Pandigital Squares by Oyler

Posted by Listen With Others on 17 Jun 2010

Ten double sided cards each have a different single digit printed on each side. When the cards are arranged in a row a pandigital square, P, is formed. When the cards are turned over and kept in the same order the result is a different pandigital square Q. In the clues the subscripts refer to the cards in positions 1 to 10 respectively. For example if P was 6154873209 then P25 would be the four digit string 1548. In order for solvers to identify P and Q, the grid, which has 180° rotational symmetry, should be completed. In the grid no entry starts with zero and all are different. P and Q should be written underneath the grid.


Across Down
1 P13 + P89 1 P3 x P6
3 P10 x P10 = Q12 2 Q10 x Q34
5 Q47 3 Q8 x Q23
7 Q3 x Q4 x Q5 4 P6 (P7 + P8)
8 P4 (Q12 – P12 ) / Q9 6 P46 + Q46 + P34 + Q67
9 P36 7 P24 + Q68 – Q10
12 P2 x P7 8 Q10 x Q12
13 P79 10 Q4 x Q4 = Q34
11 P1 x P2 x P3 x P4
