Free games like Sudoku — to play every day
The short answer
duplixo has Sudoku itself — free, in four difficulties — plus a whole desk of pure-logic daily puzzles that scratch the same one-solution, no-guessing itch: Queens, Zip, Tango, Pips and Patches, and the number classic 2048. All free, all no sign-up. Here is the lineup, closest first.
What makes a good Sudoku alternative
Sudoku’s appeal is deceptively simple: a grid, a handful of rules, and the quiet certainty that pure logic — never luck — will get you home. A real alternative has to honour that contract, not just look like a grid of numbers. Three things matter.
Exactly one solution, reachable by deduction. The whole pleasure is that there is always a next logical step and never a need to guess. A puzzle that forces a coin-flip has broken the promise.
Rules you can hold in your head. Sudoku needs no vocabulary and no trivia — just a couple of constraints and your full attention. The best alternatives keep that same low barrier and high ceiling.
Free, with no sign-up, and a difficulty to match your mood. No account, no app, and ideally a way to pick your challenge — or a fresh board whenever you want one.
Start with Sudoku itself
Sudoku is on the desk, free and complete: fill the 9×9 grid so every row, column and 3×3 box holds the digits 1 to 9, each once. duplixo’s version runs in four difficulties — easy, medium, hard and expert — with pencil-mark notes, undo, hints, mistake and time tracking, and a guarantee that every board has exactly one solution. Your best time per level is saved on your device, and there is no account and no app. Play Sudoku free — it is the natural home base before you branch out.
Five daily logic puzzles for Sudoku fans
If what you love about Sudoku is the deduction rather than the digits, these five deliver the identical feeling — one board a day, one solution, reasoned out with no guessing.
Queens is the closest of all: an 8×8 grid where you place one crown per row, column and colour region, with none touching. Like Sudoku it is solved purely by constraint and elimination — spot the region that forces a crown, and the no-touch rule cascades from there. Play Queens or read the how-to-play guide.
Tango fills a 6×6 grid with two symbols so each row and column holds three of each, never three alike in a row, honouring the =and× clues between cells. It is the most Sudoku-like fill-the-grid balance puzzle on the desk. Play Tango or learn it in the how-to-play guide.
Zip hands you a numbered grid and asks for one unbroken path that visits every cell once and hits the numbers in order — the same “every square must be accounted for” discipline as Sudoku, drawn as a line. Play Zip or see the how-to-play guide.
Pips, the New York Times domino puzzle, has you lay dominoes so every outlined region meets its rule — a target sum, all-equal, all-different, or a comparison sign. It brings a light touch of arithmetic to the Sudoku-style constraint solve. Play Pips or read the how-to-play guide.
Patches is a shape-fitting puzzle: place a tray of coloured pieces so they tile the board exactly, no gaps and no overlaps. It swaps numbers for polyominoes but keeps the same one-right-arrangement satisfaction. Play Patches or learn it in the how-to-play guide.
A number classic for the in-between moments
2048 is the evergreen number game to reach for when you do not want to wait for a daily. Slide the board so matching tiles merge and double — 2, 4, 8, all the way to the 2048 tile and beyond. It trades Sudoku’s deliberate deduction for quick, planning-ahead moves, but it shares the tidy, one-more-go addictiveness, and there is no daily limit. Play 2048 free.
How duplixo is different
Sudoku and 2048 are public-domain classics. Pips is a New York Times puzzle; Queens, Zip, Tango and Patches are LinkedIn games; those names are used only to describe how each game plays. duplixo’s versions are independent, built from original code, and duplixo is not affiliated with, endorsed by, or sponsored by The New York Times Company or LinkedIn.
Games like Sudoku FAQ

For a number game with the same tidy loop, play 2048. All are free and need no sign-up.
Which game is most like Sudoku?
Queens is the closest in spirit: like Sudoku it is a single grid with one valid solution, solved by constraint and elimination rather than luck. Tango is next — a fill-the-grid balance puzzle — and every logic game here shares Sudoku’s promise that careful deduction always gets you there.
