The objective of a round
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. An attractive position is not enough unless the goal is met. Return to the instructions when a step is unclear.
From the start of a round
- 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.
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. A careful first action helps you become familiar with the layout. Check any mode label before starting.
A useful example
On one puzzle in this collection, row 1, column 1 has D 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. Consider the next action carefully.
Notice this detail
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. After a move, check what changed. Decide which rule explains the new state before acting again.
