About This Game

A little space for clear thinking

Hi Sudoku brings classic 9×9 Sudoku to a quiet, uncluttered board. Start with an approachable puzzle or take on a tougher challenge across five difficulty levels, from Beginner to Expert.

Find your own way through

Work through fixed stages or choose a puzzle in free play. Keep pencil marks, highlight related cells and matching numbers, and undo a move when you want to rethink it. Your local progress is saved so you can return to an unfinished puzzle.

Understand the next step

When you get stuck, ask for a hint. Read the explanation and follow the highlighted cells through a logical step, then choose whether to apply the conclusion. Hints are there when you want a little help.

Make yourself comfortable

Choose Paper, Midnight, Sakura or Redline, switch between English and Simplified Chinese, and show or hide the timer. There is no countdown pushing you to finish.
