## What is Real Kakuro 20x20 Free?

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.

### 5/5 — Help please

*2026-03-21, version 2.3.3*

I enjoy this game but🙁, when you play the same game over and over, but can’t figure it out, isn’t there a way to solve it? I like to do the same number on each level before I go on. But when I get stuck, I don’t move on till I’ve solved the puzzle. Last time I made it to #33 on each level, then got stuck. Got so aggravated I quit. This game is very good for your brain, I don’t want to quit, but I feel bullied when there’s no help and I’m 72 years old. So, is there any help to solve the puzzle that I’ve not seem? Thank you for your help.

### 3/5 — Great app when it works.

*2025-08-06, version 2.3.3*

It won’t let me restart a puzzle if I realize I am stuck and can’t figure out where I went wrong, and sometimes the app won’t even open. I have had to delete and re-install several times. It’s great fun when not glitching though.

### 5/5 — Awesome math puzzle

*2024-09-04, version 2.3.3*

I’ve been doing these math puzzles in books for decades. This app is a perfect version of this game for my tablet. No complaints, no changes to recommend. Just love it!

### 5/5 — More level please!

*2024-08-11, version 2.3.3*

Such a great games, I enjoy it very much.
Please add more level: I’ve done them all and craving for more!
Thank you!

### 4/5 — Wonderful brain exercise

*2024-04-10, version 2.3.3*

I love this app! But I have one complaint…it doesn’t have more than 80 puzzles for each level.  I have to delete the app and re-download to start over again.  I need MORE! 🤣

### 5/5 — Great Logic game

*2024-03-09*

This is a great game to help keep focus while paying attention to detail. I love it!  Play on!

I do not like it when something breaks my concentration, and I loose my train of thought. So I would like to be able to reset an individual game. 

I’ve finished all 80 Extreme games several times, deleted the app, and reinstalled again.  So I would like it you could reset all without deleting app.

### 5/5 — Excellent

*2023-11-16, version 2.3.3*

I just finished all of the puzzles in this app. I have the standard sized one on my phone, but this 20x20 version is nice for the iPad. I was 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 that’s more of a pet peeve, so I’m still in 5 star territory!

### 5/5 — Great game even the second time around

*2023-09-12, version 2.3.3*

Love the real Kakuro. Have done all extreme puzzles so I erased them and did them again. Great game.

### 5/5 — Great

*2023-05-03, version 2.3.3*

Going round again

### 5/5 — addicting

*2023-01-01*

i enjoy kakuro, i have trouble putting it down. i do wish there was a 
way to check your answers if you can’t solve the board. i have one in the extreme i can’t solve and i hate to give up on it!
