Real Kakuro 20×20 Free – Entertainment Game Review
Real Kakuro 20×20 Free is a Entertainment/Puzzle/Board game from Luiz Deucher, first launched in 9th November 2011.
It’s rated 4+ and currently has 131+ ratings on the App Store.
What Makes Real Kakuro 20×20 Free Stand Out
Now with 400 puzzles! The biggest kakuro board available in the App store gets really better!
Kakuro is a world phenomenon like Sudoku. It is like a crossword puzzle with numbers. Each "word" must add up to the number provided in the clue above it or to the left. Words can only use the numbers 1 through 9, and a given number can only be used once in a word. Every kakuro has one and only solution, and can be solved through logic alone.
Real Kakuro 20×20 for iPad is a very elegant game, providing fabulous gameplay experience.
- Clean board, providing hours of pleasure gameplay;
- Handmade unique challenging games. All games and categories were designed to fit a 20×20 board without compromising quality and the need of zooming;
- Autosave game. You don't need to worry if you don't have much time to play. It will automatically save all unfinished games;
- Simple menu context. Your game is just a few clicks away;
- No in app music. You can play while listening your own iPod library;
- High definition graphics for iPad;
- Game Center statistics. Compare your results worldwide.
- Simply the largest kakuro board available in App Store.
- Requires iOS 4.3. Update your iPad on iTunes.
Please note: We had a hard work building those 400 puzzles and are offering them all for free without locks or having to ask user to pay for additional puzzles. And we know how annoying ADs are. But we need them to keep this game live and updated frequently. We give the option to remove all ADs (including the popups) via in app purchase.
Thanks for your understanding and support.
This Entertainment game offers engaging gameplay and regular updates for mobile players.

Community Insight:
Ive been doing these math puzzles in books for decades. This app is a perfect version of this game for our tablet. No complaints, no changes to recommend. Just love it.
We just finished all of the puzzles in this app. We have the standard sized one on our phone, but this 20×20 version is nice for the iPad. We were disappointed that there were only 80 puzzles per level. Would like to see them add more. Also, the other version of the game lets you erase pen marks and leaves the pencil marks underneath, but this version erases everything. Or it might be more accurate to say that the pen marks overwrite the pencil marks instead of just covering them up. That can be annoying when you have a particularly hard puzzle and you need to resort to trying out combinations to find where the solution breaks, then go back and try another one. But thats more of a pet peeve, so Im still in 5 star territory.
Love the real Kakuro. Have done all extreme puzzles so we erased them and did them again. Great game.
We enjoy kakuro, we have trouble putting it down. We do wish there was a way to check your answers if you cant solve the board. We have one in the extreme we cant solve and we hate to give up on it.
We enjoyed working the puzzles provided. Wish there were more.
We were so excited to see this in the app store. We love the larger grids; they are a challenge.
This is a great app to play on our iPad. However, each puzzle is static – that is to say, you cant zoom in and must play with the entire puzzle in view. Because of that, playing on our iPod touch was nearly impossible, as our big fingers would tap on the wrong squares two or three times before getting the one that we wanted. If you have a larger device and like Kakuro, then this is by far the best app. It also provides another useful puzzle source for old-school pencil-and-paper puzzlers like us. We take screenshots of the blank puzzles and print them out to do them by hand. With the high resolution quality of iPad screenshots, they come out fantastic, even when we print them on a full page at about 8×10 (on a standard 8-1/2×11 sheet). So if we dont want to lug around our iPad (like when Im waiting in the car to pick up the kids from school), we have a few of the printed out puzzles on our dollar store clipboard and we dont have to worry about screen glare or battery charge. Also, the quality of puzzles here are MUCH better than others you can find online – we have tried dozens of websites and it isnt even close.
We love this app! But we have one complaintit doesnt have more than 80 puzzles for each level. We have to delete the app and re-download to start over again. We need MORE.
We love the game and ease of gameplay. Our only complaint is that we wish additional puzzles would be added.either free or packs for purchase. If add more puzzle options, would rate 5 stars.
We prefer real Kakuro more challenging, quicker, more puzzles. Love Real Kakuro.
Love real kakuro, and the 20×20 looks like fun…but our eyes need the zoom feature. We'll wait for an update that includes that…then make it 5 stars.
We haven't looked for a kakuro app in a while because they used to all be crap. Excellent gameplay and beautiful stylistically, but the interface suffers from style over substance. The poor contrast and lack of zoom makes the game very difficult to play to relax before bed.
These puzzles are so fun! Please make more.
