On Coinslot, the 100% randomness of our games is guaranteed.
And the randomness can be checked through the "provably fair" tool which protects the game statistics not be modified by anyone, users can check it at any time.

Though the relevant techniques are complicate, the "provably fair" tool can be explained in a simple manner:

1. Client Seed: a string of characters provided to you before placing a bet.
2. Random Number: a unique string of characters generated by the system before placing a bet.
3. The Hash of Random Number: one and only characters correspond to the random number.

How the provably fair system applies these three components?

First, the system follows two rules:
1. The platform has no idea about client seed before user placing a bet.
2. Each random number has a corresponding hash, these two statistics will be revealed after the result comes out. A user can only see the hash before placing the bet.

Reasons for making rules：

Since Coinslot has no way to know client seed in advance, the platform cannot cheat.
Before revealing the result, only the hash of random number is seeable, so that you can check transparency of result later.

How does it works?

After placing a bet, user's browser will send the client seed to Coinslot server.
And the system will calculate a bet hash according to client seed and the random number through the SHA-512 cryptographic algorithm.
Then use the first 3 characters of the bet hash to generate the outcome of your bet.
The system does this by converting the first 5 characters of the bet hash from base 16 (hexadecimal) to base 10 (decimal).
If this number is over 4,050 then the next 3 characters would be used for the modulo operation.
The decimal number is used to calculate the bet result through the modulo 54 operation, and 0-53 correspond to 54 types of the playing card.

How to verify the random number?

The random number will be shown when bet result comes out.
Users can use any free SHA-256 generator to verify the hash of a random number.

Note: If two hashes you got before and after placing the bet are the same, it means the bet result is unmodified and 100% random.

What is LuckyCoin?？

LuckyCoin is the global leading blockchain-based game. Players could use only 0.01 ETH to win 1 ETH or more. By using blockchain technology, all the information and process are transparent and fair. Don't hesitate, play now!

How to play the game?

1. Choose one bidding type
2. Pay for your bid and get the bidding number
3. Wait for the draw (after all bids of one bidding type are sold out or time's up)
4. If your bidding number matches draw number, you win the reward.

Example

1. For 1 ETH bidding type, players can bid 0.01 ETH to win 1 ETH, and the bidding times of "1 ETH" for all players are 100. Players will get a bid number after bidding.
2. Players can bid one or more times for each type.
3. When there is no available bids or time's up, the system will calculate the "Lucky Number". If your bidding number matches lucky number, you are the winner!

Draw

1. The game will record the closing time of the round.
2. By using hexadecimal, the last 6 characters of the hash generated after starting the draw will be converted into a decimal number.
3. Divide the decimal number by total bids, then add 10,001. That is how the draw result comes from.
You can check the information about hash on etherscan.io at anytime, all information is completely transparent.

What is Lucky 11?

Lucky 11 is a decentralized lottery product based on distributed ledger technology. Each draw is provably random and cryptographically secure thanks to the nature of the Ethereum blockchain. Blockchain-based data are featured with its unchangeableness and recognized by the whole network, which means it can completely avoid black box operations. Thus, issues like information asymmetry or non-transparency could be addressed to give players a game platform with maximum fairness they have never enjoyed before.

How to play the game?

Players could randomly pick 1 to 5 numbers from 1 to 11 and submit it to the Ethereum blockchain. One draw per minute. The result is determined by the last hash value uploaded in the minute. If the chosen numbers match the draw result, the player wins the reward (virtual currency) stipulated in smart

Players will pick 1-5 numbers from 1 to 11. Players win the reward when the chosen numbers are in line with that of the draw result:

Type	Winning Probability	Reward
Pick 1	5/11	1.8x
Pick 2	1/5.5	4.5x
Pick 3	1/16.5	13.5x
Pick 4	1/66	54x
Pick 5	1/462	378x

How to win the game?

After closing the bet, all the betting information will be calculated through the Merkle Tree to get the Merkle number. And the Merkle number will be uploaded to the Ethereum, then get the hash value of this transaction's block. The last 25 digits of the value will be divided into 5 groups. Each group has 5 numbers, and it will be converted into a decimal number. The first group numbers will be processed through (x mod11 + 1) calculation. Then retrieving its current value as the first lottery number. The second group numbers will be processed through (x mod10+1) calculation, and by using the same method, the second lottery number can be drawn, and the rest can be done in the same manner. Finally, the five numbers calculated through this method will be the draw result.

How to ensure fairness?

1. Unchangeable betting information
The draw result is based on a hash value which was calculated from Merkle number. Since Merkle number has already uploaded to the Ethereum chain, the information cannot be modified.

2. Fair draw
The draw numbers are selected from the hash value, due to its unpredictability and unchangeableness, the fair draw can be assured.

3. Fair reward
Both draw and reward distribution are based on Ethereum chain. Thus, there is no chance for the platform to interfere. All information and process is transparent and fair.

4. No robots
Since all process is transparent and unchangeable, the platform cannot use any robot to do black box operations. The game is utterly fair.

