012345 on one, and 012678 on the other. Good one. I also liked the guys buried in sand problem. Took me a good 15 minutes to see what the "extra information" was. Silence! Very clever.

An upside down 6 is NOT a 9. The answer is cute, but not an answer.

Ok, if you don't accept my solution, what's yours? I still think an invertible 6/9 block is the intended solution.

I think your solution is 100% the intended one. I just think that the problem is a bit weak in that it is font dependant.

I actually knew the answer without thinking as I happen to own two such cubes that were given to me years ago.

I guess it just made me feel a bit smug.

Cheers, Tony
