Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Refer to the controls when needed.
Your goal
Complete five overlapping Sudoku boards. Every shared cell must satisfy both boards that use it. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
Step by step
- Select an editable cell.
- Enter a value using the keypad or keyboard; Notes stores candidates.
- Read the region, cage, arrow or outside clues alongside the normal constraints.
- Check entries verifies the completed board; Undo reverses your last input.
- New puzzle selects another included puzzle.
Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. On a smaller screen, keep the active part of the board within view. Use one clear input at a time.
A useful example
One value entered in an overlap serves two boards, so check the corresponding rows, columns and boxes of both. Focus on why the action is allowed, not only its outcome. Take a moment to compare.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
