Games Like Sudoku

A practical guide to Sudoku alternatives, Sudoku variants and nearby logic games, with clear notes on what makes each puzzle worth trying.

If you enjoy Sudoku, the best next game usually has the same core appeal: simple rules, no-guessing deductions, a grid you can scan, and a steady feeling that one small placement unlocks the next.

This guide is built for browsing by puzzle family. Each entry explains the basic idea and why it may appeal to Sudoku players, while playable titles link naturally from the puzzle name.

Best games like Sudoku

Use the groups below to compare the main styles of Sudoku-like puzzles. Linked names are playable on this site; unlinked names are included as useful reference entries.

Closest number games like Sudoku

These are the closest games like Sudoku for players who want number placement, candidate-style scanning and a familiar grid-based solving rhythm. This group targets Sudoku alternatives such as Kakuro, Futoshiki, KenKen and Killer Sudoku: puzzles that feel nearby without simply being standard 9x9 Sudoku.

Killer Sudoku

Killer Sudoku keeps the familiar 9x9 Sudoku grid, then adds cages with sum clues. It is a good next step if you enjoy candidate scanning but want arithmetic to shape the deductions.

Kakuro

Kakuro feels like a crossword made from sums. Instead of filling rows, columns and boxes, you fill short across and down runs with digits that add to each clue without repeating.

Futoshiki

Futoshiki is a Latin-square number puzzle with greater-than and less-than signs between neighbouring cells. Sudoku players usually like it because each inequality trims candidates in a clear, local way.

KenKen

KenKen combines no-repeat rows and columns with arithmetic cages. The cages make it more calculation-heavy than Sudoku, but the solving rhythm is still about narrowing candidates step by step.

Calcudoku

Calcudoku is closely related to KenKen: rows and columns cannot repeat numbers, and cages must reach target values. It is a strong choice if you want Sudoku-like placement with more arithmetic variety.

Suko

Suko is a compact number-placement puzzle built around small regions and target totals. It is much smaller than Sudoku, but the appeal is similar: each number has to satisfy several constraints at once.

Suguru

Suguru uses irregular regions instead of boxes, and matching numbers cannot touch, even diagonally. It suits Sudoku players who like local candidate pressure and unusual region shapes.

Skyscrapers

Skyscrapers uses Latin-square rows and columns, then adds outside clues showing how many tower heights are visible from each edge. It feels Sudoku-like, but the visibility clues create a different style of deduction.

Str8ts

Str8ts asks you to place digits in white runs so each run forms a consecutive set. It has Sudoku's candidate logic, but the black cells split the grid into smaller straight segments.

Binary Puzzle

Binary Puzzle uses only 0s and 1s, but every row and column must stay balanced and avoid triples. It is lighter than Sudoku, yet still rewards scanning for forced placements.

Thermometers

Thermometers turns number logic into a visual fill puzzle. Each thermometer fills from its bulb, so row and column totals interact with directional shape constraints.

Hidato

Hidato is about building one consecutive number chain through the grid. It appeals to Sudoku solvers who enjoy using fixed givens to squeeze a path into the only remaining route.

Sudoku variants

Sudoku variants are the most direct answer when someone wants more Sudoku rather than a completely different puzzle. These games keep the core no-repeat grid but add cages, diagonals, arrows, irregular regions, extra grids or other constraints that make each variant feel fresh.

Jigsaw Sudoku / Irregular Sudoku

Jigsaw Sudoku keeps standard Sudoku row and column rules but replaces the 3x3 boxes with irregular regions. It is one of the closest variants because the rules are familiar while the region shapes change the scan pattern.

Samurai Sudoku

Samurai Sudoku overlaps several Sudoku grids into one larger puzzle. Shared areas carry information from one grid to another, so progress often comes from moving between boards.

X Sudoku / Diagonal Sudoku

X Sudoku adds the two main diagonals as extra no-repeat regions. The added lines are easy to understand, but they create long-range constraints that make ordinary Sudoku placements less automatic.

Hyper Sudoku

Hyper Sudoku adds extra highlighted regions inside the normal grid. If you like standard Sudoku but want more places where a digit can be locked, Hyper Sudoku is a natural variant.

Mini Sudoku

Mini Sudoku uses a smaller grid, often 4x4 or 6x6. It is best for quick solves, teaching the no-repeat idea, or warming up before a full 9x9 puzzle.

Wordoku

Wordoku swaps digits for letters or symbols while keeping Sudoku's no-repeat structure. The solving logic is the same, but the finished grid may reveal a word or phrase.

Arrow Sudoku

Arrow Sudoku adds arrows where the digits along the arrow must add to the circled digit. It is good for solvers who like Killer Sudoku, because sums and candidate combinations drive many early moves.

Sandwich Sudoku

Sandwich Sudoku uses outside clues that give the sum of the digits between 1 and 9 in a row or column. It keeps the standard grid but makes edge clues matter throughout the solve.

Kropki Sudoku

Kropki Sudoku marks neighbouring cells with dots for consecutive or double relationships. These small edge clues make local pairs very important, especially early in the puzzle.

Thermo Sudoku

Thermo Sudoku places thermometers inside a Sudoku grid, with digits increasing from bulb to tip. It is popular because the visual shape immediately removes many candidate orders.

Greater Than Sudoku

Greater Than Sudoku adds inequality signs between neighbouring cells. The signs give the grid a Futoshiki-like flavour while preserving the familiar Sudoku structure.

