Swudoku

Swap + Sudoku. One shared puzzle every day. No timer, no guessing. Chase double swaps, aim for a GOAT score, and share with friends.

Swudoku = Swap + Sudoku.

It's the daily logic puzzle that takes everything satisfying about sudoku and gives it a fresh twist: instead of filling in empty cells, you swap tiles to untangle a scrambled board.

Every day, one new 9×9 puzzle drops. The same puzzle for every player in the world. No pencil. No guessing. No timer. Just you, a jumbled grid, and one deeply satisfying goal: solve it in as few swaps as possible.

Think of it as the sudoku equivalent of Wordle: one puzzle, one community, one daily moment of quiet brilliance.

HOW IT WORKS • Tap two tiles to swap them — the board is always full, nothing to type • Read the colours: grey tiles need moving, yellow means correct position, green means its part of complete row, column, and 3x3 block • Hunt for double swaps — moves that correctly position two tiles at once • Share your score when you're done

STRATEGY, NOT SPEED Chess isn't a race. Swudoku isn't either. There is no countdown and no pressure. Your score is your swap count — lower is better. The best solvers read the board first, swap with purpose, and chase GOAT-level scores.

BUILT FOR TOUCH Swapping feels natural on iPhone and iPad. Clean, intuitive gameplay designed for the devices you actually use every day.

YOUR DAILY BRAIN WARM-UP A calm 3–5 minute logic ritual that builds pattern recognition, focus, and that lovely "I solved something today" feeling. Perfect for sudoku fans, Wordle lovers, and anyone who wants something "like a daily crossword, but number-y."
