Understand the basics of 6x6 Sudoku

Give this approach a try

Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Refer to the controls when needed.

The objective of a round

Fill all cells with 1–6; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Check the rules when you are unsure.

How to proceed

  1. Select an empty cell. The original clues cannot be edited.
  2. Choose a symbol from the number pad, or type it on a keyboard.
  3. Turn Notes on to record candidate symbols without committing an answer.
  4. Use Check entries to check your filled values. Hint reveals one value from the verified solution.
  5. Complete the board, or choose New puzzle for another board.

How to use the controls

Tap or click a cell and use the number pad. Keyboard: arrows select cells; digits (and A–G on 16×16) enter values; Backspace erases. Keep the playing area visible while using these controls. Check any mode label before starting.

Learn from a sample situation

On one puzzle in this collection, row 1, column 2 has 4 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Compare this with the rule that governs the move. Look for the relevant detail.

Watch out for this

Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Take a moment to reassess the position before continuing. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
