HELP
Registration:
To register you only need to inform a Bitcoin address, preferably one that you can sign messages with as some features are only available through message signing (Bitcoin Core client format), and a password. You can also specify a login if you want.
We require signatures as a security measure in the following activities:
  • Reset your password;
  • When spending more than 5 BTC (this is the default value, it can be changed before the registration or on your profile) buying tickets or quotas between two draws;
  • Adding other main addresses (that can be used to sign messages), permanent or temporary withdraw addresses;
Important:
We strongly recommend that you use a wallet where you are in control of your private key (like Bitcoin Core or Blockchain.info Wallet) to avoid problems in the future.
Depositing Funds:
Everytime you want to deposit funds to your account, you will get a temporary deposit address that will last for 24 hours.
When making a transaction to your temporary deposit address, your account will be credited automatically as soon as our server receive your transaction, but the credits will be shown as "Unconfirmed Balance". With an "Unconfirmed balance" you can buy tickets and pool quotas, but these will remain unconfirmed until your transaction reach 2 confirmation(s).
Withdraws:
To withdraw you just need to click on the "Withdraw" menu, fill the address and the amount and click the button "Continue".
The minimum withdraw value is 0.0000543 BTC
If you're withdrawing to an address that isn't registered in your account, you will need to sign a message with one of your main addresses to verify that you really requested the withdraw.
When withdrawing to an unknown address, you can add it to your permanent withdraw address list and also add a label to it, so you won't need to sign messages to withdraw to this address anymore.
The first thing you need to know is that we own the money that is informed in the jackpots. We will try to keep at least the value of our largest jackpot in our cold wallet address 1GrD6sUeJyjsFcFHqhTuYbwqbqYGQ2dAzY

And to prove that we own this address, here is a message signed with this address:

Pools:
The pools are created by the users and there are two types of pools:
  • Share-a-Ticket Pools are pools where the owner buy tickets and divide the price of the tickets by the number of quotas. The owner can also specify a service charge for the pool. Any prize won by the pool will be divided equally between the filled quotas.
  • Add-a-Ticket Pools are pools where each participant add a ticket to the pool and the owner can specify the minimum and the maximum amount of numbers per ticket in the pool. Each ticket added is considered a quota. Any prize won by the pool will be distributed proportionally to each quota based on its ticket value.
In both pool types you can define the pool name, description, adjust how many quotas the pool will have, set how many quotas should be filled and the minimum 6-Hits-Jackpot value for the pool to be activated, you can also set the pool private where it may or may not have a password. Private pools won't appear in the public pool list and will have a unique URL to access it.
Note 1: Active pools or filled quotas in active pools can't be canceled.
Note 2: Filled Quotas with unconfirmed credits will be canceled after 12 hours without confirmation.
Note 3: If a pool is used to any kind of spam, we reserve the right of making the pool private and activating it without further notice.
Draws:
The draws will take place Tuesdays, Thursdays and Saturdays at 24:00 UTC. In each draw, 6 distinct numbers in a total of 67 will be drawn. Each draw have an associated secret, Click Here to download the SHA512 hashes of the secrets for the next draws.
One and a half hour before the draw time, a file will be generated containing all the tickets that will participate in the draw and the acquisition of new tickets will no longer be available.
To prove that we won't touch the file after the generation of the winning numbers, we will timestamp with a Bitcoin transaction the hexadecimal SHA256 hash of the file containing the tickets.
At the draw time, we get the current block height and we will use the next block hash to generate the winning numbers. When we receive the block needed to generate the winning numbers of the current draw, the purchase of tickets for the next draw will be available.
To generate the winning numbers we wait for the chosen block to have 6 confirmations, then we concatenate the block hash (lower case), the block height, the server secret and the SHA256 hash (upper case) of the file with the participating tickets, then we calculate the SHA512 hash of the resulting string and repeat the following steps until we have 6 distinct winning numbers:
  1. Transform the hexadecimal SHA512 hash got on the previous step to a number in base 10
  2. Get the remainder when dividing the number got in the step 1 by 67
  3. Add one to the number got in the step 2
  4. If the number got in the step 3 is not on the list of winning numbers, add it to the list
  5. Get the SHA512 hash of the hexadecimal value used in the step 1
  6. Repeat if we still don't have 6 distinct numbers on the list
Investments:
Investments are available only to registered users.
