EDIT:
We had initially tried to write the code for our Chinese lottery platform from scratch but found it very difficult to complete due to our urgent timeline. Instead, we forked the Pancakeswap lottery and made some changes to the rules then implemented it on our platform.
Rules:
NIUPOT Fee; 1 ticket: 10 NIU
Single User NIUPOT Entry Limit: No limit on total tickets, but maximum of 20 tickets per each batch purchase (all tickets will consist of different numbers)
Each one ticket will give participant a random 4 digit combination with each digit being between 1–8, for e.g. “7–5–8–4”
How to win:
To win the NIUPOT pool (50% of the entire NIUPOT pool), users need to match all 4 numbers on their ticket in the same position (order) as the 4 winning numbers.
If you don’t match all 4, you still have a chance to win. As long as you match 2 or 3 numbers in the correct position, you are guaranteed to claim a reward.
Winning Prizes:
First Prize: Match all 4 numbers in the exact position= win 50% of the pot (or split the pot if there’s multiple winners).
Second Prize: Match 3 numbers in the exact position = win or split 20% of the pot (or split the pot if there’s multiple winners)
Third Prize: Match 2 numbers in the exact position = win 10% of the pot (or split the pot if there’s multiple winners)
We will always burn 20% of the pool.
For example; the final 4 winning numbers are “7–5–8–4”:
“7–5–8–4” = match all 4 in the exact order; win or split 50% of the pot
“7–5–8–1”= match 3 in exact order; win or split 20% of the pot
“1–5–8–4”= match 3 in exact order;win or split 20% of the pot
“7–5–0–7” = match 2 in exact order; win or split 10% of the pot
“1–5–8–1” = match 2 in exact order; win or split 10% of the pot
“7–4–7–3” = match 1 in the exact order, lose
“5–7–4–8”= match 4 but not in the exact order; lose
Note — in situation when no participants matched 3 numbers in order, 20% reserved for the winners will be burned.
Beginning of each NIUPOT, we will add 500 NIU to the pool on top of the previous un-won pool.

How are ticket numbers drawn?
NIUPOT uses the Chainlink VRF (Verfiable Random function) smart contract as a tamper-proof RNG built for any applications that rely on un-predicable outcomes. Therefore, is no chance that anyone is able to predict the 4 winning numbers ahead of the drawing phase.
GOOD LUCK!!!
