  • A fascinating game, expertly implemented Aug 31, 2018

    By NSException
    I’ve been a fan of logic puzzles for most of my life, but I’d never heard of kakuro until recently. After trying it once I was an instant fan. Don’t let the math intimidate you: this is a direct relative of sudoku. Apart from the fairly simple sums, kakuro follows the same basic sudoku-style formula. You establish possibilities and then eliminate the impossibilities. This isn’t the only implementation of Kakuro out there, but it may be the best. Real Kakuro provides a beautiful, functional interface that doesn’t get in the way of the game itself. It offers optional guidance to completely eliminate the need to solve the addition problems, but this is easily disabled. In short, it’s simple, it’s fun, it’s great.

    Good but can't change settings. You get annoying 'clapping' bar that covers most of the screen whilst trying to play, which happens every time you put a number in, which is v annoying having to wait for this to clear. I'd rather the option to remove this.

    I am having a great deal of problems with the app since the last Apple IOS update. I have had a few issues with the two updates prior to this, but it is horrible this time. A majority of the time when I complete a puzzle it kicks me out of the app. When it doesn’t, it shows me the ad, then allows me to open a new puzzle, but will not let me play until it kicks me back out or I close it and open it back up. Finally, two times now, I have had it go to the ad then instead of closing it, get a black screen with the Google ad in the top inch and black screen for the rest and it does not do anything. I cannot play at all right now, even closing it down and going back in is not resetting it!!

    Very challenging, mentally. While a few squares can be filled easily, as their solution is obvious, there are many others which force us to rack our brain cells to work out various permutations, to get to the final solution.
  • Starting on my 2nd time through! Jan 22, 2020

    Love Kakuro! Used to play this years ago in Games magazine before it went overseas and got renamed. Finished all the levels and have started my 2nd time through the game. This is a well done app and the games are appropriate for each level. The only issue I’ve run into, is that if I play too long without restarting the app, it will suddenly go back to the main screen and appear to have lost all progress on all levels. If I close and restart, everything is fine, but it was heart stopping the first few times it happened. Anyway, I highly recommend this game (and any others from “Real”.) Thanks for the awesome game, guys!!

    One of the few games I really enjoy because there aren't any flaws. Or at least I haven't found any yet. The different levels would challenge almost everyone. I would REALLY like to find more card or sudoku games by Deucher. Would give it a SIX star if i could.

    I gave this five stars because it deserves it for what you get. There are so many puzzles, you will never run out. It doesn’t ask you for money. I guess there are ads, but they never bother me. I was doubtful they could be challenging enough while still being small enough to fit on the phone, but definitely some of them are. My one big wish: please please please give us an undo button! Sometimes I will discover a flaw in logic after I’ve already made a number of entries based on it. I need the ability to back up several moves because there’s no way to remember everything I need to correct.

    I absolutely adore this game. I have played a lot of different Japanese number puzzle games on my android phone and this is easily the best one. I would like to be able to reset all the puzzles without needing to delete the game. It is well worth the small cost for the ad free version. Thank you!

    the best time passer I've had last year. i have unfortunately completed the entire game. but i loved it and it was wonderful for me to just play this while listening to music in the background.

    If you like Kakuro, this is a great app to pick up. Each level has enough games in it to keep you busy for a long time. And if you do play a lot, you'll probably find the next level beckoning to you. And there's also the challenge of re-visiting problems you solved early on, to see if you can beat your old score. (Trust me, it will seem like you're playing it for the first time, again.) This is my first review, and I'm not getting anything for it. I just felt had to write it, and alert you Kakuro players about a great deal!

    Fun, lots of levels. I did all the Hard puzzles, and have started on the Challenging level. I can tell the difference, so I think anything beyond that will be beyond me! :-b
  • Love this game! Math/logic game Dec 13, 2020

    By imlemonyfresh
    If you like sudoku, picross, 2048, blendoku, hashi,slitherlink, link-a-pix, nurakabi (sp?), or any kind of logic picture/number game you’ll love this, especially if you’re into numbers. This one is mathy and if you’re especially good at math or fast with basic math, you’ll want to stick to the expert ones. Maybe the hard ones when you’re bored. If you know about this kind of game, here they put the possible numbers so it’s even easier and almost makes you feel a little guilty.

