THE PLAYBOOK · SUDAANMO
Getting started with 4x4 Sudoku
Take a moment with 4x4 Sudoku before moving to another game. Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Check the relevant rule before repeating a move. Choose a comfortable screen position before beginning. Look at what changes after your first action.
Practice beyond the first move
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
What counts as success
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Use the instructions to see which actions move you towards it. Return to the instructions when a step is unclear.
The playing sequence
- 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.
Making selections and moves
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. Return to the rules if the result is unexpected.
See how the rules apply
On one puzzle in this collection, row 1, column 3 has 4 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. Choose a deliberate next step.
Pay attention to this rule
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
