A small practice goal
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.
What you are aiming for
Fill all cells with 1–4; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
How a round unfolds
- 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.
Keyboard and screen 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. Read a button’s label before selecting it. Read the example below alongside these instructions.
Follow the 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. Apply the same reasoning to the position in your own round. Read the matching step again.
A mistake to avoid
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. After a move, check what changed. Decide which rule explains the new state before acting again.
