You are looking through a small hole at a corner of a standard six-sided playing die, as shown above. (The picture is showing that there are spots in the corners that you see. It does not imply absence of any other spots.)
Determine at least one of the faces of the die that you are seeing.
5 of the possible 6 faces have corner pips, and 4 of those 5 are paired on OPPOSITE sides of the die, and so cannot be at the same corner. The odd-man-out of the corner-pip club - the one spot - is the ONLY face that can't be there, and therefore its partner MUST be. (Assuming standard die geography of opposite sides must always add to seven.)
