Medium sudoku is the step after easy. With fewer given digits, you sometimes need to find the only place for a number across an entire row, column, or box. Free, no sign-up, a new puzzle in one click.
Medium suits players who can finish easy puzzles confidently and want more logical steps without a sharp jump in difficulty. Every puzzle has a path that can be reasoned through without guessing.
Medium reveals fewer digits than easy. Obvious single candidates are not enough on their own: you need hidden singles, where a digit has only one possible place in a row, column, or box. Pairs and advanced strategies are not required.
Regular play sharpens attention and logic, and gives your mind somewhere quiet to go. Medium gives a steady sense of progress and fits neatly into a short break.
