Great game puzzle, and I enjoy playing it. However, there are too many ads interrupting at the most inopportune times. While we can escape most ads after a few seconds, there are a few that continue on in circles that don't allow one back into the puzzle. The only way back to the game is to close the app and restart. This annoyance drops the rating by one star.

Actually a good killer Sudoku app - but the advertising is just annoying. The game is interrupted several times for minutes. Sometimes I have to close the app and restart it. I would pay, but if I go to the corresponding button, I should immediately enter into a contract without knowing the price. I read similar things in other comments. Why is the price so top secret??? This makes it look very dubious. If there is no transparency, I will delete the app again

An incredibly addictive game - I often play at night and turn my WiFi and data off so that I don't get any adds or distractions before bed. However, the expert sudokus could be harder... Unfortunately they're not very challenging anymore but this is not really a problem. This was going to be a 5 star review, but I had to update the app to review and the layout changed from the original simple design and wiped my statistics - I lost my streak and my best times and scores. Very disappointed.

It is impossible to play after the ads appear in the middle of the puzzle. Constantly interrupts and distracts, which is why you have to spend extra time to return to the solution

Idiotic ads. I understand you have to push these but running these for 2 minutes in the middle of the game is too much. Deleting the app.

The game is so overloaded with advertising that you can't get to know it. Immediately deleted again

The game is good, but the ads are just terrible. There is a lot of it, but this is not the worst thing. Often there is such a crisis that it is impossible to close. Not in a minute, not in two...

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.
