There’s no known lottery project here that has a mechanics like this which distribute prize on random user. It’s more on a raffle than a lottery since user is not betting on a picked numbers but rather the smart contract is just selecting entries as winner.

L0tt0.com is your nearest competitor for lotto based game. The only problem on this kind of game is every round can be useless whenever there’s no participants aside from one user who place bet compared to a regular lotto games which the casino provides prize pool for players to win with their bet. This game is more on just PVP.