  • Fun game, buggy May 24, 2016

    By JohnJohnGoose
    Kakuro is fun and this is a pretty good app for it, but whenever you click a banner notification, receive a phone call, or get a pop-up notification (low battery, calendar, etc), the app's display becomes unresponsive and you have to hit the home button to goto your home screen and then double-click the home button to select Real Kakuro again to make it un-freeze. Annoying if you frequently get phone calls or calendar notifications or if you want to see what the banner notification is trying to tell you (new email, etc).
  • Formatting Please Dec 17, 2018

    By Herc the Dog
    What a great game and a great app! There are many, many hours worth of fun here. My only complaint is that the board and number grid are so small on the iPhone X. It’s unnecessarily difficult to make selections. With some simple formatting changes, or better yet formatting options, it could be much easier to read and make selections. I’ve also run across numerous puzzles that seem to have multiple solutions or where logic can get you only so far, after which guessing is required. These kinds of puzzle are no longer logic puzzles.
  • LOUD advertisements May 30, 2020

    By SmartiePantsTwo
    I would have given this a five-star rating except it has begun playing the advertisements between games at full volume, every single time. This is extremely annoying since I commonly use this app for filling in time while I’m waiting, usually in public locations. Having a very loud advertisement begin blaring in an otherwise quiet environment is really bad. This has made it so I can no longer recommend this app, nor use it in public. Other than that, it is a very well written program and works very nicely.
  • Black Screen Bug Mar 6, 2020

    By CykoCy
    First, for those complaining about too many adds; the developers need to make money. If you don’t buy the no-ad version, then tough it out. Next is my big issue. After completing a puzzle, the screen goes black and there’s no recovery unless the phone is powered off. This makes the app almost unplayable. This needs immediate attention. I love Kakuro. This app, when working, is well constructed. The last update was a year ago, so I foresee more issues down the road. Too bad. It’s fun. But I’m deleting until they fix the bugs.

    Enjoyable & relaxing. I very much enjoy number games. However, I play this game on my phone and the number pad is very small and sometimes hard to work. There is plenty of empty space for them to enlarge it.... (hint hint)
  • Jan 7, 2021

    By Phil Evans
    So far I've really enjoyed this. Lots of puzzles, be organised by difficulty. Interface is nice, especially the ability to use a pencil to draw in possible values. Only two minor criticisms. First, I find the difficulty levels a bit inconsistent: some "hard" ones I find easier than some"medium" ones. Second: I sometimes find the number pad less than responsive, but that may be my phone. Oh and I wish I'd realised earlier you can turn the cheat sheet off!
  • Great, but.. Dec 20, 2018

    By I.Play.Mayonnaise12345
    The app is great with literally hundreds of puzzles per difficulty level (over 500 extreme puzzles). Good interface and controls, but occasionally the puzzles will have a block with more than one solution (an enclosed area that does not affect any other area of the puzzle may have two different digit combinations possible). While this is annoying, it does not affect gameplay much in a pretty much otherwise flawless app.
  • Hard with large fingers Nov 3, 2019

    By Engstewart
    I enjoy this game and it is well implemented. My only complaint is that the number pad is very small and my large fingers are constantly accidentally pushing the wrong button. I recommend playing the pencil/pen and other icons vertically in order to make the number pad larger to improve the user experience. I love the love of the game board with the tattered pages, but not at the expense of usability. Thanks for your consideration.

    Fun game. Would be nice if the cursor guessed which square to move to next, especially when I'm working on a number with only two spaces.

    The puzzles are nice, but the app crashes after every level is completed. Please fix this bug. I have to restart the game everytime I complete a level which is annoying.
  • Nice, but the ads and glitches May 24, 2016

    By BernalTemple
    This is a good kakuro game. Beautiful graphics, solid game mechanics, a large variety of challenging puzzles...but. The ads are rampant. The show any time you open the app (standard), but also any time you bring the app from background, even if it was only for a moment to check the time or another app. And those ads case the app to break down. Freezes, graphic glitches and so on. If they want me to pay to get rid of the ads, this is the way to NOT get me to do so.
  • Great game but... Sep 7, 2018

    By Sunrize222
    This is a great game, no doubt about it. It makes you think and use different parts of your brain than you normally use. It’s well laid out and has an attractive face. The reason I gave it 3 stars is the ads. I get that you want to make money but please tone down the ads and have a way to mute them. I have to turn the sound off on my iPad or the ads blare everyone around me. Most games allow you to mute the sound. A few less video ads would be really appreciated.
