Getting Started with Sudoku365: Your First Daily Puzzle

Starting a sudoku habit is easier than most people think. You do not need to memorize advanced techniques or block out an hour of your day. You need one grid, a difficulty that fits, and a few minutes. This post walks you through your first days with Sudoku365: what the app is, how to choose a difficulty level, how the daily habit takes shape, and why using hints is nothing to feel bad about.

What Is Sudoku365?

Sudoku365 is a daily sudoku app for iOS and Android with 1200 puzzles across four difficulty levels, from Easy to Expert. It is built around one simple idea: a little sudoku every day trains logic, focus, and problem-solving without demanding much of your schedule.

To support that daily rhythm, the app tracks your streak automatically, so consecutive days of play add up into a record you can see. While you solve, notes, hints, undo, and erase are always at hand, and a mistake check helps you catch small slips before they spoil a grid. Stats show puzzles completed, best time and average time for each difficulty. You can pick a system, light or dark theme, and solo play works offline, so the puzzles come with you even when a connection does not.

The game is free with ads. A one-time Remove Ads purchase (¥300 in Japan) turns off the banner and interstitial ads. There is no subscription.

Picking Your Difficulty

Sudoku365 offers four difficulty levels, and my honest advice for a new player is to start lower than your pride suggests.

• New to sudoku entirely? Start at Easy. The point of your first grids is to learn the rhythm of the game, with rows, columns, and boxes each needing the digits one through nine, not to struggle.
• Played before, but casually? Easy or the next level up is still a good warm-up. A few comfortable solves will tell you quickly whether to move on.
• Experienced solver? Jump in wherever feels right. With four levels up to Expert, there is room to climb, and 1200 puzzles means you will not run out of grids at any level soon.

There is no penalty for choosing a gentler level. A puzzle you finish teaches you more than a puzzle you abandon, and you can change difficulty whenever you like.

Building the Daily Habit

The “daily” in daily sudoku is where the real value lives. One grid a day is a small commitment, but it compounds: your scanning gets faster, your deductions get sharper, and the game starts to feel less like effort and more like a pause in the day.

Sudoku365 tracks your daily streak automatically, which gives the habit a visible shape. Day three becomes day four becomes day ten, and at some point protecting that number becomes its own quiet motivation. A suggestion that works for many people: attach the puzzle to something you already do daily, such as morning coffee, the commute, or the last minutes before bed, so the habit has a home rather than floating loose in your schedule.

The Daily Challenge, Reminders and a Second Player

Besides the puzzles you pick yourself, the home screen has a Daily Challenge: one new puzzle a day, the same for everyone. You can play it once per day. On iOS your time goes to a Game Center world ranking. The Android version has the Daily Challenge but no ranking.

If you tend to forget, turn on reminders in Settings. You choose the days and a time for each. And if you do miss a day, the week strip on the home screen lets you make it up: tap a missed day from the past six days, watch an ad, and solve that day’s challenge to fill it in.

When someone with a phone is sitting next to you, try Play Together. Race gives you both the same puzzle, and the first to finish wins. Solve together puts two people on one board, with shared mistakes and hints. One person creates a room, the other joins it, and the phones connect over Bluetooth. It works between iPhone and Android, and no internet or account is needed.

Using Hints Without Guilt

Some players treat hints as cheating. I would gently push back on that. A hint that gets you unstuck is a teaching moment: look at what it revealed, then work backwards to see the logic you missed. That is how techniques move from things you read about to things you notice.

Hints also protect the habit itself. A grid that feels unsolvable and ends in frustration makes tomorrow’s puzzle less likely to happen. A hint that keeps the solve moving keeps the streak intact, and your enjoyment with it. The same goes for the mistake check: catching an error early is not a failure, it is how you avoid unwinding twenty minutes of work. Use the tools. They are there for exactly this. You start with 10 hints, get one more each time you clear a puzzle, and can add one by watching an ad from the Store screen.
