4x4 Sudoku: learn through an example
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. Keep the instructions close while learning this activity. Keep the game area visible while you use its controls.
Build familiarity through play
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Refer to the controls when needed.
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. Try to explain the aim in your own words.
The order of play
- 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.
Your inputs
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. Look at the feedback after the action.
An example before you play
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. Compare this with the rule that governs the move. Keep the controls nearby.
Watch out for this
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Check the rule before repeating the action. 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.
