CoinsGainer.com - provably fair multiplayer game of chance

[Idrisu]

CoinsGainer.com

CoinsGainer is a multiplayer bitcoin game of chance.

How to play:

Make a bet before the round starts and watch the multiplier grows in real time starting from x1.00. During the round you can cash out any time you want, starting from x1.01 by pressing the button "stop gain". Your payoff will be equal to bet times the current multiplier. The longer you stay in the game, the higher profit you will get. But, keep in mind, the gaining may stop at any moment. If you fail to cash out before or round result is exactly equal to x1.00, you will lose your bet.

How provably fair works:

We have generated a secret string and get its sha256 lowercase hexadecimal hash. This hash is representing a game #25,000,000. The game #24,999,999 is represented with the sha256 lowercase hexadecimal hash from the previous game hash, and so on. In this way, all games are represented by hash chain, that excludes any intervention by it's nature.

The result of each game is calculated by simple algorithm below (Javascript, CryptoJS library required), that uses a salted game hash:

Code:

const CG_GAMES_SALT = ''; // lowercase hexadecimal hash representation of unmined bitcoin block #572,752 here
const CG_MSB_NUMBER = 52; // MSB number (https://en.wikipedia.org/wiki/Bit_numbering#Most_significant_bit)
const HEX_ENCODING = CryptoJS.enc.Hex;

// computation logic
const CG_GAME_RESULT = (gameHash) => {
    gameHash = CryptoJS.HmacSHA256(HEX_ENCODING.parse(gameHash), CG_GAMES_SALT)
        .toString(HEX_ENCODING)
        .slice(0, CG_MSB_NUMBER / 4);
    const hashResult = Math.floor(99 / (1 - parseInt(gameHash, 16) / Math.pow(2, CG_MSB_NUMBER)));
    return Math.max(hashResult / 100, 1);
};

The salt is a constant and equal to lowercase hexadecimal hash representation of unmined (at the moment of making this post) bitcoin block #572,752. This way, such salt is a proof that the hash chain was NOT chosen deliberately with unfavorable game results for the players. First game hash is: 4790d1e1b91bd559cbd228e713fa85749443c0030b0036ae6b500e82d6490630

I see this gambling website last week but I still not try to observe it because I am busy. Can someone tell me if this is like a crash game that similar to bab gambling site? I would like to try it if that's the case.

yeap , this is your regular crash game , but the results are displayed in a form of a speedometer
the rest is usual - multuplier goes up until it crashes , those who press collect before it crashes get paid
there is nothing really special about the site , maybe the free faucet
other than that , their chat is deserted , there are no interesting promotions running etc.

Thank you all for the feedback. It's extremely important for us. Every single day we doing our best with your help to become better than we were yesterday. Every question, suggestion or just comment greatly help us in that. I will answer to the most popular question asked here in regard to our nearest future plans (in order of priority), briefly:

• advertising campaign launch
• advanced player stats
• autobetting online/offline feature

I personally liked the idea of merging a dice layout with the added spice of a burst like moneypot (which you call 'chance' here). Have some questions though:

1 - Why are we not allowed to make more than BTC0.0374 per bet? (Max Gain: BTC0.0374)

2 - How much maximum can it go higher in number? (How many times exactly? Like 1000x, 10000x?)

3 - As I have not signed up yet, may I know how much free BTC do you give to your users?

1 - Why are we not allowed to make more than BTC0.0374 per bet? (Max Gain: BTC0.0374)

Those limits are floating and strongly depends on current bankroll size, which is currently not very large.
Check our FAQ section for details.

2 - How much maximum can it go higher in number? (How many times exactly? Like 1000x, 10000x?)

Thanks to calculation algorithm nature, there is no any limits on maximum multiplier.
Few days ago, for example, you could see 69,677.19 as the result of 48077th round.

3 - As I have not signed up yet, may I know how much free BTC do you give to your users?

You will receive free 10 satoshi per request.
Faucet terms are fully described at our FAQ section.

Good luck!

Yes, CoinsGainer.com Probably Fair Multiplayer game. There are many interesting and interesting features here that give the best experience of the players. Some of the main features are free faucet, automatic deposits, instant withdrawals, multiple windows bets, mobile-friendly, etc. I like mobile friendly and multiple windows bets. There are not many windows bets on many online sites but here they are. I have never heard anything bad about CoinsGainer.com and considering all aspects, I think CoinsGainer.com is probably Fair Multiplayer game.

This is one of a good thing to have, because players is everything here. The problem is you have thousand players registered and only 20 online and 5 playing. And I check the stats of your game, max bet is only 0.03, same to the max gain. I wondering how much multiplier can we get here, in past 10 games, I never saw any multiplier out from 2.5x. May be I should do more but overall I can say, this site need to have more bankroll to increase its player and the wagering amount

Undoubtedly.
Currently, we are too young to afford a large bankroll.
Sweety investment program is on the way.
Thank you for your feedback.

a public bankroll sounds like a good idea at this stage
you cannot afford a big bankroll being a new site , but if you offer good investment plan and ensure your investors feel safe investing into you
it could give your site a big boost , will be hard to compete , still , but you can find your niche for sure
keep working on the site , add new features and think of some nice promotions and you can succeed

[jarolee]

Stay tuned so you don't miss upcoming opportunities and features.
Thank you @veleten for the kind words!

Congratulations on the achievements, I hope that the number will grow in the future so you can get more players who will play on the site.
We will wait for the upcoming opportunities and features, and we hope that it will be something good for members and of course for the site itself so it will help the site to bigger.
I am trying to register to your site and get a free satoshi to play.
Playing for a small amount with 1.01 gain will be good for me as I can win over and over hahaha

Stay tuned so you don't miss upcoming opportunities and features.
Thank you @veleten for the kind words!

We are all waiting to when we can have the mobile version of the game's on your platform, I have played and win some games and I will want to do better when am able to play on mobile devices because I will be able to play games on the go without having to stock to my computer for a long time. I love the Bank roll investment where users can earn by investing on the bank roll and gain percentage from the house edge.

The game is initially designed using mobile-first strategy.
Could you clarify, please, what difficulties you encountered with using a website on a mobile device?
With regard to keep playing while offline, right now we are working hard on autobet feature with both of online and offline modes.
Looking forward your reply soon )

This seems really interesting and I would love to play it. I have already visited the site and bookmarked it to start playing later when I get chance to. But on that features you have mentioned ,there is something I don't really understand , you mentioned free faucets and that users are getting free faucets after sign up.

Do you mean like real faucets? Or you mean that the site has a faucet users can claim free satoshis to play the game? If so, I'm hoping there isn't going to be so much if annoying ads just like most faucets are these days, cause I know a lot of faucets that are pretty annoying with ads and that's one of the reasons I dislike faucets .

Just free satoshi to play the game without bullshit.

Why dont you take what veleten said? By opening a public investment, this is sure to make your site trustable and gain more people to play. For the current time I do not think you have more players, even if you do, they do not wagered big right? Bankroll is really needed and is a important thing to have for such a young site.

Are you saying that you never play crash game? This is exactly have the same concept as any crash game before. And for the faucet, you just claim as usual and for the bonus it is a normal thing for the new site to have

As I mentioned it before, currently, public investment at the development stage.
The feature will be released approx. within a few weeks, right after autobet.
Thank you!
