Sudoku is one of the most loved logic puzzles worldwide, known for its grid-based format and requirement for critical thinking. If you enjoy Sudoku but want to try other games that offer similar challenges, there are many logic and number-based puzzles to explore. These puzzles test your reasoning, patience, and problem-solving skills in unique ways.
Here is a list of puzzles similar to Sudoku that you can try for a fresh challenge while keeping the fun and brain workout alive.
Kakuro
What It Is:
Kakuro combines Sudoku and crossword-style puzzles. Players fill in numbers on a grid so that they add up to specific sums.
How to Play:
- The grid consists of white and black cells.
- Numbers must be placed in white cells.
- Each “across” or “down” section has a given sum, and no number can repeat in that section.
Why It’s Like Sudoku:
Kakuro requires logical deduction and number placement without repetition, just like Sudoku.
KenKen
What It Is:
KenKen, sometimes called “MathDoku,” is a grid-based puzzle involving numbers and arithmetic operations.
How to Play:
- Fill the grid with numbers (e.g., 1-4 in a 4×4 grid) without repeating numbers in rows or columns.
- Some cells are grouped into “cages” with a target number and an arithmetic operation (e.g., addition, multiplication).
- Numbers in the cage must satisfy the arithmetic condition.
Why It’s Like Sudoku:
KenKen uses grids, logical reasoning, and number placement without repetition, adding a math twist to the challenge.
Nonogram (Picross)
What It Is:
Nonogram, also called Picross or Griddlers, is a picture logic puzzle where you fill cells to create an image based on numerical clues.
How to Play:
- The grid has numbers along the rows and columns that indicate how many cells should be filled.
- Using deduction, players determine which cells to fill and which to leave blank.
Why It’s Like Sudoku:
Both puzzles require logical thinking, deduction, and pattern recognition, with a satisfying solution at the end.
Hitori
What It Is:
Hitori is a logic puzzle where players eliminate duplicate numbers in a grid to meet specific conditions.
How to Play:
- Start with a grid filled with numbers.
- Eliminate (shade) duplicate numbers so that no row or column has repeating numbers.
- Shaded cells cannot touch each other horizontally or vertically.
Why It’s Like Sudoku:
Hitori challenges you to eliminate duplicates, similar to Sudoku’s number-placement rule.
Futoshiki
What It Is:
Futoshiki, also known as “Unequal,” is a grid-based puzzle where players fill numbers while respecting inequality signs.
How to Play:
- Fill the grid with numbers (e.g., 1-5 for a 5×5 grid).
- Numbers cannot repeat in any row or column.
- Inequality signs between cells (e.g., “>” or “<”) indicate relationships between adjacent numbers.
Why It’s Like Sudoku:
Futoshiki follows the same grid logic and no-repetition rule, with an added layer of inequalities for extra challenge.
Killer Sudoku
What It Is:
Killer Sudoku is a variation of Sudoku that combines traditional Sudoku with math-based challenges.
How to Play:
- Fill a Sudoku grid with numbers 1-9.
- The grid contains “cages” with a target sum. Numbers within a cage must add up to the target.
- Numbers cannot repeat in rows, columns, or cages.
Why It’s Like Sudoku:
Killer Sudoku retains the original Sudoku grid rules while introducing math for added complexity.
Hashi (Bridges)
What It Is:
Hashi, also called Bridges, is a logic puzzle where you connect islands using “bridges” based on numerical clues.
How to Play:
- The grid has islands represented by circles with numbers.
- Numbers indicate how many bridges connect to that island.
- Bridges cannot cross each other, and all islands must be interconnected.
Why It’s Like Sudoku:
Hashi requires logical thinking, careful planning, and elimination strategies, much like Sudoku.
Slitherlink
What It Is:
Slitherlink is a puzzle where players draw a single, continuous loop around a grid while following numerical clues.
How to Play:
- Numbers in the grid indicate how many sides of a square must have part of the loop.
- The loop cannot cross itself or split into separate parts.
Why It’s Like Sudoku:
Slitherlink demands logical deduction and visualization, similar to how players solve Sudoku grids.
Numbrix
What It Is:
Numbrix is a sequential number puzzle where players fill a grid with numbers in order.
How to Play:
- Start with a partially filled grid.
- Fill in the remaining numbers so they form a continuous sequence.
- Numbers must move horizontally or vertically (not diagonally).
Why It’s Like Sudoku:
Both puzzles require logical deduction and filling grids in an orderly manner.
Takuzu (Binary Puzzle)
What It Is:
Takuzu, or Binary Puzzle, involves placing 0s and 1s into a grid while following strict rules.
How to Play:
- Fill a grid with 0s and 1s.
- No more than two identical numbers can appear consecutively in any row or column.
- Rows and columns must have an equal number of 0s and 1s.
Why It’s Like Sudoku:
Takuzu uses grid-based logic and elimination rules similar to Sudoku.
Samurai Sudoku
What It Is:
Samurai Sudoku is an advanced variation of Sudoku featuring five overlapping Sudoku grids.
How to Play:
- Follow traditional Sudoku rules, filling each grid with numbers 1-9.
- The overlapping sections must satisfy the rules for all connected grids.
Why It’s Like Sudoku:
It’s a challenging extension of the classic Sudoku puzzle, designed for advanced players.
