Sudoku Blast Alternatives Without Ads or Subscriptions

Sudoku Blast sells itself as "5-min sudoku": short, clean games with hints, notes and a daily puzzle. Its App Store age rating notes advertising, and every paid item its listing shows is a subscription. If you want the same quick games without ads or a recurring charge, Sudoku Royale has no ads and nothing to buy, Sudoku by Mind The Frog drops its ads for one small payment, and Sudoku by MobilityWare+ is ad-free for Apple Arcade members. If quick has started to mean too easy, Good Sudoku and Sudoku Royale both go much harder.

Sudoku Blast is not a bad app. It has 76,426 US ratings since 2022, and players clearly like the feel of it. Most people looking for an alternative have one of three reasons: the ads, the subscription, or puzzles that no longer stretch them. This page is organized around those reasons.

Pick by the reason you are leaving

If it is the ads and the subscription

Sudoku Blast's listing does not say what its subscriptions unlock, so check the purchase screen before you subscribe. Either way, there are three ways to play without ads that do not involve a recurring sudoku bill.

Sudoku Royale (our app) has no ads, no purchases and no subscription. Unlimited Practice puzzles, the Daily Challenge and the lessons are all free from the first launch, without an account. The catch is how it plays: there is no undo, and every number is checked the moment you place it, with a wrong one rejected. Some players like never building on a mistake; others miss being able to test an idea and take it back.

Sudoku by Mind The Frog is the one-payment option. Its listing promises a small app with no long intros or slow animations, undo and redo, automatic and manual notes, and up to ten grids in progress at once, on or offline. Ads go with a $1.99 Remove Ads purchase.

Sudoku by MobilityWare+ costs nothing extra if you already have Apple Arcade (Apple Arcade subscription, no ads). It starts on smaller, colored grids and has weekly events; a classic black and white board is in the play menu.

If you want short games that stay short

The appeal of Sudoku Blast is a puzzle you can finish on a coffee break. Any app can do that at its easy levels, but two things help. In Sudoku Royale's Practice mode there is no countdown and no mistake limit, so a five-minute Easy or Medium game stays relaxed; a timer shows in the corner and cannot be hidden, which bothers some players. Input is quick too: you can tap a cell and pick a number, arm a number and tap cells, or use slide-to-select on the grid. Mind The Frog's ten saved grids suit a different habit: start a puzzle on the bus, leave it, pick up another one later.

If the puzzles have stopped being a challenge

Sudoku Blast's listing describes an "easy-to-advanced difficulty progression" without naming its levels or the solving techniques they need. If you finish its hardest puzzles without stalling, move to an app that says what is above that.

Good Sudoku is the furthest step up. Its listing says its hardest puzzles need techniques like XYZ-Wings, Jellyfish and Swordfish, and its hints read your notes to find the technique you are missing. The full game is a one-time $4.99 unlock.

Sudoku Royale has six levels, Easy to Extreme, and the top two unlock after a few solves at the level below. When you get stuck in Practice, the hint names the technique and the cell instead of the answer and links to the lesson. The Journey teaches one technique per chapter over 88 levels, ending with patterns like the X-Wing and XY-Wing. For a direct feature comparison, see Sudoku Royale vs Good Sudoku.

If you want more from the daily puzzle

Sudoku Blast lists daily challenges with fresh puzzles. Sudoku Royale's Daily Challenge adds a streak with your best run, a leaderboard against friends and the world, and an archive of past days, so a missed day is not lost. Good Sudoku has three daily modes that get harder through the week, with global leaderboards.

When Sudoku Blast is still the better pick

• You do not mind ads. Then it is a well-rated, simple app and there is no strong reason to move.
• You want the app in your language. Its listing shows 41 languages. Sudoku Royale's app is in English only.
• You often play without a connection. Sudoku Royale's Practice works offline with puzzles it has already downloaded, but hints and the Daily Challenge need the internet. Our offline sudoku guide covers apps that work fully offline.
• You rely on undo. Sudoku Royale has none.

The short version

Pay nothing and see no ads: get Sudoku Royale. Pay once and keep undo: Mind The Frog. Already on Arcade: MobilityWare+. Want much harder puzzles: Good Sudoku. The head-to-head is in Sudoku Royale vs Sudoku Blast, apps that charge once are in sudoku apps without a subscription, and every other matchup is on the comparisons hub.
