Free sudoku guide, zero ads.", "siteRuleslastRemainingCellTitle": "Last Remaining Cell", "siteRuleslastRemainingCellIntro": "The Last Remaining Cell strategy flips the sudoku solving perspective: instead of asking which digit a cell can hold, you ask which cell a digit can go into. When only one cell in a row, column or box is capable of receiving a particular digit — because all other empty cells are blocked by that digit appearing elsewhere — the digit is forced into that single remaining cell.", "siteRuleslastRemainingCellSection1Heading": "What is Last Remaining Cell?", "siteRuleslastRemainingCellSection1P1": "Pick any digit from 1 to 9 and examine a specific house — a row, column or 3×3 box — where the digit is still missing. For each empty cell in that house, check whether the digit already appears in the same row, column or box that the cell belongs to. If it does, that cell is forbidden. When every cell except one is ruled out, the sole remaining cell must hold the digit. This is not an assumption — it is a logical necessity of the sudoku grid.", "siteRuleslastRemainingCellSection2Heading": "Finding the cell", "siteRuleslastRemainingCellSection2P1": "Start by scanning the entire sudoku board for a digit that has already been placed many times — digits like 2, 3 or 5 that appear in several boxes. For each house where the digit is missing, mentally block off rows, columns and boxes that already contain it. The remaining intersection is your candidate cell. This technique pairs naturally with the Last Free Cell method: a digit placed in one house often creates a last remaining cell in a neighboring house. Advanced sudoku solvers use this strategy to break open sections of the puzzle that appear stuck.", "siteRuleslastRemainingCellSection3Heading": "Combine with scanning", "siteRuleslastRemainingCellSection3P1": "The Last Remaining Cell strategy is rarely used in isolation. Most experienced sudoku players alternate between scanning for last free cells and hunting for last remaining cells in a single pass over the board. As the puzzle progresses and more digits are placed, the technique becomes easier to apply because fewer cells remain ambiguous. Together with notes, pairs and singles, this strategy forms the backbone of sudoku solving at the medium and hard difficulty levels. The more you practice it, the faster you will recognize the visual pattern of a digit locked into a single position, which is key to tackling expert sudoku puzzles.", "siteRuleslastRemainingCellBackToRules": "← Back to Sudoku Rules", "siteRuleslastPossibleNumberMetaTitle": "Last Possible Number — Basic Sudoku Technique | Sudoked.com", "siteRuleslastPossibleNumberMetaDescription": "Learn the Last Possible Number sudoku technique: examine a single cell and eliminate digits already used in its row, column and box.

Finally, look at the digits in its 3×3 box — those too are excluded. Whatever digit from 1 to 9 is not among those three groups is a candidate.

Cells in the center of the grid, where rows, columns and boxes overlap with many placed digits, are prime candidates. The method also pairs well with pencil notes: after auto-filling all candidates on your sudoku board, any cell showing a single candidate is a last possible number.

You can erase those digits from the notes of every other cell in the row. The same logic applies to columns and 3×3 boxes. This elimination often reduces several cells from three or four candidates down to one or two — immediately revealing naked singles or creating new naked pairs.", "siteRulesnakedPairsSection2Heading": "Eliminate candidates", "siteRulesnakedPairsSection2P1": "The key to spotting naked pairs on a sudoku board is having complete and accurate notes. Scan each house — row, column and box — and look for any two cells that display exactly the same two-digit candidate pattern. Once found, cross out those two digits from all other cells in that house. Do not be tempted to guess which cell gets which digit; the elimination alone is powerful enough.

This leads to naked triplets, naked quads and even larger patterns. While naked pairs are common at the medium and hard sudoku levels, triplets and quads become essential at the expert and master difficulties. The discipline of keeping clean notes and systematically scanning for paired candidates is a habit that serves sudoku players from their first easy puzzle all the way to expert speed-solving.
