The position of the lowest grid is fixed and marked. There are no holes in the lowest grid.

Round 13 – OLD MAID

Team

This round contains 25 puzzles. There are exactly 12 pairs of puzzles that have the same solutions. The remaining puzzle does not have a matching puzzle. There is only one way to organize the puzzles into 12 pairs and one puzzle which satisfies this condition. Therefore, the points for a puzzle will be awarded only if its solution is a part of this solution. Even if it is possible to pair two puzzles and find a solution for this partial puzzle, it would prevent the rest of the puzzles to be paired up properly, therefore no points will be awarded in such cases.

Sudoku types appearing in this round are as below

A Classic Sudoku ........... 65 points

B Classic Sudoku ........... 25 points

C Classic Sudoku ......... 111 points

D Classic Sudoku ........... 50 points

E Classic Sudoku ........... 35 points
