How to play
- Fill every cell with a digit from 1 to 6.
- Every row, column and box holds each digit exactly once. Boxes are 3 cells wide and 2 tall.
- The shaded digits are givens: they’re locked in.
Controls are the same as classic Sudoku: tap a cell, then a digit; Pencil (or N) for marks; Fill candidates does the bookkeeping for free. Hints (3 per puzzle) name the technique, explain it and fill the digit. Easy boards need singles, Medium a Naked Pair, Hard a Pointing Pair.
New to the techniques? The Learn track teaches all five on classic 9×9; they work exactly the same here. Ready for the full size? Classic Sudoku →
