If I did what you said, I would be denying someone a win and most likely giving someone else one.. Anyhow, there is a house edge. Casino's don't have to cheat man.

Do you know how they come up with the last 16 decimals? I get that 2 decimals come from people buying and selling Bitcoin. Where does the rest come from?

When I buy or sell Bitcoin, I only get to enter 2 decimals. Maybe it comes from trades against altcoins or other currencies too, but still, the "accuracy" is meaningless. To quote from another discipline: "the end calculation should not have more significant digits than the original set of data".

Out of curiosity, why don't you think the rest come from trading? Could be simply a matter of displaying 2 decimals but backend handles with more precision.

You can add start and end's to our API. To show historical prices. I will post some examples shortly.

Unless there's an even distribution of bets (which is unlikely to happen every time), it's still possible to cheat.

I've seen online casinos cheat. If you're honest, there's absolutely no reason to make people doubt your honesty if you can make it provably fair.

Your argument falls apart if there are 50+ people playing.

straight from the two largest exchanges.

Even with API access, you'll never be able to fetch the data at exactly the same time as l0tt0 does.
I actually got here after seeing your signature campaign thread, and the part about the 16th decimal made me curious.

I think that's a bad basis to start from, for something that could otherwise be a nice (and unique) site.

this is our API: https://www.l0tt0.com/api/price.php
which you can view historic prices. it's 100% fair because at the end of the day even if you DON'T trust how I get the numbers- you can CLEARLY see that everyone is getting the SAME numbers. if we both play Quick Pick, and both bet on number 11, and both of us click place bet at the same time.. if the next price update (in 5 seconds) has 11 in the last 6 decimals (one of the three winning numbers of the game) we would both win. therefore there is no way I could show you one number and someone else another..

I love the design of this website already. It's just amazing and reminds me of 90's games man. I don't know, the theme looks like that way.

So you have three games so far, which are Quick Pick, Line Bingo, and High Low. They are as simple as they could be and easy to play on-site. Saw the Bitcoin price API synched with the timer. Makes it more authentic when playing it live.

Moreover, I understand that you have newly launched the game but I can see only two winners playing here that is Boxxob and Josh. Also, I can't see losses here. Are they not shown intentionally OR...?

Hope so you will shed some more light on the above questions.

You should also get a good thread designer and have an amazing ANN. Refer to other casinos and since you have already good UI you should launch with a grand entry. Good luck.

It doesn't change the problem of not being able to verify the exact same result.

Combine block hashes (see for example bitmover's Giveaway Manager) with a seeding event (see for example RHavar's Provably Fair Seeding Event). It could be setup in such a way that results can be verified right after each new block was found. Or, now that I think about it, it could work entirely without block hashes and only use random data from the seeding event. I know it's not as cool as using Bitcoin price data, but I've never met anyone who uses that up to 16 decimals anyway.

One thing I considered: What about using these decentralized exchanges / swap sites like Uniswap?

Being used to provably fair, I agree it would be best if the results could be verified reliably. Unfortunately nothing comes to my mind how to keep the current, unique idea, but with provably fair results.

I considered setting something up to keep my own file of l0tt0.com results so that users could verify from my version that the results on l0tt0.com were the same for them as they have been for me. I think the best would be if us players could fetch the same details from Coinmarketcap and Coingecko and verify the results that way. I considered possibility of setting something like that up too but I cannot dish out cash for paid API personally for that.

I guess it is a bit of a blackbox how Coingecko comes up with the result. As far as I understand they also use the Coinmarketcap API. And in both cases they use a paid API so we cannot see the results for free.

@dewez: please fix your quote.

Your link shows 12 decimals, but the question remains the same: where does it come from? It's not as if the last decimals are "live", the price changes only every few seconds, and when it does, all decimals change. So it makes absolutely no sense to go that "accurate", and I can't find how CoinGecko comes to this result.

It's still possible to cheat: even if everyone gets the same numbers, you could pick numbers in such a way that you maximize your own profit. Say someone with a $10 should have won, but instead you make someone else with a $1 bet win.

there is the public facing api-goes to I think 11, 16 char is normally the high end of precision... the reason that public one has 11 decimals because there are 5 digits before the decimal point.. which takes 5 from 16, thus 11. We have a custom production one. same with marketcap.

Your site looks very "old" with the graphics and fonts coming from the old Builtin board days. I looks like the ancient arcade games that I played when I was still very young.

It might sound if I am harsh, but I am just brutally honest and I hope you see this as constructive criticism. I do not know if you are deliberately going for a 80s look, but I think it is too dated, compared with your competition.  

Can you share exactly how I could reproduce your 16 decimals? I've only seen Bitcoin prices with 2 decimals in dollars, and that's what most (if not all) exchanges use too.
It doesn't look like this can be made provably fair, which means it's trivially easy for you to cheat. I'm not saying you're cheating, but if it's not provably fair, players can never know for sure.

We log every one of our price updates and give you full access to them.


One way to creating multiple rolls per Bitcoin block would be by mixing it with some sort of crash seeding event. At least that would make it provably fair, although the cut-off for new blocks, especially if you get an orphaned block, will still be tricky.

That's what signed messages are for.

The project has instant games with a unique take on where the winning numbers come from . They're taken from the last decimals of Bitcoin's USD price. We source our price information from two esteemed platforms, CoinGecko and CoinMarketCap. We have custom API's which deliver us updates every 10 seconds. We call one, sleep 5, then call the other. each is added with the last and divided by two. Thus giving us a steady price update every 5 second, going down to the 16th decimal.

i thought of that.. but thats every 10 minutes.
l0tt0's games are instant.. so that 5 seconds inbetween games is key.

As for the wallet, thats not a bad idea.. but I could be posting anyone's wallet.

it's 5 to start. that will grow for sure. we want to get quality and build long term relationships with our sig people. it would be just silly to start with 20... the only reason to do that is to be loud.. i'm not loud, i'm strategic and in this for the long haul. ...time and pressure.
