Medium Killer Sudoku Puzzles
Step up your game with these medium Killer Sudoku puzzles. With an intermediate difficulty, these number puzzles will introduce players to the real challenges of Killer Sudoku and why they can be even more addictive than the original Sudoku games.
At this difficulty stage, the solution and possibilities for each cage are not as obvious as in the easy puzzles. The player must already consider other variables and employ logical reasoning to deduce which numbers are viable or correct for each cell.
Medium Killer Sudoku techniques: cage combinations
Cage combinations are a key feature of online Killer Sudoku puzzles with a medium difficulty level. These are not a technique or a solving strategy per se, but rather a shortcut to make analyzing the grid and deducting possible solutions more straightforward.
They serve as a helping method to keep the notes on the grid tidy and to work by a process of elimination. For example, a cage with four cells and the sum of 10 can only contain the numbers 1, 2, 3, and 4. This is the only combination possible under the no-repetition rule. Depending on the position of the said cage, the players can put a process of elimination in action and eliminate those digits as possible solutions to other cells in the same row, group, or columns, for example.
The most common cage combinations on this difficulty level are:
2-cell cages
3 = 1, 2
4 = 1, 3
16 = 7, 9
17 = 8, 9
3-cell cages:
6 = 1, 2, 3
7 = 1, 2, 4
23 = 6, 8, 9
24 = 7, 8, 9
4-cell cages:
10= 1, 2, 3, 4
11 = 1, 2, 3, 5
29 = 5, 7, 8, 9
30 = 6, 7, 8, 9
