What is Killer Sudoku and How is it Different from Regular Sudoku?
Killer sudoku is a number puzzle that combines the rules of sudoku and kakuro. The objective is to fill a 9x9 grid with numbers from 1 to 9, so that each row, column, and 3x3 box contains each number exactly once. However, unlike regular sudoku, killer sudoku also has cages, which are groups of cells separated by dotted lines. Each cage has a small number in the corner, which indicates the sum of the numbers in that cage. The numbers in each cage must add up to the given sum, and they cannot repeat within the same cage.

How to Play Killer Sudoku Online for Free
If you want to try killer sudoku without downloading anything, you can play it online for free on various websites. Here are some steps to follow:
Choose a Difficulty Level that Suits Your Skill
Most killer sudoku websites offer different difficulty levels, ranging from easy to expert. You can choose the level that matches your skill and preference. The difficulty level usually depends on the size and number of cages, as well as the availability of given numbers on the grid. The harder the level, the fewer clues you will get.
Follow the Cages and the Sums to Fill the Grid
To start playing killer sudoku online, you need to follow the cages and the sums that they indicate. Look for cages with only one cell, or cages with very low or high sums. These cages will have limited possibilities for numbers, so you can fill them easily. Then, use logic and elimination to fill the rest of the grid.
Use Logic and Strategies to Solve the Puzzles
To solve killer sudoku puzzles online, you need to use logic and strategies. One of the most useful techniques is the "45 rule", which states that each block, row, or column must contain all numbers from 1 to 9, and therefore the sum of these numbers is 45. You can use this rule to find missing numbers or eliminate possibilities. For example, if a row has a cage with a sum of 15 and another cage with a sum of 12, the remaining cells in that row must add up to 18. Another technique is to look for pairs or triples of numbers that appear in the same cages, rows, or columns. These numbers can be eliminated from other cells in the same regions. For example, if a column has two cages that both contain the numbers 3 and 4, then no other cell in that column can have 3 or 4.
