A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
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. Return to the instructions when a step is unclear.
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. Read the example below alongside these instructions.
A useful example
One value entered in an overlap serves two boards, so check the corresponding rows, columns and boxes of both. Use the example as a guide rather than a substitute for reading your board. Look for the relevant detail.
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
