The jackpot has been going on for a long time if I'm not mistaken, more than a year. If no one hits it yet to this day, that could be caused by the self-reporting system, so someone might never realize that they have ever gotten two 77.77 in a row. But because self reporting is part of the rules, we have to respect it and if someone cares enough about such jackpots, then they can use bots when doing automatic roll, like seuntjie bot. That way, they can track their betting history to search for the requested bet id's.
