Sweet Sudoku

Fill the 9×9 grid so every row, column and 3×3 box holds the digits 1 to 9 once. Select a cell and tap a number, or use the arrow keys and type 1–9. Switch on pencil notes (N) to jot candidates; they clear themselves as you place digits. A wrong digit is never placed and costs a tenth of the score; stuck, tap the bulb twice to reveal a cell for two tenths. Practice at easy, medium or hard (hard needs X-wings and triples), or climb the level ladder, where every tenth level pays a candy bonus. Every puzzle has exactly one solution and never needs a guess, and the daily sudoku is the same medium puzzle for everyone, so you can rank on the leaderboard or send a friend the same grid.

1. Click a cell (or move with the arrow keys) and type 1–9, or click the number pad.
2. Press N (or the ✎ key) for pencil notes; Shift+digit notes one too. Backspace clears notes.
3. Fill every row, column and 3×3 box with 1–9. A wrong digit isn't placed and cracks one of nine sweets (a tenth of the score each), but you keep going until the grid is solved.
4. Stuck? Tap 💡 (or H) twice to reveal a cell: it costs two sweets. Pick Easy, Medium or Hard for practice, or climb the levels: every 10th pays a candy bonus.
