Coincidence?

One of the freakest random events ever seems to have occurred in the Bulgarian national lottery, when the same six winning numbers were selected on two consecutive draws on 6 and 10 September. An investigation has apparently found no evidence of wrong-doing: it was just a remarkable coincidence. I find that hard to believe. What do you think?

Interesting. Warrents investigation but coincidences do happen. It's a memoryless system so each set of numbers is equally likely to come up - including last week's. But however much I know it's a likely as any other combination I still can't, in my core, make myself believe 1, 2, 3, 4, 5, 6 would be a worthwhile gamble were I to play a lottery.

Slightly weird that no one won it one week and then "a record 18 people" won the second week. If you were going to rig it, wouldn't you just do it once and cash in, rather than failing to win the first week? Or at least rig it differently each time? Still, it could be an accidental rigging - slightly heavy balls by mistake. But the investigation apparently says no.

It's odd that 18 people (and that a "record" number) all guessed last week's numbers - they presumably either didn't know what last week's were or didn't share your disbelief in coincidence.

I'm very far from convinced that nothing was wrong. I don't remember hearing of a lottery when 5, 4 or 3 of the previous week's numbers came up next week. Coincidences like this just don't happen.
