The challenge in front of you
Fill all cells with 1–9 and A–G; do not repeat a symbol in any row, column or region. Keep that objective in view throughout the round. Return to the instructions when a step is unclear.

- 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.
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. Keep the playing area visible while using these controls. Read the example below alongside these instructions.
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. Notice the change in the playing area.
Check this before moving on
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. 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.
