[P50POT] a multi-player mathematical game, played with bitcoin

[pfifty]

what happens when you send from more addresses?

Nothing special, use as many address as you'd like. Just keep in mind that prizes are sent back to the address which originated the deposit, so always use an address you control yourself (no web wallets).

i mean when you send from more addresses in 1 tx id
i mean address A and B send 0.001 btc to address C in 1 transaction for example
this is what sometimes happens when you have more wallets and use for example blockchain.info

Assuming address C in your example is the rounds target address, the prize (or refund) will be sent to either A or B, whichever is the first one in the transaction's inputs.

So, If you bet a large amount, you are more likely to win than if you bet a small amount. Have I understood it correctly?
It's not easy for me to get the way of playing

It is very open ended. If you deposit a large amount AND you're the only one doing so, then yes, this might increase your chance of winning. However, if another person is doing the same thing... then you lose your edge. A small deposit can then land between the two big ones, and win a hefty sum.

There's always some amount of luck involved, no matter how smart you get. And there is always benefit in strategic thinking, no matter how lucky your opponents are

I understand...

So, the round ends when the next block is mined?

is there any maximum bet limit? because if I go and bet 10 bitcoins or 100 then I will probably win...

[Mist]

I will go ahead and try this out, fairly new concept

[pfifty]

So, the round ends when the next block is mined?

is there any maximum bet limit? because if I go and bet 10 bitcoins or 100 then I will probably win...

Exactly, round ends when the next block was mined.

A single deposit is limited by 100mBTC, exactly for the the very reason you specified. A larger deposit will be automatically refunded.

So,what happens if two people bets 100mbtc? it's a draw? who wins?

Both wins, each collects half the pot. See https://p50pot.com/round.html?r=351176 for example.

Thank you so much! I understand it know, I may try it if I feel I can win

nice match(didn't win) I did what I could,but tournament said the first prize was 10,what does that mean in bitcoin?

All amount are in bitcoin. Which round did you participate in? Was is #351182 by any chance?

Fun idea, but most importantly great execution! Bravo.

With a quick script, it's it's extremely easy to "aim" your bet by creating and discarding hundreds of thousands of transactions, so that's going to make it pretty difficult for regular players using a normal wallet who will just scatter fire. And correct me if I'm wrong, but lets say I want to "aim" between txid A and B, I am better off not picking any random hash that happens to fall between them, but instead generate a huge set of them, and pick one that lies extremely close to either A or B. That is, so it would be extremely computationally difficult for someone to intersect my bet and A and B. Which would mean, with optimal software the game would favor people who can generate a large amount of tx's/second.

Anyway, love what you've done. Glad to see some fresh thinking on the scene =)

Wow, thanks you so much for the complement!

Your close-to-A idea is interesting, I must confess I did not think of that, but still, an opponent could just as easily send a couple of transactions to shift the balance away from that previous center. Spending all that computing time does not necessarily gives a real advantage.

[Rmcdermott927]

Very cool concept.

[RHavar]

Spending all that computing time does not necessarily gives a real advantage.

Wouldn't the dominant strategy be along the lines of "Look at all the transactions you think will make it in, then create a txid that will land you on the median"? But the more iterations you do of that, the harder and harder it becomes to bisect that range. Even after only a small amount of iterations, it could become extremely computationally expensive to find a txid near the median, and then trying to move that mass to change the median could be rather expensive and suboptimal

Since deposit size is capped, any two additional maximal deposits (both on the same side of the current median) are guaranteed to move it.

how do you do that?

This looks like the largest win to date, congratulation leen93 

[pfifty]

I have read the rules, but looks like players could cheating easily by send more bitcoin so his old transaction could in the middle & become the winner
Anyway, i have try with 0.004BTC

I hope i'll win

Thank you for trying my service out  

You can participate as many times as you want, even using the same address. Your 4mBTC did not win, but the round is still in progress- you should send more transactions if you want to win.

I am not sure I understand your claim that players can cheat. Since all participants are governed by the same set of rules, and anyone is allowed to send multiple transactions, no one gets an unfair advantage, and hence there can't be any cheating in the usual sense of the word.
