$476 million Mega Millions jackpot

Well, let's compare.

UK's national lotto has you pick 6 (technically 7, but that seventh only applies if you get 5 of 6) out of 49, for odds of 13,983,816 to 1.

To win MegaMillions, you have to pick correct on both a 5 out of 56 draw and a 1 out of 46 draw, for odds of 175,711,536 to 1.

The odds are worse by a factor of 10, and from looking at both of their payout tables, the National Lottery is actually a lot more generous in terms of winning any sort of prize, as well.

They cap the number of times the jackpot can roll over, though, whereas MegaMillions (like PowerBall) increases the jackpot until there's a winner. It starts at $12 million, though, so it takes a while to hit these mind numbers, hence why people get excited every time it happens.

Jam it back in, in the dark.
