game for users? I want you to let me know about it.

We want you to help us.
