Word Sudoku Generator

Turn any 9 words, symbols or emoji into a print-ready Sudoku - ideal for vocab, music notation, Christmas symbols or any topic. Includes answer key.

Paste in any 9 words, phrases, symbols or emoji, and this tool instantly builds a complete Sudoku puzzle using them in place of the numbers 1–9 — then generates a polished, ready-to-print worksheet.

Works for any subject.
Modern Foreign Languages: vocabulary, tenses, key phrases
Music: notation, dynamics, tempo markings — even music symbol fonts render beautifully
Seasonal: Christmas, Easter, or topic-themed emoji puzzles
Any subject with 9 key terms, symbols or images pupils need to learn

Built for the classroom, not number-scanning
Word Sudokus are naturally harder to solve than number Sudokus, since pupils can’t pattern-scan digits — so puzzles are generated at Very Easy or Easy difficulty, keeping the focus on vocabulary recall rather than logic-puzzle difficulty.

Two worksheet styles
Square grid — the classic Sudoku look
Relaxed Fit — a wider landscape layout with larger, more legible text and generous space in every cell for pupils to write their answers by hand. Great for accessibility and younger pupils.

Every worksheet includes
An editable title, so you can rename it for each class or topic
The puzzle grid with a word bank reference underneath
A second page with the full answer key, automatically generated

Play on screen or print
Pupils can solve the puzzle interactively in the browser (click a cell, then click a word to fill it in), check their answers, reveal the solution, or generate a brand new puzzle from the same 9 words for extra practice.

Simple and safe to use
Runs entirely offline in the browser once opened — no installation, no accounts, no login
Fully GDPR-compliant: no pupil data is ever uploaded or transmitted anywhere
Works across any topic, any language, any symbol set your keyboard (or emoji picker) can produce
