What is Killer Sudoku

Killer Sudoku is a true legend among number games and puzzles. In a nutshell, it’s a perfect blend of those fave brain-twisters Sudoku and Kakuro. Absolutely free!

This number puzzle goes by many names: Sumdoku, Addoku, Cross Sum, etc., but the rules are equally simple across the board. Your goal is to fill the grid with numbers like in classic Sudoku while making sure the sum of numbers in the cages (areas separated by dotted lines) is equal to the number in the upper left corner of that cage. Still sounds complicated? Let’s review the Killer Sudoku rules in detail.

How to play Killer Sudoku

✓ Fill all rows, columns, and 3x3 blocks with numbers 1-9 exactly like in classic Sudoku
✓ Pay attention to the cages – groups of cells indicated by dotted lines.
✓ Make sure the sum of numbers in each cage is equal to the number in the upper left corner of the cage.
✓ The basic rule of Killer Sudoku is that the sum of all numbers in each 3x3 block, row, or column always equals 45.
✓ Numbers cannot repeat within cages, a single row, column, or 3x3 region.

★☆☆☆☆

I was able to put up with the intrusive mid game ads most would be put off by. But now you NEED to click on them and go to the play store just to go back to the game? No exit button on the ad? is that even legal??? Absolutely not putting up with it. If you're interested in the type of game, there are better, less intrusive/harassing apps to play it on. Absolutely ridiculous.

★★★★☆

I really enjoy Killer Sudoku, but I wish I could see the score of the game as I finish. The screen with my score disappears in the blink of an eye and the current score does not show anywhere in the summaries. ☹️☹️. difficult to keep track of how my games are going when I can only see the very best score of the day, week, month and not the rest of my play

★★★★☆

I think that the difference between levels "hard" and "expert" is too drastic. the Hard level is too simple. There are too many single digit cells that take no effort to solve. And while I enjoy the Expert difficulty, there are inconsistencies in its difficulty. Sometimes it is almost impossible to solve without a hint because there is no way to narrow down the cells. Knowing the right tricks for solving helps, but I feel like there could be a level between to keep the levels consistent.

★★★☆☆

There are way too many ads. within one game, you can see anywhere from 7 -15 ads. It's not predictable. But for 1 game, it's extremely excessive. I also don't like how this doesn't have auto fill at the end if your notes are all right. I love that feature on other puzzles.
