    need a clue as to what 999999 has to do with Pi.
    I know that it is the 762 decimal place location.
    I know that it is an irrational number.
    Does it have anything at all to do with banking or the watermark?

    …19? I have the sequence of what happens when you click on them, but I can’t figure out the actual pattern that you have to click them in…

    I have just volunteered to give out hints. At the bottom of the puzzle, click the hint button.

    I type slow with two fingers so be patient. My email is mrpi@pidaychallenge.com – make sure you add me to your contacts so I don’t get spammed.
