**Team**

This round contains 25 puzzles. There are exactly 12 pairs of puzzles which have the same solutions. The remaining puzzle does not have a matching puzzle.

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.
