## What is Digital Sudoku ⊞?

Digital Sudoku is a Sudoku variant with a twist: every clue isn't a printed number, it's a partial seven-segment display, the kind you'd see on an old calculator or digital clock. Some segments are lit, some aren't — read the pattern, decode the digit, and place it. Once you're solving, it's classic Sudoku logic all the way down.

FEATURES

• Three board sizes — 4×4, 6×6, and full 9×9 — each with Easy, Medium, and Hard difficulties (9×9 adds Expert).
• A new Daily puzzle every day, with its own streak to keep going.
• Stuck? Hint walks you through the next logical step instead of just filling in the answer — you still have to place it yourself.
• Undo/redo, a mistake-checking readout, and an optional timer you can show or hide.
• Achievements and stats track your solves, streaks, and best times per board and difficulty.
• Compare your times on a real per-puzzle leaderboard.
• Light and dark themes, both designed around the seven-segment look.
• Play instantly as a guest — no account or sign-up required.

Whether you're decoding your first 4×4 or chasing an Expert 9×9 streak, Digital Sudoku turns a familiar puzzle into something you have to look twice at.
