Topic: Rock Paper Scissors -- First player vs player casino on Moneypot. (Read 931 times)

Yea, Gmaster figured out and told me about this. It was kind of an exploit. It should be fixed now

btw my balance was reduced by 18 bits even I did not wager but  I saw this searching circle for a very long time and after I canceled I saw my balance was as before and then when I wanted to withdraw it was 18 less

it looks like a bug to me. not that I want the bits back or any bug finder bonus just trying to help

this does not make sense to me as it is a pvp game

If someone is able to see how much the opponent wager or who he is, if this guy likes to play 'rock' then it could be easier to out play this person and make sure to get all his bet.

ok and what is a sniper or snipes? what advantage does he have when I put my bet amount in advance?

At the end of every matches, you can see : YOU WON: +
or YOU LOST: -

where do I see how much I won? I see stake 210

what is a sniper in a RPS game

The game is made so both players do not know who they are fighting against. This to avoid any 'snipes'.
The stake, is also to avoid telling who won how much against who. (if this makes sense) Helps keeping some privacy and also for the snipes.

The amount you win/lose are shown only to the players at the end of the matches.

I'm sure that snipers could kill this game quite quickly.

ok and I wagered 10 so this should be changed cause it should show 20 bits = each had a wager of 10 in real even you bet 200. it is very irritating  imo

and the suggestion I made before would be nice that each player can put in his wager in advance and see the opponents wager also

you are reading my mind and taking same and that means you love ties loll

Nice work, Dexon!


The problem with provably fair pvp games, is that they're extremely difficult to actually make provably fair. The way player-vs-house games provably fair works, is the house actually commits to a certain "move" before it could possibly know the players, and then is bound to make that move.


With RPS, the simplest provably fair would be:

Player A makes their move, tells the server the *hash* of their move (obfuscated with a nonce)
Player B makes their move, tells the server the *hash* of their move (obfuscated with a nonce)

Once the server has recorded the hash of both players moves, it then would send it to both players (So they can also check, making it provably fair). Once both players know their opponent hash, they send to the server their own move and nonce (for the server and other player to check).


The flow with this is quite straight forward, except it relies on one thing: If a player can't produce the move (and nonce) that leads the hash, they would need to be forfeited and lose. This might pose a problem with disconnections, and what not. There's a lot of edge cases, and to make it truly provably fair does require a lot of work, and unfortunately a reduced UX [1] due to the whole "lose on disconnection, or failure to produce the result" rule



[1] This could be reduced by having a "trust the server" tick box, which means the client trusts the server and immediately sends the move to the server, that way in the case of disconnect the server would be able to play the move in the persons absence.

I bet 200 bits fwiw.

edit; Stop picking paper!

please explain the following. how much did I win when stake shows 210 bits?


Winner            Loser              Stake
JackpotRacer   dogedigital          210 Bits

I would trust you or some others  I could name but there are many bad examples of MP app owners in the past and if they copy this game or any other pvp game that could end in a disaster

suggestion

I would like to put my wager in advance for pvp as in any case I can only lose or win what the opponent will bet against or if he puts more than me I cant lose more than I have put in

This is really true. And as it's just to test out the "pvp" theory on moneypot, this game might never get a high visit/play rate.

To run a successful player vs player game, u need to have multiple players on your site at the same time. This is difficult to achieve as u r just starting off. Player vs House make work better initially.

I mean, the server has an anti-cheat to avoid players to cheat the games.
But I could understand your concern here. As the op could see the others bets before he makes his own and steal. Unfortunately, I think the only way would be to trust the guy.
I can't think rn of a solution to that. I could always make the code open source as proof...

that I am not cheated by any player or app owner ( not saying that you will cheat )

What would a provably fair imply exactly in this case?

I think it is more fun to play vs a real player than the bot, it makes the games more challenging

does it matter if I fight the casino or in a casino another player? shouldnt this also be provably fair?

what do I miss here?