We like the Conceptis brand Kakuro books and this app reminds us of those books. We really enjoy it. It does crash upon starting some puzzles, but we can't complain since it's free.
Love the extra challenge of this larger version of Kakuro. However, lately it has crashed when opening some (random) unfinished puzzles. And we too would like to see our pencil marks when we erase a "penned in" number.
We love Kakuro!! In the Real Kakuro app, when you use both pencil marks and then a pen mark, hitting the eraser will return you to the pencil marks. Any way to get the same feature in Real Kakuro 20×20? It will get you 5-stars if you can do it.
We love this app, with the same gripe about too many pop up ads that others have mentioned. We can solve the Extreme puzzles within 15 minutes (personal best) to an hour, averaging 45 minutes. Extreme 16 is unsolvable. We've been analyzing it for hours. The problem is in the lower right hand quadrant. It would be great to have an in-app purchase for solutions. We are convinced this one has an error.
We've been playing this game for over a year. We're on our 2nd time through. But the game crashes at least once on every board. Add that to the ads we MUST watch, we're about ready to find a different version. Stop the madness.
Love the game, but it keeps crashing. We open a puzzle and before we can enter a single number, it closes. Will re-rate as 5 stars after you fix this.
We haven't had problems with it crashing. We really like the different play levels. No complaints from us. We would give it five stars.
Allow rotation to landscape. The game is great. We don't even mind the ads. Playing on an iPad is less than fun because you have to hold the pad in portrait mode with the power plug at the bottom.
Love Kakuro in general, but this app crashes a LOT. It's always reopened with little or no lost data SO FAR. Still annoying.
We like the game but it tends to be finicky and crash. There is on puzzle we can't play because it crash every time we open it. Others seem to work fine. Another was fine and then we left it. Now we come back and it crashes every time we open it. If they would fix it we'd give 5 stars.
This app would be fantastic if they would update to fix the crashes. There are some puzzles that we cannot complete because as soon as we open them the app crashes. Doesn't happen on all, just some. Very puzzling. We really like the various difficulty levels and board sizes.
This latest update completely ruins the experience with full-page ads that randomly pop up during gameplay (sometimes causing you to accidentally click on them if you're in the process of making a move). In addition, there are now animated ad banners at the top of the board, covering part of the game, specifically the game number and difficulty. Would prefer the previous version, or at least a working "remove ads". Uninstalling.
Now that the update is complete, game works fine.
After update, we're now getting popups during the game. What gives? Stupid.
Easy to play, and no annoying "gotcha" tactics if your finger wobbles onto the wrong square when the car jolts.
Medium 20 IS solvable! Great games. So much more challenging than soduku! Wish there was a little bit easier way to navigate around the board.
This is the best Kakuro version we have found. It is easy to use and requires fewer button pushes than most.
We were so happy when we discovered the 20×20 version! We had already finished all 1000 puzzles in the regular game and now we have more! Great app; no problems with it at all. Fun game.
We enjoyed the puzzle books, but we LOVE the app! The puzzles are challenging, but with perseverance–solve-able. Easy to play, and never a glitch. We highly recommend this app for anyone who loves number puzzles.
This is the same as Cross Sums, which we have enjoyed solving for many years in Dell puzzle magazines. We like the various levels of difficulty. We also like the fact that there is a timer, so we can try to beat our previous times.
Perfect mind puzzle. Can go on for hours.
Fun so far and fairly challenging. We have only found one puzzle so far that is unsolvable. We love kakuro and love this app.
We love this game, we play it for hours if we can.
If your a numbers junky and like a good challenge this is the game. We don't even bother with soduko anymore.
Ever since the last update, it has crashed. The challenging and extreme levels are really challenging and fun. But we are running nearing running out of games.
This is a great app for kakuro fans. We'd like an option to turn off the auto calculations down the bottom for an added challenge because now we feel like we're dependent on it. Great app otherwise.
Really good app. It's our go to stress reliever.
Excellent Kakuro app. 500 large puzzles for free. Very good UI. We recommend it for fans of Kakuro.
Love that this game is available. Definitely an addiction, but a good one… :).
Time flies when we play this game. Love math and love logic and this combines it all.
Love this. We played the other one also (smaller boards). Once you start you can not stop. We play on our iPad and have no problem as it does not crash. Though we do wish that we could turn the board..just our preference.
Great app, we play all day long.
We're a huge fan of cross sums puzzles and this is a nice implementation.
We play everyday and never get bored! We love it.
We look forward to the challenge…..every evening! Great game.
Love the graphics and the game play.
Absolutely love this game! No complaints. Would recommend to any puzzle lover.
