    Dear all!

    Just a suggestion but more like a little joke... What about lava lamps?
    (Not sure that there is an API to access this wall .)

    Cheers!

    Okay Ill take 18,20,32,25,69,121,256,512,744,769 please.

    - - - Updated - - -

    Redraw until it is a used number.

    Just a thought to keep it transparent you need someone with absolutely no interest in this draw to go online with a PC capable of recording video to hard disk - generally nvidia cards are good at this with their shadowplay option at an exact specific time generate a random number on this site.

    https://www.mathgoodies.com/calculat...ndom_no_custom

    Or maybe live stream the draw on twitch - then everyone can watch.

    I spoke to Tim Prior to Christmas and we have agreed that the competition will close at Midnight (GMT) on the 31st December.

    The draw will take place on the 5th January at an agreed time. (Work commitments on my side will hold up the draw until then as I need to check all the chosen tickets are correctly allocated).

    Any entries after the close of the competition will be refunded and will not be entered into the draw.

    All we have to do now is to find a fair/verifiable method to make the draw. So please post any methods you can think of in this thread.

    Tim is available for the week beginning 7th January to get the system posted out to the lucky winner.

    So if you want a chance to win the 4000D you had better get buying some tickets.

    Thanks

    Go to https://random.org/lists/ and click Switch to Advanced Mode, paste in the list of sold tickets, select Use pregenerated randomization from 2019-01-05 or whatever future date you decide on, click Randomize, and the first ticket in the list is the winner.

    If you haven't got the time to format the PDF as a plain list, then use a list of the numbers 1 through 1000 instead, and start from the top until you find a sold ticket.

    This is as simple and fair as it gets, and anyone can verify the result in less than a minute.

    @Leffmann

    Thanks for the suggestion.

    The numbers taken to date are in a table but also in a text list with the Forum name next to it. So I should be able to squirt that straight in.

    I'll give it a go over the weekend and see how it goes.

    @tbtorro

    I normally moderate out the ticket number posts and to be honest I was in a rush and just replied to confirm the numbers had been entered.

    I'll tidy the thread up but it's a byproduct of the competition area.


    The competition area was originally set up for members to post answers to a quiz and as such all replies except for Mods/Admins are auto-moderated.

    This stops members seeing their posts and allowing them to check that they had typed their choice in correctly.

    The competition closes tomorrow night at midnight so it should be back on subject then.

    In the meantime I'll hopefully keep on top of the moderating out non-conforming posts.

    @Leffmann

    I've just tried your idea with 50 numbers (1-50) with todays date as the seed.

    It seems easy to use and is verifiable by anyone.

    Attached is the result I got from it tonight

    One thought:

    The outcome is obviously affected by the order of the entries in the list. Decide on an order to use and post the definite and final list shortly after the competition has closed, otherwise someone can cry foul and say the list was ordered at the date of the drawing in a way that resulted in a favorable outcome.

    One way is to decide beforehand that the list will contain only the sold tickets, in ascending order with ticket #1 at the top.

    I pushed the 50 numbers I did in numerical order as you state the order did make a difference - I pushed the outcome back in as an input just to check the outcome.

    So I'd assume we push the numbers in in numerical order.
