Can't see 264 working either. Or 241.

Oh, hang on.....


...damn - screwed up.


Mick, how did you get your answer? I mean, I think it's right, but I also think I set it up wrong. And if I did, it can't be right.

In the right-hand figure, the top bar should be red, and the bottom right upright should be black.

That makes things different, then, doesn't it? Actually I see the 792 now. But I guess it does depend on whether you are going to require 6 of 7 bars for a 9 or 6, or just 5 bars. My first guess 261 was based on using 5 bars, but then I checked my microwave and saw it uses 6 bars for 9's and 6's. But then again, you could say it doesn't have to be perfect in this case, as it isn't a terribly important issue.

Anyway ... my eyes have been opened. My new answer is 742. No - 772! my Final answer. Did I get it right?

Yep 772 is what I'm going with - oh and on second thought, I think your change doesn't affect the answer, if I understand it correctly - and if 6's and 9's both use 6 bars.

I turned my head upside down (relative to the screen) just now, and 792 works. (9 having five bars)

Here's an image from the first page of results after searching google images for "digital clock" (from my computer):



Not every image includes a clock showing the number 9, but still, it is notable that in the next 9 pages of results, I found no other examples of a 9 made from only 5 bars. The six-bar version is a favorite by more than 10 to 1, I'd say. Either kind would work, though, if schoolboy Mark had to display the number he heard on the phone.

[MarkBastable]

So, with my correction of my stupid error, 266 gives you 792, using the 5-bar 9 and 6.

Prendrelemick wins!

[prendrelemick]

No, I think you win Nicolaii because I'm just confused, we'll call the Fizz question a tie breaker. So your go

Okay - this regards card counting in Blackjack and the problem is from "Blackjack Dealer Error" by ETFan...

...
But whatever dealer you choose, if you sit there for thirty minutes and don't observe a single error in any player's favor, you're at the wrong table. Professorial types may be surprised to learn this factor is even more important than penetration.

If you're in an unfamiliar casino, you may be wondering just how to tell whether a dealer has been working there for three months or three years. There's a less obvious way to ask besides just coming out with "How long have you worked here?" (although there's no law against asking it like that). However, it involves telling a little white lie. I'll leave it to you to figure out, and to decide whether white lies fall within your moral calculus.

I would say - Ey up Ralph, how are you? How long has it been? Must be three years, 'cause that was the last time I was in here!

[togre]

I think something like that would work, but knowing this is a riddle I suspect that might be too simple or vague. If not, I'll be mad that I didn't suggest it

[NikolaiI]

Good guess, but not quite.

[MarkBastable]

I'm getting nowhere with this. Would it help to know why you'd want to know?

[Scheherazade]

Introduce yourself as a company director and claim people will receive bonuses depending on their time with the casino?

[MarkBastable]

I'd be amazed if there were not a corporate edict against directors playing in their own casino.

[cafolini]

I'd be amazed if there were not a corporate edict against directors playing in their own casino.

It's even tacit.
