Best Game to Reinforce My Abilities to Identify Numbers Effected By My Dyslexia!!!I have various sets of individual digits which are part of the numbers repeatedly effected by my dyslexia which are not just a struggle but increase my overall anxiety level and cause me to repeat number operations to the point where my anxiety has progressed past stressed-out and into other types of anxiety such as OCD-Obsessive-Compulsive-Disorder-&-Generalized-Anxiety which requires me to remain away from the stress of interactions with other people and can become a very isolating condition!!! I discovered that by including Sudoku in my everyday start-up or daytime routine, then my anxiety levels decrease by sharpening my skills with proper identification of these sets of difficult numbers, as well as reminding me of the letters which I also confuse between each other, and even the word, “SUDOKU,” causes me to interchange certain phonetic sounds, as I used to rigidly mid-pronounce, “Sudoku as SODUKO,” so my problems continue and I know that my writing skills are generally unaffected except by the problems I am having from plagiarizers who are stealing-&-hacking-my-original-completely-solo-intellectually-protected-materials which I am seeking the FBI and NSA to assist me to ascertain who all these culprits are, as I already know of several different people who are involved with RELIGIOUS-Cults who are hacking-&-key-logging-my-writings to steal them and THRY have bragged to me they won awards and money for my writings which they hacked-stole-deleted-from-my-accounts-&-published-as-they-counterfeit-&-stolen-property, and so I am continuing to seek federal interventions to stop these predators-&-this-system-of-intellectual-slavery from continuing, as I am a lawful U.S. Citizen protected by our Bill-of-Rights as well as the other Amendments, and the only thing protecting me from being kidnapped-&-trafficked-into-Mexico-by-these-plagiarizing-thieves is my dependence upon my Social Security status as 100%-Physically-Disabled requiring extensive-medication for my Pulmonary-dysfunctions-&-permanent-decreased-ability-to-breath-normally!!! Thank you!!!.Version: 1.9.9
Fun, Enjoyable, too many adsOverall, this is a five star app. I have been playing for about a year. I like the notes option to place numbers in boxes, and that they remove as that number is used, that was thought out nicely. Suggestion I have for the developers, add an ‘X’ to the notes section; sometimes I just want to ‘x’ out all the boxes for a specific number or pattern. My issue with the ads, I watch them for the most part but some of these ads have four or six pages for the same ad that you have to click out of each time. Many times I will just close the app and reopen to get out of those multi page ads. Thank you for an enjoyable app..Version: 2.3.9
Wonderful Sudoku game!I have been playing Sudoku for many years and I currently have 6 other Sudoku games on phone. This one is quickly becoming my favorite. It has all the possible options. Different difficulty levels. Mistake limits. Auto complete. Time limits. Everything! To all the others. Please only review the game itself. Don’t simply complain about ads. Ads are advertisements. Advertisements are commercials. Commercials are commerce and commerce is money. They need money to make the game so complaining about ads is just a waste of everyone’s time..Version: 1.6.9
Sudoku MasterIt’s enjoyable without being stressful. One wish less ads but I didn’t use that against the five star system. Fairs fair there are costs involved…. I really like the experience spread. At 72 I’m a little slower than I used to be. I like the size of the blocks and how easy it is to read. I’m an old sudoku fan from way back this flies as high as any others I’ve played. Keeps my mind pretty alert and helps jiggle those little grey cells. Wishing you joy in puzzling, God Bless, always.Version: 2.1.1
Teaches how to solveI like how this app shows you the rules on Sudoku so that you know what to look for when you get stuck. I don’t like the ads. The game is on a timer, so I will be thinking about my next move when it breaks into an ad. Then when it returns I have to refocus, and remember what I was doing, which takes more time. So it’s not really a reflection of how long it actually would have taken you if you were allowed to follow through without distraction. In other words, the timer is kind of a moot point. There are lots of settings though, so I’m not sure yet if it’s an option to just turn it off. It’s a good app..Version: 1.6.9
