Mini Sudoku glossary
Terms for 6×6 Sudoku with 2×3 blocks on ProPuz.
6×6 grid: Thirty-six cells arranged in six rows and six columns; digits used are 1–6 only.
2×3 block (box): A rectangular region, two rows by three columns, outlined with bold borders. Each block must contain 1–6 once.
Row / column: A full line of six cells; each must contain 1–6 once.
Given: A clue printed at the start; you cannot change it.
Candidate: A small “pencil” note marking a possible digit for an empty cell.
House / unit: Any row, column, or block — a set where digits cannot repeat.
Single (naked single): A cell with only one possible digit left after elimination.
Hidden single: In one house, a digit can appear in only one cell (even if that cell has other candidates on your notes).
Pair / triple: Two or three cells in one house sharing the same subset of candidates; eliminates those digits elsewhere in the house.
Unique solution: Exactly one complete grid satisfies all clues — all ProPuz Mini Sudoku puzzles are built that way.
Difficulty: Controlled by how many givens remain; see the difficulty guide.
