Every day PuzzleCraft publishes one Sudoku that everyone plays. It sits next to the daily crossword and word search in Today's Puzzles on the home page, and each day's grid gets its own permanent page so you can come back to it.
The difficulty follows the week: Monday is Easy, Tuesday and Wednesday are Medium, Thursday and Friday are Hard, Saturday is Expert, and Sunday is a Hard puzzle to round off the week. Sign in to build a streak, and finish the crossword, word search, Sudoku and jigsaw on the same day to earn toward the Daily Sweep badge (every daily puzzle).
When you finish, share a spoiler-free result card with your time and streak, like “PuzzleCraft Daily Sudoku ✅ 8:14 🔥 5-day streak”. Missed a day? The archive keeps the last 30 days.
How it works: every PuzzleCraft Sudoku is built from scratch by a generator that fills a complete 9×9 grid and then removes numbers one at a time, checking with a solver after every removal that exactly one solution remains. You will never get a puzzle that needs guessing or has two answers.
Difficulty is rated by the solving techniques a puzzle needs, not just by how many numbers are given. Easy puzzles fall to singles alone. Medium adds naked pairs and pointing. Hard needs triples and box/line reduction. Expert asks for advanced patterns such as the X-Wing and XY-Wing.
Stuck? The Hint Assistant teaches instead of just giving answers. The first hint points to the area to look at, the second names the technique, the third highlights the exact squares and explains the logic in plain English, and only the fourth fills in the number. Hints used appear on your results card.
