Killer Sudoku by Sudoku.com

Killer Sudoku – the development of logical and spatial thinking through the solution of numerical puzzles. Choose from an easy, medium, difficult or expert level task and immerse yourself in the multifaceted world of numbers. Sudoku rules are intuitive in understanding, but it is not always possible to successfully apply them in practice. Especially considering that we have before us not a classic, but a slightly modified version of the puzzle.

Try to fill the empty cells of the playing field with numbers from one to nine, considering that the characters should not be repeated in each of the nine rows, columns and blocks. To add a number, just use your finger to indicate the cell, and then select the symbol located at the bottom of the screen. The field is divided into irregularly shaped areas called cages. The sum of the numbers in all cells of the cage must be equal to the value displayed in the upper left corner. The sum of the numbers in a block, row, or column is invariably forty-five.

Features:

• editing and note-taking mode;
• rewards for completing achievements;
• three themes to choose from;
• daily challenges;
• block with statistics.

If you encounter difficulties in passing the levels of intellectual entertainment Killer Sudoku, you are allowed to use hints, the number of which is limited, but the developer will kindly provide additional assistants for watching ads.