Everytime the jackpot for 6 hits is lower than 1000 BTC, the investment will be opened so we can always keep the jackpot for 6 hits with a minimum of 1000 BTC. Here are the rules:
    - You can invest a minimum of 0.001 BTC;
    - The invested amount will go directly to the jackpot for 6 hits;
    - Half of the house profit will go to the investors (2%). You will earn income until you profit 50% of your initial investment. For instance, if you invest 1 BTC you will earn 1.5 BTC as income, this means, your initial investment plus 50% profit;
    - Unconfirmed Investments will be canceled after 6 hours without confirmation;
    - Profits will be credited in your account every top of the hour;
    - The divests requests will be processed right after the next draw. The amount will be taken from the 6 hits jackpot. If someone win the 6 hits jackpot, the divest amount will be taken from the reserve jackpot. Every time you receive profit from your investment, your divest amount will change. Let me give you an example: if you invest 10 BTC and if you already received 1.5 BTC as profit when you divest, this is the same you have invested 1 BTC, earned all your profit of 50% (1.5 BTC) and have kept 9 BTC in your account. So, in this situation you will be able to divest 9 BTC.
Now you can play without registering using the following addresses to buy random tickets:
Numbers In Ticket Address Price
6 16WZdBhUoeSyr8k5ktLtkKRmRvDHPvLWmY Multiple of 0.001 BTC

16 1MBbGKJzBqyJaJJ7VLTr6BsYGT41ycUoC7 Multiple of 8.008 BTC
If you already bought random tickets, fill the field below with your Bitcoin address or the transaction id to view the generated tickets:
          
The tickets bought through these addresses will be played on the next draw. If the transaction don't receive 6 confirmations until the draw time, the tickets will be played on the draw after the next draw.
You can buy more than one ticket at once per address, you just need to send a multiple of the price to the respective address. For example, if you want to buy 8 random tickets of 6 digits for the next draw, you just need to send 0.008 BTC to the address 16WZdBhUoeSyr8k5ktLtkKRmRvDHPvLWmY.
IMPORTANT: When playing without registration, if you win, we will return the winnings to the address that sent the amount to our address, this means you can't buy tickets through a service that use their address to send the transaction, like any Bitcoin exchange. You must send your transaction through an address you have control over it, like the client Bitcoin Core.
If you aren't sure from what address your wallet will send the transaction, we invite you to register. When registering you will get a temporary address that can be used to fund your account from any wallet. Furthermore, when registering you can participate on pools and also choose the numbers to your tickets.
We are the first Bitcoin lottery to offer a multi level affiliate program and you will receive profit from three levels below you. This means that you will win a percentage of the house profit when Player A that was registered through your referral link buy tickets (first level). You will also win when Player B that was registered through Player A referral link buy tickets (second level). And also you will when Player C that was registered through Player B referral link buy tickets (third level).
The percentage for the first level is 10% of the house profit, the percentage for the second level is 8% and the percentage for the third level is 7%.
So lets try an example: Lets suppose you referred 7 players. This means that if every one that you refered buy a basic ticket for 0.001 BTC you will receive 0.000028 BTC.
Now lets suppose that every player you referred also referred more 7 players each one. This means that if every one referred in your first and second level buy a basic ticket for 0.001 BTC you will receive 0.0001848 BTC
And once more lets suppose that every player referred in your second level also referred more 7 players each one. This means that if every one referred in your first, second and third level buy a basic ticket for 0.001 BTC you will receive 0.0011452 BTC.
And all this is considering only the basic ticket.
But that's not all, we also decided that everyone should have a referrer before registering, but we don't want to block registrations of players that reached our site clicking in our ads or through a search engine. So we created a score system.
After every draw we will calculate a score for every player that logged in on YABTCL in the last 30 days and the player with the bigger score will be the referrer of the players that didn't reached our site through a referral link. He will also be considered the referrer of all the random tickets bought by players that used one of our Anonymous Addresses until the next draw.
