And player choose which block to choose for rnd-generating. So player can manipulate prng outcome. That is not smart contract, that is piece of shit.

That's a prevenstion mesure if someone tries to send a gasfee higher than the bot has, it will make them calculate the winner but thats not how it regulary procedes, that just to avoid users to bet after the block hash is public. The funtion is called my the bot at the 14th block after atleast 2 players are in, this way it will be confirmed at 15th (or try to). under this sircunstances how can the outcome be predicted?

Your bot looks at block hash of last block. Then calculates winner according to code

Code:

function endLottery() internal {
        uint sum = 0;
        uint winningNumber = uint(block.blockhash(block.number - 1)) % totalBets;

        for (uint i = 0; i < nbUsers; i++) {
            sum += users[i].amount;

            if (sum >= winningNumber) {
                // destroy this contract and send the balance to users[i]
                withrawWin(users[i].addPlayer,winningNumber);
                return;
            }
        }
    }

If winner suits you, you will send transaction. If not, your bot wait next block.

again as stated, if for some reason the bot don't call the function, after the 15th block that can be called by any player that send a transaction with enough gas.

Okay. If you are so confident in your code, i shall create almost same contract. And you will play against me. Ok?

We can redeply the contract with that funtion in public, anyway the bot will call it as soon as possible so it would make users spend unnecessary gas.

You did not answer.

We will build change that in the contract, instead of being calculated the winner the block it is called, it will calculate it from the 15th block after it start rolling (the last block users can bet) and block the contract untill the funtion to roll a winner it's called.
I belive in that way we will surpasse that flaw.

You did not answer again.
