Developing Systematic Thinking
At medium difficulty, 6x6 puzzles require students to use elimination more deliberately. When a row has four of six numbers filled, the remaining two cells can only contain the two missing numbers. Determining which goes where requires checking both the column and the box constraints — a three-way intersection check that is the fundamental operation of all sudoku solving.
