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 love the game but am annoyed by the ads that interrupt the actual games as these make you lose your train of thought. I can accept ads before and after the game. I see there is a possibility to remove ads in the settings but am guessing this is not for free. Other games apps do not interrupt the actual game with ads. The number of interruptions to each game is now at least three. I am really thinking to uninstall this now as it takes away from the enjoyment of playing.

I like the game. BUT, few things to comment: - I wish there was a way to restart a game. You got almost the end. You figured you did a mistake. It's probably better to restart than do 'undo' to the beginning. - could be great if the "hint" could be disabled or at least located in a place where I will not press it by mistake. So annoying. I never use it and don't want it. - could be great to have the option to choose & have only specific level (e.g. expert) on the daily puzzles and events.

Soo i like the game itself, i've done a lot of sudoku's so this is a fun new challenge... BUT they started putting a lot of ads in the app... first it was just one after every single game, that was okay to me... but NOW it's like 5 ads during the game! How am i supposed to beat my record when i keep getting pulled out of my focus while in the game?? VERY annoying!
