Sudoku

Game Guide

Overview

Sudoku is built for quick attempts around a simple loop: Fill the 9x9 grid so every row, column, and 3x3 box contains digits 1-9. First cue: Click an empty cell to select it. Second cue: Type a number 1-9 or click the number pad. A useful replay shows what improved, not just whether the number went up.

Controls

Control cue: Conflicting numbers are highlighted in red. Let the game confirm the result before stacking another action on top, especially when the screen is crowded.

Scoring and Progress

Scoring cue: Press Delete or 0 to clear a cell. A higher number is not the only goal; the better question is which cue arrived late and how the next run will handle it.

Strategy Tips

Practice rule: Look for rows or columns missing only one number. Review one mistake, adjust one behavior, and avoid changing the control style at the same time.

Mobile Play

Mobile cue: Check 3x3 boxes for easy eliminations. Keep the thumb out of the center, use predictable movement, and judge one correction after restart: Use the difficulty button to change puzzle hardness. When a run feels messy, simplify it to Click an empty cell to select it first and Type a number 1-9 or click the number pad second. That order gives the next attempt a measurable purpose. Sudoku review note: click an empty cell to select it should lead into type a number 1-9 or click the number pad. On the next attempt, judge conflicting numbers are highlighted in red against the previous mistake before changing anything else. For Sudoku, use a compact checklist before the next attempt: first cue is click an empty cell to select it, second cue is type a number 1-9 or click the number pad, control cue is conflicting numbers are highlighted in red, and score cue is press Delete or 0 to clear a cell. Sudoku note stays tied to press Delete or 0 to clear a cell, then adjust the earliest visible cue and leave the rest unchanged for one run.