Just like the restThe game is fine. The commercials they show takes a year to play, so you can skip. The ad for this app is, “a puzzle a day keeps the stress away”. Your ad was so long that I cussed my phone out and am close to deleting this game. Royal Kingdom has the longest and most annoying ads on the planet. Your game brought me a great deal of stress actually! I understand that ads pay for the game. Have shorter ads. We didn’t want to play it the first 60 seconds of the ad, what makes you think we’ll decide to play it for the remainder of the 5 minute ad? This is why I don’t play any games anymore! Your ads are too long!!!.Version: 2.2.0
Great game but some issuesI love this game! But I’m having issues when I close the app and then open it again and try to play my last game I was playing, it just completely starts me over 😔 doesn’t save any of my progress! Even the notes on it are gone. It’s got to the point to where I don’t even want to play anymore. Anyway to fix this issue? would love some feedback! Has anyone else faced this problem? How did you solve it?.Version: 1.8.3
Fun, could be even more so without so many adsI have become obsessed with playing. It’s fun and I enjoy the different levels. The only thing that would make it better and is preventing it from being a 5 star for me is a paid ad free version or at least minimize the ads! Giving me 4 “chances” to download other games is not going to entice me to download them after I’ve already ignored them the first time. I end up tiring of the ads long before the game and remove the game just so I don’t have to deal with ads. Edit after a few more days of playing and I removed yet another start as the ads are now coming more frequently, including right in the middle of a game! I get that this is how they get revenue but it’s a major turnoff. Constant ads, ads that are too long and extremely repetitive. At this point I might as well just buy a bunch of sudoku books and not bother with playing on my phone at all.Version: 2.0.8
Fun and challengingI really like this game. Most of the ads are short enough to bear, but for some reason, when you win, they make you sit through a ridiculously long ad. I wish they gave more chances if you make a mistake. If you accidentally hit the wrong button and you run out of chances, you have to sit through a painfully long ad to get another chance. Ads are really killing the game industry and taking the joy out of it..Version: 1.9.2
Never played beforeIt always seem too difficult and strange to play. But this version has taught me how to play and I have enjoyed it very much. Before this, I didn’t understand the rules on how to follow the numbers. I was just doing it kind of like in a random order. But sodoku master has taught me how to. Board from all different directions and I may not be a master yet, but I’m not a novice anymore either..Version: 1.7.3
Love itI love sudoku where I can hold a number and do them all at one time instead of having to click the cell and then click the number every time. I like to be able to have a lock on it and not very many have that feature. In general, this is probably my favorite sudoku. I just wish you could get rid of the ads. I would pay a couple of dollars to get rid of the ads because they’re annoying every single time you play One game..Version: 2.0.6
It’s a good gameI recently got sudoku books and I hade no idea how to play downloading this game actually helped me how to play and now I know how to play. It is really fun and it helps keep your mind going so instead of taking a break you could take a break while doing this it does make you think a little bit, but it is very fun. I would highly recommend you to download it..Version: 2.0.7
A rare feat about this oneA sudoku game that doesn’t interrupt it’s users mid-game with an unskippable 60 second ad?? What is this sorcery?! I never EVER make reviews on the app store, but this game has been my favorite app to play as of late and it’s all for one simple reason… ADS! As someone who absolutely DESPISES the overwhelming approach Apple has towards ads in their games, I love the restraint with the programming of ad popups. I rarely get ads before I can load up a puzzle which is amazing compared to most mobile games which will slam constant ads in your face before you can catch your breathe! Talk about desperate… Not this app tho! So if you’re looking for a peaceful game of sudoku (one that’s very well-designed), THIS is where it’s at!!!.Version: 1.9.5
I can play this game!!For years, I could not place this game of numbers. People would try to teach me, and yet, I didn’t get it! So while playing some games on my phone, I decided to give it a try. The instructions which are not a lot but the lightbulb turned on in my head finally! This is a great game to learn..Version: 1.8.0
