I haven't tried this myself but thought it might be an interesting problem.
Given two 6-sided dice, and able to write any (single) number on any face of either dice, what is the largest number you can count up to (ie display each number starting from 1) and how are the numbers arranged on the dice?
Assume you only need to show a single value for numbers less than 10 ie 9 and not 09

If 6 can be turned upside down and used as 9 it is 43. (otherwise 32)

Nice, inverting a 6 would be allowed.
The practical use is that we have a Christmas thing with dice that count the days down to Christmas, and rather than looking to what they have I thought I'd pose the question here instead.

I'm not sure whether I got the question.

> any (single) number

Do you mean cipher by that?

> count up to

That just means: arrange the two dice (being allowed to hide one of them), so that they show a number?

What if, in addition to a 6 being flipped over to make a 9, you could also flip a 7 over to make a 1? In that case, how high could you count?

well while we're at it...a lot of sports teams use the same thing for a '2' and a '5'. Or are we now making it too easy?
