The Best Free Sudoku Apps in 2026
Sudoku a Day Blog
There are hundreds of Sudoku apps. Most are cluttered with ads, paywalls, or annoying features you never asked for. Here are the best free ones in 2026.
Sudoku a Day (That Is Us)
We might be biased, but we think we offer something special: a clean, ad-free experience with daily puzzles at every difficulty level. No account required, no subscriptions, no distractions.
You get one new puzzle every day in Easy, Medium, Hard, Expert, and Master. Track your streak. Print PDFs. All free.
What Makes a Good Free Sudoku App?
Before we list others, here is what matters:
1. No ads. Ads interrupt flow and ruin the experience.
2. No paywalls for daily puzzles. If I have to pay to get today's puzzle, it is not a daily Sudoku app—it is a paid puzzle app.
3. Clean interface. No clutter, no gamification overkill, no pop-ups.
4. Multiple difficulties. Easy to Master, all included.
The Others
Other solid options include Simple Sudoku (clean, no-frills), Sudoku.com (widely popular, ad-supported free tier), and Andoku (open-source, no ads).
But honestly? Most free versions are ad-heavy or limited. We built Sudoku a Day because we wanted something different: a daily puzzle, always free, always clean.
The Bottom Line
If you want a free Sudoku app without the noise, try ours. One puzzle every day, no strings attached.