Events that raise your score: Investing, buying tickets, creating pools and buying quotas in pools.
Events that decrease your score: Wining shares of the jackpots, receiving profits from your investments, receiving revenue from the referrals, divesting and receiving profit from quotas bought in your Share-a-Ticket pools.
Let's see an example where a player:
  • Invested 10 BTC (+10);
  • Received 1.5 BTC from his investment (-1.5);
  • Divested 9 BTC from his investment (-9);
  • Bought tickets for a total of 3 BTC (+3);
  • Created a Share-a-Ticket Pool for a total of 2 BTC (+2);
  • Others players bought quotas in his Share-a-Ticket pool for a total of 1 BTC (-1);
  • Received percentages of the revenue from the referrals totalizing 1 BTC (-1);
  • Won shares of the jackpots totalizing 1 BTC (-1);
So, the player of the above example will have a score of +1.5 and if this is the highest score between all players at the draw time, all the players registered until the next draw that didn't reach the site through a referral link will be automatically referred by the above player.

The multi-level referral system also works with the free lottery. You will win a percentage of the winnings of players referred up to three levels bellow you. And the new players of our free lottery that reached our site without being referred will be automatically referred by the player with the highest score until the next draw.

You can find your referral link accessing the Referral menu after logging in.
Revenue distribution:
For each ticket bought, this is how we distribute the ticket value:
  • We take 4% to the house;
  • From the remainder, we reserve 6% to the next 6 hits jackpot, this means, after someone hit the jackpot for 6 hits, the acumulated amount in this reserve will be used to next 6 hits jackpot;
  • And the remainder we split it into the following:
    • 17% to the jackpot for 6 hits
    • 17% to the jackpot for 5 hits
    • 16% to the jackpot for 4 hits
    • 25% to the jackpot for 3 hits
    • 25% to the jackpot for 2 hits
To play our instant lottery you have to choose 1-16 numbers from a total of 67 available. The prizes will depend on the amount of chosen numbers.
If you want to try it before playing with real Bitcoins, you just need to check the option "Play for fun" and you will have 100 Play BTC to try the game and test your strategies.
We have an Auto Play option with some settings. When you start a game with the Auto Play on, it will stop only when you click on the "Stop" button or when one of the conditions adjusted in the Auto Play configuration is met.
If the Auto Play is on, a table will be displayed showing how many rounds were played, the current bet value, your winnings and the maximum profit got in the current game.
When playing using the Auto Play, if you don't wanna wait each round to be played, you can advance up to 1000 rounds per request.
Our instant Lottery is provably fair. Before each game we show the SHA256 hash of the secret that will be used to generate the winning numbers of the next game.
For each game started, we follow the steps below:
  1. Concatenate the secret with himself;
  2. Generate the SHA512 hash of the string got on the previous step;
  3. Get the first 7 characters of the hash got on the previous step and transform it to decimal base;
  4. Get the remainder when dividing the number got on the previous step by 67;
  5. Add one to the number got on the previous step;
  6. If the number got on the previous step is not on the list of winning numbers, add it to the list;
  7. If the list of winning numbers has 16 numbers, go to step 11;
  8. Remove the first 7 characters of the hash used on the step 3;
  9. If the string got on the previous step has more than 7 characters, go to step 3;
  10. If the string used on the previous step has less than 7 characters, concatenate the hash got on the step 2 with the secret and go to the step 2;
  11. If the Auto Play is on: stop if one of the conditions is met, otherwise concatenate the hash got on the step 2 with the secret and go to the step 2;
  12. If the Auto Play is off, stop.
Our referral system also works with our instant lottery. For each round played we pay 10% of the house edge for the first level, 8% for the second level and 7% for the third level. So if a player plays one round with a bet value of 0.1 BTC, the first level will receive 0.0001 BTC, the second level will receive 0.00008 BTC and the third level will receive 0.00007 BTC.
The above example is for games with 1% house edge.
