### **Specifics**

* Lottery Ticket Fee for 1 ticket: 10 EBEN
* Single User Lottery Entry Limit: No overall limit, but only 10 tickets with random numbers or 5 tickets with custom numbers can be bought at one time through the UI
* One ticket with a 4-digit combination is generated after the payment. Each digit ranges from 1 to 14, e.g. **"**1-9-3-2"

### **How to win**

To win the lottery jackpot (70% of the entire lottery pool), users need to match all 4 numbers on their ticket in the **exact same order** as the 4 winning numbers.

If you don’t match all 4, no need to worry. As long as you match 2 or more numbers in the correct order, you are guaranteed to win a prize.

For example, if the final 4 winning numbers are "1-9-3-2**"**

* "2-3-9-1" = match 0
* **"1-9-3-2" = match all 4**
* "1-9-2-2" = match 3
* "2-3-3-2" = match 2
* "1-2-1-2" = match 2

### **Winning Ratio**

* Match all 4 numbers in the exact order = win 70% of the pot (or split the pot if more than 1 winner). 
* Match 3 numbers in the exact order = win or split 20% of the pot.
* Match 2 numbers in the exact order = win or split 7% of the pot.
* Burn the remaining 3% of the pot.

Please note - in the event that no participants were able to win a price pot on any draw, the amount allocated to winners will then be passed to the next round.

### **Lottery phases**

Each full lottery session is completed every 3 days, with the timings as below:

Day 0, 3 AM  - Day 3, 2 AM (UTC)

An example of a lottery session starting at Day 0, 3 AM (UTC) is as below:

**Phase 1 - Buy Tickets (Day 0, 3 AM to Day 3, 2 AM)**

* You have 71 hours to buy tickets. 
* The lottery total price pot will accumulate at the top of the page with each ticket bought.
* Users will receive a ticket (comprised of 4 digits) for each 10 EBEN paid.

**Phase 2 - Lottery Draw! (Day 3, 2 AM)**

* The 4 winning lottery numbers are drawn and will appear on the page. 
* Each participant’s winnings will be automatically calculated based on their ticket numbers and shown on the page.
* Users can claim winnings if they have any.
* Users will also be able to see the lottery results: How many users matched all 4 numbers, 3 numbers, and 2 numbers. 

Please note - Users don't have to claim winnings before the next round starts. They can claim winnings of the past rounds at any time.

**Phase 3 - Celebration and Sharing (Day 3, 2 AM - Day 3, 3 AM)**

If you won, congrats! Share with your friends or in our community groups.

The next lottery starts in 1 hour!

### **How are ticket numbers drawn**

The lottery aims to be completely random. Even though the ticket numbers given out are determined by a front-end logic, it is almost impossible that anyone is able to determine the 4 winning numbers ahead of time.<br>

* The 1st lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the number of participating users at the entry deadline.
* The 2nd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the total pooled EBEN balance at the entry deadline.
* The 3rd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the timestamp of the last lottery participant at the entry deadline.
* The 4th lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the block difficulty at the entry deadline.
