I had a chance to solve most of the puzzles before the test. In each of the puzzles, the application of Chess Rules was extremely well applied.
Even for easy puzzles (like Hitori, Minesweeper), one has to apply the Chess rules throughout solving.
I also liked that fact that in most puzzles chess rules led the opening, while in some (i.e. Sudoku) I could start with standard sudoku rules, but the chess pieces placement decided final solution.
