Endless Sudoku provides you with a virtually limitless collection of Sudoku puzzles.

You'll always have a fresh challenge. * Unlimited computer-generated puzzles provide a unique challenge for seasoned solvers * 4 difficulty levels * Squeaky clean interface * Optimized for devices of all sizes * Free forever! (but if you want to get rid of some loose change and pay to remove the ads, that's also cool) ## Key features - Unlimited computer-generated puzzles - Four difficulty levels - Squeaky clean interface - Optimized for all devices - Free to play ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Remove Ads | $0.99 | one-time | ## Recent user reviews (9 of 9) All indexed reviews: https://appshunter.io/ios/app/endless-sudoku/id492773309/reviews.md ### 5/5 — Great game *2022-10-20, version 2.1.5* Great game? ### 5/5 — Sudoku *2017-09-24, version 2.1.2* Best available... ### 5/5 — Sudoku sadness *2015-03-05* What have you done? I got an update today and the new version is terrible. Until now it was my favourite game and has been for a couple of years. Please fix it. 😪 **Developer response:** What seems to be the trouble? The newest update adds support for newer devices, and fixes a number of long standing bugs. ### 1/5 — Sudoku *2013-10-09* Problems I've encountered when comparing this to other apps: 1. No ability to pencil in the possible numbers in a box 2. Numbers annoyingly at bottom of the page 3. Most difficult puzzles are still too easy Needs some work before it compares to other apps. ### 5/5 — Very nice! *2012-12-29, version 1.3* I am not a power sudoku player, but I like this version. It's clean looking and easy to use. If I had any complaint it would be that the number selections are really close to the ads which makes it easy to accidentally tap the ad. But I just need to be more precise in my taps I guess. Overall I give it five stars and recommend it! ### 5/5 — Good app. *2012-05-23, version 1.1* Sleek look and a nice interface. I like it a lot! ### 1/5 — Not up to par *2012-04-08, version 1.1* This game gets frustrating when u go to hit a number and it produces a new game without asking if u really wanted to quit ### 2/5 — Sudoku *2012-03-24, version 1.1* This app had only one review. So now it has two. It has symmetrical puzzles, which is good. It has a nice interface, which is good. It has NO pencil marks, which is NOT NOT NOT good. Nuff said. ### 5/5 — Good sudoku app *2012-02-15, version 1.1* Well since none has reviewed this app yet, I might as well review this anyway. This is a really good app that I find worth it.(got it at what's featured in the app store 2 weeks ago) It's great that it has 4 difficulties that can help you get better at sudoku ranging from easy to hard. Well anyways, great app! ## Frequently asked questions about Endless Sudoku ### How many puzzles does Endless Sudoku have?
