How to play 6-45

You can play "Bitplay Club Lottery" every day. Simply choose your numbers on the ticket. You may choose the numbers yourself, or have it auto filled with random numbers. You may even choose to have frequent or rare numbers filled in by the system. Select how many consecutive draws you wish to participate: 1, 2, 3, 4, 5 or 6 draws. The number of consecutive draws means that you will buy the ticket with the same combination for the next day/days.

One lottery ticket costs 0.0001 BTC. The total price will depend on the number of options and tickets you choose to play.

How do we receive drawn numbers?

The draw is held every day. It’s closed at 08:00 UTC. Numbers checking starts in 2 hours after the draw close.

The Bitplay Club Lottery uses a unique system to find the winning numbers. We take every odd block from blockchain and based on its hash, height and hash of the previous block we calculate the drawn number according to the formula:

(
    crc32(
        md5(
            md5(<Previous Block Hash>) +
            md5(<Block Height>) +
            md5(<Block Hash>)
        )
    ) MOD 45
) + 1;

If the same number has drawn once again in this draw, we are waiting for the next odd block. We repeat the odd block selection till all 6 numbers are found.

  • You can easily check the numbers on every draw by visiting blockchain.info website for blocks checking and following the above mentioned protocol.
  • You can also check the drawn numbers using our calculator .
  • Winning numbers and the game prizes can be found on the draw page of the lottery as well as in the "My tickets" section.
Prize pool and distribution of winnings

60% of the total tickets sales goes to the draw prize pool and Jackpot while 40% goes to the service management, referral rewards, marketing/promotion of the project in order to increase tickets sales and make the game more interesting and profitable for everyone.

From the 60% we first take 30% and use it for the Jackpot increase.

Then we make payments to Group A winners.

The rest is considered to be as 100% and it is divided into Groups B, C and D:

  • Group A - 2 matching numbers - 0.0001 BTC
  • Group B - 3 matching numbers - 25%
  • Group C - 4 matching numbers - 33%
  • Group D - 5 matching numbers - 42%
  • Group E - 6 matching numbers - Jackpot

The prize pool of each group will be divided in proportion to the number of winning tickets in that group.

If more than one ticket hit the jackpot, the prize will be divided equally. The jackpot is accumulative and if it’s not hit by anyone, it will be rolled into the next draw. Bitplay Club reserves the right to channel some part of the jackpot commission but not more than 50% of it to the reserve funds and use it for future jackpot in case current jackpot is hit.
