How to Play Sudoku Unlimited
Sudoku Unlimited deals a fresh 9x9 grid whenever you want one, at the difficulty you pick: easy, medium or hard. Every grid has one solution reachable by logic. Unlimited rounds never repeat today's daily and do not count toward your streak, so they are the place to practise.
How Sudoku works
Sudoku is played on a 9x9 grid divided into nine 3x3 boxes. Some cells arrive filled in; you fill the rest. The goal is a grid where every row, every column and every box holds each digit from 1 to 9 exactly once.
Tap a cell, then a digit on the pad, or type it on a keyboard. Notes turns the same keys into pencil marks for the candidates a cell still has, and placing a digit clears it from the notes of every cell it rules out. A repeated digit outlines the moment it lands.
The daily grid is the same for every player in the world and changes difficulty with the week: easy on Monday and Tuesday, medium from Wednesday to Friday, hard on Saturday and Sunday. In Unlimited you choose the difficulty yourself.
Every grid is solved by a program before it is served. Easy grids need only the first technique below, medium grids the second, and hard grids also need pointing or a pair; none ever needs a guess. Your time goes to the global leaderboard.
How to solve a sudoku
The only digit. Pick an empty cell and list the digits its row, column and box already hold. If eight of the nine are taken, the cell must be the ninth. Easy grids solve with this alone.
The only place. Pick a box and a digit it is missing, then rule out every cell whose row or column already holds that digit. When one cell is left, the digit goes there. Medium grids need this.
Pointing and claiming. If a digit's last places in a box all sit on one row, no other cell of that row can take it; if a row's last places for a digit all sit in one box, the rest of that box cannot. Write the eliminations in your notes.
Pairs. When two cells of a row, column or box can only hold the same two digits, those two digits belong to them, and every other cell of that unit can drop them. Hard grids need pointing or pairs at least once.
Sudoku and Mini Sudoku: what differs
The same rule on two grid sizes. Both are free daily puzzles here.
| Feature | Sudoku | Mini Sudoku |
|---|---|---|
| Grid | 9x9, nine 3x3 boxes | 6x6, six 2x3 boxes |
| Digits | 1 to 9 | 1 to 6 |
| Given cells | 28 to 38, by difficulty | 14 |
| Daily difficulty | Easy to hard through the week | The same every day |
| Techniques needed | Singles; pointing and pairs on hard days | Singles only |
| Typical time | 5 to 25 minutes | 2 to 5 minutes |
Mini Sudoku is the 6x6 daily; both have Unlimited for practice.
Tips & Strategy
Words like CRANE, STARE, or ADIEU test common letters quickly. Knowing which vowels are present narrows options fast.
Green letters stay locked. Yellow letters must move. Gray letters are eliminated. Each guess should use all three clues.
English words often end in -TION, -IGHT, -OUND, -MENT. Other languages have their own patterns — learn them.
Your second word should test new letters, not repeat confirmed ones. Cover as many untested consonants as possible.
Words like CREEK, FLOSS, or APPLE are common traps. If your clues don't add up, consider a repeated letter.
Hard mode forces you to use confirmed clues in every guess. It builds better habits even when you switch back to normal.
