Puzzle: two cubes


You are given two white cubes. You are asked to draw a digit (from 0..9) on every square of these cubes, such that you will be able to represent evert day in a month using these cubes in certain position. For example, “13” would require that a face on one cube will contain “1” and another face on the other cube will contain “3”.

    Have 0,1,2,3,4,5 on cube 1

    Have 0,1,2,6,7,8 on cube 2

    (6 doubles as 9 upside down)

    I think that works?

    Yes, that’s correct (this was an easy one, isn’t it? 🙂

  3. I was thinking that it would be easier to just represent the month as base-6, giving 35 possibilities. I guess that violates the puzzle criteria? You didn’t say it had to be base 10…

    I just assumed, since you didn’t say otherwise, that single-digit days would only require one cube. In that case you don’t need to do any upside-down tricks:

    0, 1, 2, 4, 5, 6

    1, 2, 3, 7, 8, 9
