Play 4x4 Sudoku with the rules at hand
Use a short break to learn the rhythm of 4x4 Sudoku. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Choose a clear next step rather than rushing through the instructions. Keep the instructions close while learning this activity. Check the relevant rule before repeating a move.
An idea for your next attempt
After a move, check what changed. Decide which rule explains the new state before acting again. Notice the feedback after each input.
The goal to keep in mind
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. The example below illustrates a decision.
Follow these playing steps
- Select an empty cell. The original clues cannot be edited.
- Choose a symbol from the number pad, or type it on a keyboard.
- Turn Notes on to record candidate symbols without committing an answer.
- Use Check entries to check your filled values. Hint reveals one value from the verified solution.
- Complete the board, or choose New puzzle for another board.
Using the playing area
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. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.
A useful example
On one puzzle in this collection, row 1, column 2 has 2 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Use the example as a guide rather than a substitute for reading your board. Verify the rule before continuing.
Watch out for this
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