Too may interruptionsI have played this game for months. I do not mind the ads between puzzles. I expect that even though it is kind of irritating that you get an ad after a game and then another when you hit the button to play the next level. Lately it has been throwing in ads right in the middle of a game. Some instances more than one time during a board. This is about to be a big deal breaker for me. It has ruined the whole flow and enjoyment of the game!.Version: 2.3.7
Great Game, Lose the AdsI love Sudoku, and playing this fame has greatly improved ny skills, BUT, right when you are about to solve a difficult riw ir column, an ad pops up. These are not short ads, they are long ads, and it is constant! You lose your place, and your train of thought. Sure, you can pay to remove ads, but when I can’t afford to buy groceries, I’m not going to pay you to remove ads. You could cut the amount of ads in half, and still have FAR too nany!.Version: 2.4.7
Ads & playing musicThe game itself is fine, my two main gripes are the constant ads and how difficult it is to play music while playing. I understand the game needs to make money so they run ads but there is no reason for me to be getting an ad before a puzzle, two ad breaks during the puzzle, and one more after i complete it. And when you're listening to music it constantly pauses during the puzzles. I don't know what that's about.Version: 2.1.6
DawggtiredI chose your Sudoku game because there were to be no ads. You failed to mention that you would be pushing your games at me at every opportunity. Also that smiley face with the thumbs up is pretty annoying. On the plus side I do like your version of the game. I'm now a paying customer, but the game doesn't recognize me on my iPad. Subscriptions don't transfer from phone to I pad?.Version: 2.4.0
Keep followersThis is the first game that helped me understand Sudoku. Yes, plenty of ads, but that’s part of it. Between rounds and after a wrong moves, I get it, which plays incentive to concentrating and making logical moves. Today a new “feature” of yet more ads in the middle of game play, even when no wrong move has been made. Give me a break. Not cool. Especially since the thumbs up “genius” comes across as sarcastic, rolling into yet another ad..Version: 2.3.8
Clue is cluelessSo I watched a few clue videos, so I can get an idea of one square that I was curious of what it might be, but for some reason after watching a video, the clue automatically shows me an answer for something I didn’t ask for. I thought it was a mistake so I tried it a couple more times and it kept giving me clues for something I didn’t ask for. Which I just dismissed because I didn’t want those clues. Very frustrating..Version: 1.7.8
5✨I just learned sudoku with this and I’m so happy! My grandpa used to play it so I wanted to learn it to honor him in a way and it’s just amazing I really didn’t imagine myself playing sudoku this much plus I like the way it makes me think logically especially during school breaks when there’s nothing to keep my brain active.Version: 1.7.2
Good game but Ads ruin it.The Sudoku app works great. The puzzles are easier than their ratings. The ads are crazy. They make you tap 3,5 or even 5 times in order to get the ad to stop. Plus the ads are mostly deceptive, putting the infinitesimally small exit icons in hard to touch areas, or dropping you into the purchase screen after trying to exit the ad. It got so intrusive that I had to unload the game..Version: 1.9.9
Highly Recommend!I have used a bunch of sudoku apps and this is by far my favorite! There is minimal ads and it catches when you put notes that don't go in the box. It has many different level types, you can challenge other people, and do a daily challenge. Love it!.Version: 2.0.8
Great for beginnersI am not a complete beginner, but I have not played Sodoku for several years. I like this version because it gives me beginner pages, and it will even help find a missing number if I can’t find it I’m looking forward to getting more experience and moving up..Version: 2.3.8
AmazingI absolutely love this app. There isn't many adds and it's very entertaining to just play sudokus in South an easy way. I play these all the time. I also love how it doesn't take Wi-Fi so I can play it werever I want. I 100% recommend downloading this app if you want a nice and easy and fun experience playing sudokus..Version: 1.7.8
ExcellentI have used a lot of different sudoku apps over the years and this one wins out for sure. It has a notes option, hold function to long-select a number, nice aesthetic and animations. Just all around great sudoku app. I hope they don’t change a thing..Version: 2.1.7
Good for your brain (:I feel like i’m training my brain to stay more focused on numbers & problem solving! also superrrr helpful and satisfying when trying to pass time… plus, they have a bunch of other games you can try out, those are also pretty cool.Version: 2.4.2