幸运扑克怎么玩

当你在Coinsgame平台上玩游戏时，你相信游戏的结果是随机的100%。
我们将使用“可证明公平”工具来确保我们的游戏的结果/结果是100%（完全）随机。
这个工具使得我们不可能在任何时候改变结果，并且所有玩家都可以使用独立的服务来检查或确认任何结果是否确实是随机的。

技术虽复杂，但概念很简单。这个“可证明公平”系统共三个主要组成部分。

1. 客户端种子：在提供赌注之前提供的字符串。
2. 平台随机数：平台在你下注之前产生的独特的字符串
3. 随机数hash值：与平台随机数对应的唯一哈希字符串

可证明公平系统如何使用这三个组件？

首先，系统执行两个规则
1. 平台在你下注之前不会知道客户的种子。
2. 在你下注之前，你只会看到随机数hash值。这个hash值与我们的随机数一一对应，直到系统产生结果才会公布最终的平台随机数。

设定规则的原因

该工具阻止了Coinsgame了解您的客户种子，以便Coinsgame无法通过更改您的押注结果进行欺骗。
该工具在计算结果之前与您共享随机数HASH值，以便您以后能够验证结果是随机的

它是如何工作的

当你下注时，你的浏览器然后将你的客户端种子发送给Coinsgame服务器。
然后我们使用你的客户端种子和我们的平台随机数来计算出一个合成随机数。
用于此次合成随机数的算法是SHA-512加密算法。
然后，系统使用合成随机数的前3个字符从十六进制转换为十进制来生成下注的结果。
如果选出的数字大于数字大于4050的话依次取下一个3位，然后这个3位数参与取模运算。
该十进制数通过模54运算计算出最终开牌结果，0-53分别对应扑克牌中的54种牌型

您如何验证随机数

当Coinsgame显示您的投注结果时，它还会同时显示平台随机数。
然后，您可以在任意网站使用 免费的SHA-256生成器 确认平台随机数的哈希值与您下注前显示给您的随机数hash值相同。

注：在您下注之前显示随机数hash值，如果游戏的结果是100％随机的（即，赌场在任何时候都没有改变结果），则生成的合成随机数必须匹配。

什么是Lucky Coin？

LuckyCoin是世界上第一款基于区块链技术的类众筹玩法，在这里您可以使用如0.001ETH的小付出去赢得1个ETH甚至更多的数字货币奖励，
通过使用区块链技术，开奖算法公平、透明、公开、玩法新颖，快来体验吧！

游戏怎么玩？

1. 选择一个场次
2. 支付该该场次并获得投注号码
3. 等待系统开奖（当开奖倒计时结束时或者场次筹齐人数时开奖）
4. 若号码匹配则获得该场次奖励

玩法举例

以一场价值1ETH的场次举例子：
1. 比如该1ETH场次被平分为100个幸运等份，每个用户仅需要出0.01ETH，即可获得一个投注号码
2. 每个用户都可以在这个场次里购买一注或者多注投注号码
3. 当开奖倒计时结束时或者场次筹齐人数时，系统将开始计算“幸运号码”，当你的投注号码和幸运号码数字一致时，你将赢得该场次的1个ETH奖励

游戏怎么开奖？

当开奖倒计时结束时或者场次筹齐人数时，游戏将所有本期投注信息进行Merkle Tree计算，得出Merkel number，并将Merkel number上传至以太链；
信息打包上链生成的Hash值，使用最后六个十六进制数转成十进制数，然后对该十进制数进行求余，将余数加上10001即得到最终的开奖结果。
用户可以随时在etherscan.io里查验开奖哈希，它是十分透明公开和公平的

什么是Lucky 11？

Lucky 11是一款基于分布式账本技术的去中心化的彩票产品。鉴于以太坊区块链的性质，所有抽奖结果都是加密安全的且随机可查。
区块链上资料具有全网共识，不可篡改的特点，使得Lucky11区别于传统游戏平台，安全杜绝了传统游戏中存在的暗箱操作，
以及用户间不对等挥着游戏规则与信息不透明等问题，从而为玩家提供一个最为公平的游戏平台。

游戏怎么玩？

玩家可以从1到11选择1到5个数字并将其提交至以太坊区块链。每分钟进行一次开奖，开奖结果由每分钟上传的最后一个区块的哈希值决定。
如果所选数字与开奖结果相匹配，则玩家赢得智能合约中规定的奖励（虚拟货币）。
Lucky11玩法，用户从01至11的号码选1个或者多个（至多5个）号码组成一组号码，若开奖数字与所选号码一致，则用户获得对应奖励：

玩法	中奖概率	回报
选1	5/11	1.8x
选2	1/5.5	4.5x
选3	1/16.5	13.5x
选4	1/66	54x
选5	1/462	378x

游戏怎么开奖？

每期游戏投注结束，游戏将所有本期投注信息进行Merkle Tree计算，得出Merkel number，并将Merkel number上传至以太链; 信息打包上链生成的Hash值，
将对其最后6位进行分割处理，使用最后六个16进制数改成ASCII码，并对其进行 (x mod11 + 1)的处理，第二个号(x mod10+1)，
以此类推。每次选出号码后去除该位置的号码，然后进一步重排，并去除新的所在位置号码直至只剩5个，即为开奖结果。

怎么保证的公平？

1. 投注信息不可篡改
游戏开奖区块为上传的Merkle number的区块Hash值，即投注信息已经完成上链后才开奖，信息无法进行篡改。

2. 开奖公正
开奖选取的是上传的Merkle number的区块Hash值，这个值无法提前预知，也无法进行人为修改，开奖结果完全随机。

3. 派奖公平
开奖、派奖完全在链上实现，派奖流向完全基于开奖结果决定，平台无法干涉。

4. 无机器人
因投注、开奖的完全随机，且信息完全透明，平台无法也无利益引导进行机器人设置，从而分散用户奖池的获利。
