[ETH] Play Rock Paper Scissors - Featured on ether.camp blog !

A more fair function would be to have only one function to reveal, testing the 3 sha3 hand hash comparison and finding out. It would then make the other player to ignore the first reveal, so nobody know yet who wins.

Then, it would allow the players to bet and leave, free to play or not, and if they do not play after 2 hours, both players are refunded, and nobody knows who would have won.

What do you think

It is indeed possible to use a single function to reveal that would cost a bit more gas tho. It would keep the move more hidden in the sense that you would not know which function the player used. But you could still see on the EVM (ex on live.ether.camp) what was the move of the player since you have to store the true move somewhere once revealed.

But anyways, I don't understand the next part of your message. You said : ""Then, it would allow the players to bet and leave, free to play or not, and if they do not play after 2 hours, both players are refunded, and nobody knows who would have won.""

Why would it allow more to bet and leave than in the current game ? Right know you can bet and immediatly reveal once your are matched.

I wasn't clear, forgive me

I meant, that, right now, you force people to reveal in less than 2 hours. I imagined this game to be less "stressfull", like, nobody is playing, i bet, i leave, i'm 50% sure i'm going to get back in 2 hours, if i don't, i won't loose, both players will be refunded.


But yeah, speaking of the EVM, you are right, somewhere there must be the "play" saved.

[whysos3rious]

Yes that I can do.

Maybe 24hours would be the best time for expiration then.
so you have time to sleep, if it's late

0) Import the contract in Mist using the contract address and the contract ABI :

ABI at the bottom of this page : http://etherscan.io/address/0xDD88C4D189585B650a3FE3d0E39147fcca59Ec32#code
contract address : 0xDD88C4D189585B650a3FE3d0E39147fcca59Ec32

1) Encrypt your Hand with a secret (change it every time) on the website : matching-ethers.com/rps. ex input : secret = mamamia and hand = rock ex output : 0x694175464a29105b9e3743992e59ab09559add0bc3d8b16e0e0945f55f68b8f0

2) Send your encryped hand code (ex: 0x694175464a29105b9e3743992e59ab09559add0bc3d8b16e0e0945f55f68b8f0) with 0.1 ETH using the sendEncryptedHand function (in Mist).

3) Be matched with an opponent (follow progress on the real time website and cancel waiting if no opponent comes).

4) You have 2 hours to reveal your hand with the appropriate function. (ex: use revealRock with input your secret)

5) Receive 0.198 ETH if you win or if opponent does not reveal. In case of draw, receive 0.1 ETH.


How to interact with the contract ?

In mist wallet you open the contract that you have just imported and there you can see the interface of the contract. There you can select several functions.

For step 2 you need to use the function named sendcryptedhand . This function asks for an input of 32 characters: use the code you generated at step 1

At step 4 when you will reveal your hand, you use another function on the same page in mist : for instance revealRock and you provide your secret.

[whysos3rious]

The website is back up.

The contract has been updated following your request, the expiration time is now 24hours.
You can now play and come back in time to reveal, you can even sleep and reveal the next day

Thanks for the update, that's nicer like that indeed

[whysos3rious]

Ok everything seems to be working properly on the new contract

[whysos3rious]

Don't forget to change your secret every time you play and to use 10 letters/numbers.

You can keep the website open or notepad to store your secret until you reveal.