Ads is the ConLove playing it after work, put on some music and play, but lately I’ve been getting flooded with ads. I literally got 3 ads within the span of a minute. I got one while playing a puzzle, then finished the puzzle and I got another one, then another one for starting another puzzle. Such a turn off..Version: 2.1.0
AD HeavenIf watching ads every single minute while you are trying to solve a puzzle is relaxing to you, then this is the perfect sudoku app for you! The best part is there’s no way to get rid of them and they last about a minute each..Version: 2.1.7
Great game, fake tourneyThe gameplay and design are both really good and the hints are setup where they will explain the move. However, the weekly tournament is 100% fake. You aren’t actually playing against others. It’s fake people the game creates and they increase their scoring as you play more. It’s very misleading. Why can’t they do actual tourneys?.Version: 2.0.8
Great App But the Number of Ads is RidiculousI love this app, I really do. But they have recently upped the number of ads during gameplay. It is frustrating to be on a roll only to have your thought process interrupted by a lengthy ad. I can’t make it through a puzzle without at least 5-7 ads interfering. Sadly, it’s time for me to look for a new sudoku app with fewer ads..Version: 2.4.4
My favorite right now!!I’ve struggled with my mental health for a while now and I’m often feeling very overwhelmed with everything going on with my life. Sudoku helps me cam down on those days that calm seems like a million miles away. I definitely recommend this app!.Version: 2.1.0
Tougher than it looks!Finally a game that is tougher than it looks, but not so impossible to be infuriating. You lose lives for mistakes, but at least the ads are short, and you get another chance. I may have found my new favorite game..Version: 1.9.2
Great versionGreat game. I like the challenges, deactivating of the motivational elements and additional games are fun. My only critique would be to add a Google or email linked to the game to save progress as an option. Otherwise, well done! This app is the best app of Sudoku that I have found so far..Version: 2.4.4
Nice SudokuEasy to use and understand. No high pressure timer where you feel anxious about not getting the puzzle finished before a countdown ends. It’s fairly add free. Basically after you solve a puzzle there’s an ad. But it gives you time to chill for a minute..Version: 1.8.3
Fun Fun FunI absolutely love this app. I like doing so, Dooku and I find it very easy to work with. I bought the app with no ads. Great for the brain to keep it working. Makes even the hard ones easier. and it doesn’t let you fill in numbers that don’t belong there..Version: 1.8.3
Sudoku master?!The ads between levels are tolerable but after a couple of weeks of playing it has started playing ads during the gameplay. Completely gamebreaking experience, until that started I would have gave this game a strong 5, I like the puzzle designs but the in-game ads have ruined it for me. Deleting...Version: 2.3.7
Okay Game, but…This is a typical Sudoku Game that I’ve enjoyed quite a bit. But… the game has too many ads. They are brief ads, but they appear before, after, and often in the middle of games. Ads have increased since I began using it. Moreover, the fee for removing ads is monthly and not insignificant. You can find sudoku games of good or better quality that are less greedy..Version: 1.9.2
IntriguingSudoku Master is a fun, exciting game. It helps my concentration. Thank you. I love games that make you think/make your mind focus on what you’re doing..Version: 1.8.2
Awesome!I’ve tried Sudoku a couple of times before, on paper, and couldn’t solve any puzzle, not even at beginners’ level. That was why I have been ignore this ad for this app. But I finally installed it just now, and I just realized that the app actually explain to you the strategies! I just finished my first puzzle! It was fun! I think I’m already hooked! 😄 So glad I downloaded this app!.Version: 2.4.4
SudokuFinally able to master this puzzle game. Computer is easier..Version: 2.4.7
Sudoku MasterGreat game. Not sure an IQ can be measured by the level of game or the time it takes. A great game to challenge oneself with numbers..Version: 2.3.9
Add on suggestionPlease add the option to send invite links to people to battle, the battle option is very fun but I'd love to be able to do it with friends too instead of just random people 🙏 It would make the app so much more fun.Version: 2.4.3
Note numbersPlease have the note numbers on a separate line, instead of an on off switch. The number of times I fill a note number in and the note is switched off and I get an error is crazy..Version: 2.4.3
