Sudoku Alternatives Explained
Killer Sudoku
Standard Sudoku rules plus dotted "cages" whose numbers must add to a given sum. No repeated digits within a cage. Adds an arithmetic layer that makes each puzzle significantly harder.
KenKen
Created by a Japanese math teacher. Grid sizes from 3x3 to 9x9 with cages that use addition, subtraction, multiplication, or division. Combines arithmetic skill with Sudoku-style placement logic.
Futoshiki
Fill a grid so each row and column has unique numbers, guided by inequality signs between cells. No boxes like Sudoku, just rows, columns, and greater-than/less-than clues.
Nonogram
Also called Picross. Number clues along the edges tell you which cells to fill in each row and column. Solving the logic reveals a hidden picture. A completely different feel from number placement puzzles.
