About game

Sudoku Lite is a focused 9x9 number puzzle with daily and practice sessions. Place digits so each row, column, and 3x3 box uses numbers 1-9 exactly once. You can switch note mode for candidates, clear risky entries, and recover a clean line-by-line solve path.

Objective

Complete the full grid with correct digits while avoiding row, column, and box conflicts. In daily mode, solve within time and mistake goals to keep your streak growing.

Controls

  • Desktop: click a cell, then use number keys or keypad buttons
  • Mobile: tap a cell and enter 1-9 from the on-screen keypad
  • Use Notes to pencil candidates and Erase to clear wrong entries

Rules

  • Each row must contain digits 1-9 once
  • Each column must contain digits 1-9 once
  • Each 3x3 box must contain digits 1-9 once
  • Given cells are fixed and cannot be edited

Tips

  • Scan one unit at a time and place obvious singles first
  • Use notes for two-way and three-way candidate checks
  • When conflicts appear, clear fast and rebuild from confirmed cells

Session

Most sessions take 4-12 minutes depending on difficulty and note usage.