Our instant Lottery has a variable house edge system. The house edge starts at 1%, but you can lower it up to 0% in the following ways:
Playing our instant lottery:  (Values for a 7-day window)
  • If your all your bets in our instant lottery totalize more than 10 BTC, the house edge for your games will be lowered by 0.1%
  • If your all your bets in our instant lottery totalize more than 30 BTC, the house edge for your games will be lowered by 0.2%
  • If your all your bets in our instant lottery totalize more than 50 BTC, the house edge for your games will be lowered by 0.3%
  • If your all your bets in our instant lottery totalize more than 70 BTC, the house edge for your games will be lowered by 0.4%
  • If your all your bets in our instant lottery totalize more than 100 BTC, the house edge for your games will be lowered by 0.5%
The minimum house edge you can reach with the above conditions is 0.1%
Losing in our instant lottery:  (Values for a 7-day window)
if you're playing a not automatic instant lottery game or an automatic one without the bet multiplier option enabled:
  • If your cumulative losses are greater than 10x the bet value of your next game, the house edge for the next game will be lowered by 0.4%
  • If your cumulative losses are greater than 100x the bet value of your next game, the house edge for the next game will be lowered by 0.6%
  • If your cumulative losses are greater than 1000x the bet value of your next game, the house edge for the next game will be lowered by 0.8%
The minimum house edge you can reach with the above conditions is 0%
if you're playing an automatic instant lottery game with the bet multiplier option enabled:
  • If your cumulative losses are greater than 10x the maximum bet value allowed of your next game, the house edge for the next game will be lowered by 0.4%
  • If your cumulative losses are greater than 100x the maximum bet value allowed of your next game, the house edge for the next game will be lowered by 0.6%
  • If your cumulative losses are greater than 1000x the maximum bet value allowed of your next game, the house edge for the next game will be lowered by 0.8%
The minimum house edge you can reach with the above conditions is 0%
  • If your cumulative losses in our instant lottery are greater than 0.5 BTC, the house edge for your games will be lowered by 0.1%
  • If your cumulative losses in our instant lottery are greater than 1 BTC, the house edge for your games will be lowered by 0.2%
  • If your cumulative losses in our instant lottery are greater than 1.5 BTC, the house edge for your games will be lowered by 0.3%
  • If your cumulative losses in our instant lottery are greater than 2 BTC, the house edge for your games will be lowered by 0.4%
  • If your cumulative losses in our instant lottery are greater than 2.5 BTC, the house edge for your games will be lowered by 0.5%
  • If your cumulative losses in our instant lottery are greater than 3 BTC, the house edge for your games will be lowered by 0.6%
  • If your cumulative losses in our instant lottery are greater than 3.5 BTC, the house edge for your games will be lowered by 0.7%
  • If your cumulative losses in our instant lottery are greater than 4 BTC, the house edge for your games will be lowered by 0.8%
  • If your cumulative losses in our instant lottery are greater than 4.5 BTC, the house edge for your games will be lowered by 0.9%
  • If your cumulative losses in our instant lottery are greater than 5 BTC, the house edge for your games will be lowered by 1%
The minimum house edge you can reach with the above conditions is 0%
Having one of the top 100 scores in our score system:
  • If your position is between 1 and 30, the house edge for your games will be lowered by 0.9%
  • If your position is between 31 and 60, the house edge for your games will be lowered by 0.7%
  • If your position is between 61 and 100, the house edge for your games will be lowered by 0.5%
The minimum house edge you can reach with the above conditions is 0.1%
As you can see, the conditions above were separated in groups.
The bonuses are cumulative between groups. This means for example that, if all your bets made in our instant lottery tatalize more than 30 BTC and your position in our score system is between 61 and 100, the house edge for your next game will be 0.3%.
Another example, if all your bets made in our instant lottery totalize more than 100 BTC and you own the first position in our score system, the house edge for your next game will be 0.1%. This is because the minimum house edge between the two groups where you met a condition is 0.1%.
Last example, if you have the first position in our score system and you have cumulative losses greater than 100 times the maximum bet of your next game, then your next game will have a house edge of 0%.
Note: If you're playing a game with 0% house edge in automatic mode, the game will stop automatically if you reach a cumulative profit greater than the maximum payout per bet and the house edge for your games will be raised accordingly to the conditions met in the above groups.
