Myriad offers flexible bets. You enter the amount you want to bet and the amount you want sent if you win and it offers you odds. You can accept the wager by sending payment.

The max bet, win amount and effective fee (lower odds than 'fair') depend on how much is in the wallet.

We're testing with real money, but a smaller wallet for now. Because the effective fee is determined by the percent of the wallet you are trying to win the fee will be higher now for the same wager compared to after the wallet is fully loaded up.

The games are cryptographically provably fair. We use sha256 to hash [junk, timestamp, our guess] when you first hit the site. After the wager is completed we reveal [junk, timestamp, our guess] and you can check that the guess is the one we committed to at the time you came to the site.

Since wins are determined by how close your guess is to ours you don't need to worry about how we select our guess.

Please give feedback! And ask questions if anything is unclear.

Max bet has been raised! Right now you can bet .01 to win 19.70!

Uh-oh. I'm pretty sure I bet on the number being 6000, but I'm not positive. Me and my memory, I tell ya
Sent coins to 13e8q1PtDNAXPGci7v5Jpz53FXLEwY5RTV and the hash of the bet was d8212b6ef695128b4014910df1e632706279bb22ac5b769f0876a0343f5e8346

I'm assuming I didn't win? How do I get notified of a win/loss?

I just changed it to say, "After you pay, click here to see if you won!"

Is 9999 'within 10 of' 0001?

ie. do the numbers wrap around?

Edit: I can answer that now.  I lost my bet, with "Guess: 3536, Number: 8930, Distance: 4606, Max Distance: 3536".

8930 - 3536 = 5394
13536 - 8930 = 4606

So they do wrap around - the reported distance is the shorter of the two.  It would be worth mentioning that (more prominently, if I missed it).

The string that was hashed for me was:


I would suggest putting spaces in there between the junk, the date, and the guess, just to make it more legible.

Thanks dooglus. Keep it coming.

I'm not sure about having the odds get worse the more I bet.

That encourages me to split my bet into 10 smaller bets to get better odds.

It just told me: "Hash or timestamp has been tampered with.
To keep things fair, games are only valid for 2 minutes, please generate a new hash."

I didn't tamper with anything.

I did hang around longer than 10 minutes though, looking at the odds it offered me.

I'm guessing the 2 minute limit is to prevent me brute-forcing the hash to find out what the number is.  How about making the 'junk' an extra character or two longer, and having the games valid for an hour instead.  2 minutes arguably isn't long enough for a new user to find their wallet address, copy it into the form, get familiar with how the site works, decide what numbers to type into the boxes, etc.

And instead of making me click a link to "generate a new hash", how about just generating a new one right there and then.

Also, I keep having to re-type my wallet address.  The input field isn't remembering the one I used last time, like input fields usually remember things.  I keep having to go back to my wallet and copy/paste it each time.

Oh, and where's that dime you promised me?  

Dimes coming to you and the 3400 guesser!

Yeah, I will increase it, I think 15 min for now. I can't just make a new hash silently since that would defeat the promise, I think there has to be notification/action.

Let me see about the remembering.
