Word Sudoku (Wordoku) — Interface
This page provides a clean, modern, and interactive Wordoku experience. Here’s a breakdown of what end users see and how each part works:
🎮 Main Components of the Interface
1. Title & Subtitle
At the top, users see:
“Word Sudoku (Wordoku)” — the name of the puzzle.
A short explanation:
“Fill the grid with letters so each row, column, and 3×3 box has all 9 letters. A secret word hides on the diagonal!”
This tells users exactly what makes Wordoku different from traditional number Sudoku: it uses letters and contains a hidden word.
2. Game Information Bar
Right under the title:
Letters: Displays the set of 9 letters used in the puzzle (derived from the hidden 9-letter word).
Hidden Word: Shows “?????????” initially, revealing letters only when users request it.
This section helps solvers track which letters must appear in the puzzle.
3. The 9×9 Puzzle Grid
A visually appealing Sudoku grid with:
9 rows × 9 columns
3×3 sub-boxes separated by thick borders
Some cells pre-filled (shown in gray) — these cannot be changed.
Empty white cells — users fill these with letters.
Interactive features:
Click a cell to select it (highlights in gold).
Type a valid letter or delete it with Backspace/Delete.
Invalid input is ignored (only the nine allowed letters work).
Incorrect entries flash red during solution checking.
4. Control Buttons

🧩 How to Solve Word Sudoku (Wordoku)
Solving Wordoku follows the same logic as number-based Sudoku, but with letters instead of digits.
⭐ Goal
Fill the 9×9 grid so that:
Each row contains all 9 letters exactly once.
Each column contains all 9 letters exactly once.
Each 3×3 box contains all 9 letters exactly once.
The main diagonal (top-left to bottom-right) spells the hidden 9-letter word.
📝 Step-by-Step Solving Strategy
Step 1 — Observe the Given Letters
Look at the filled (gray) cells:
They give you anchors for each row/column.
Since the letter set is only 9 letters total, you know exactly which must appear.
Step 2 — Use the Letter Set
Displayed above the grid:
These 9 letters appear once per row, once per column, once per box.
You can think of them like “1–9” in regular Sudoku.
Step 3 — Fill Obvious Spots First
Look for:
Rows or columns missing only one letter
Boxes where 7 or 8 places are already filled
Letters that only fit in one possible location
Step 4 — Use the Hidden Word Diagonal Constraint
You know the diagonal spells the hidden word (even though the word is not shown):
If you know 2–3 letters from diagonal prefilled cells,
You can often deduce the type of word structure (prefix, suffix, patterns),
This gives clues about what other diagonal cells must be.
Step 5 — Process of Elimination
For each empty cell:
Check the row: Which letters are missing?
Check the column: Which letters are missing?
Check the box: Which letters are missing?
The intersection gives the possible letters.
Often only 1 letter fits.
Step 6 — Use Hints if Necessary
The game gives 3 hints per puzzle.
If a cell is difficult, click it and press Hint to auto-fill the correct letter.
Step 7 — Check Your Solution
When the grid is completely filled:
Hit Check
The game:
Highlights mistakes in red
Shows “Perfect! You solved it!” for correct solutions
Reveals the hidden word
Step 8 — Reveal Word (Optional)
If you’re curious or stuck, press Reveal Word.