Consecutive Sudoku

Consecutive Sudoku marks or defines neighbouring cells that differ by one. The extra adjacency rule is simple, but it can sharply restrict where low and high digits belong.

XV Sudoku

XV Sudoku uses X and V marks to show neighbouring pairs that sum to 10 or 5. It is a neat arithmetic variant because every mark says something exact about two cells.

Even-Odd Sudoku

Even-Odd Sudoku marks cells by parity, usually showing where even or odd digits must go. It is one of the easiest variants to learn because the extra information divides candidates cleanly.

Anti-Knight Sudoku

Anti-Knight Sudoku forbids the same digit a chess knight's move away. The rule reaches beyond rows, columns and boxes, so spatial checking becomes part of every placement.

Anti-King Sudoku

Anti-King Sudoku forbids matching digits in diagonally touching cells. It adds a tight local restriction that makes corners of boxes and near neighbours more important.

Little Killer Sudoku

Little Killer Sudoku adds diagonal sum clues from outside the grid. It suits players who like long-range arithmetic constraints and careful combination work.

Palindrome Sudoku

Palindrome Sudoku uses marked lines that read the same from both ends. Matching positions along each line must hold the same digit, which creates elegant symmetry-based deductions.

Outside Sudoku

Outside Sudoku gives clues around the edge showing which digits appear first in each row or column. It is a good variant when you want the border of the grid to matter more.

Visual grid logic games like Sudoku

Visual grid logic games like Sudoku keep the same no-guessing deduction but replace digit placement with shading, painting, lighting, regions or hidden pictures. This section is for solvers searching for visual Sudoku alternatives, picture logic puzzles, Nonogram-style games and grid puzzles that feel logical without being number-first.

Nonogram / Picross

Nonogram replaces digits with picture logic. Row and column clues tell you which cells to fill, so the solve still feels like scanning a grid for forced placements.

Hitori

Hitori starts with a full number grid and asks you to shade repeated values until each row and column is clean. It is a nice change of pace because you remove information instead of adding it.

Nurikabe

Nurikabe is an island-and-wall puzzle where numbered islands must reach exact sizes while the shaded wall stays connected. Sudoku fans often like how each local island clue affects the whole grid.

Kuromasu

Kuromasu uses numbered cells that count how many white cells they can see horizontally and vertically. It rewards the same careful line-of-sight thinking that makes many grid puzzles satisfying.

Akari

Akari, also called Light Up, asks you to place bulbs so every white cell is lit without bulb conflicts. Numbered black cells give local counts, while light beams create long-range constraints.

Tapa

Tapa is a shading puzzle where clue numbers describe groups of shaded cells around each clue. It is more visual than Sudoku, but still relies on exact local deduction.

Norinori

Norinori asks you to shade domino pairs inside regions. The rules are compact, and the solve often comes from spotting where a two-cell shaded block can or cannot fit.

LITS

LITS uses tetromino shapes inside regions, with the shaded area forming one connected whole. It is a stronger spatial challenge than Sudoku, but still has clean rule-based eliminations.

Fillomino

Fillomino asks you to divide the grid into areas whose sizes match the numbers inside them. It is satisfying for Sudoku players who enjoy region growth and contradiction spotting.

Mosaic

Mosaic, also known as Fill-a-Pix, uses number clues to decide which nearby cells are filled. It turns deduction into a picture, making it one of the most visual Sudoku alternatives.

Yin-Yang

Yin-Yang asks you to colour every cell black or white while keeping both colours connected and avoiding solid 2x2 blocks. It is simple to learn but surprisingly strategic.

Heyawake

Heyawake is a room-based shading puzzle with rules about counts, adjacency and long white corridors. It appeals to solvers who like combining local room clues with global structure.

Cave / Bag

Cave, also called Bag, separates one connected cave from the surrounding wall. The numbered clues measure visible cave cells, so each clue controls both shape and reach.

Shakashaka

Shakashaka places black triangles around clues so the remaining white areas form rectangles. It is a good pick if you want a geometric puzzle with crisp visual deductions.

Nurimisaki

Nurimisaki is a Japanese shading puzzle built around cape-like numbered clues and white corridors. It is less widely known than Sudoku, but it belongs to the same family of precise grid logic.

Line, loop and connection puzzles

Line, loop and connection puzzles are good next steps when you enjoy Sudoku-style deduction but want the answer to be a path, loop, bridge network or set of linked endpoints. They cover route puzzles, loop puzzles and connection grid games that reward the same careful elimination Sudoku players already use.

Slitherlink

Slitherlink asks you to draw one loop around numbered cells, with each number telling how many surrounding edges are used. It is excellent if you like exact constraints but want lines instead of digits.

Masyu

Masyu is a loop puzzle with black and white pearls that control turns and straight segments. Its rules are small, but the loop logic can become wonderfully deep.

Yajilin

Yajilin combines loop drawing with shaded-cell clues. Arrows count shaded cells in a direction, and the remaining open cells must form one continuous loop.

Numberlink

Numberlink asks you to connect matching endpoints with paths that do not cross. It is more route-based than Sudoku, but still rewards thinking about forced spaces and blocked possibilities.

Hashi

Hashi, or Bridges, connects numbered islands with horizontal and vertical bridges. The numbers act like exact counts, while the final bridge network must stay connected.

Galaxies / Tentai Show

Galaxies divides the grid into rotationally symmetric regions around stars. It is a visual alternative for solvers who enjoy partitioning a board under strict shape rules.

Country Road

Country Road asks you to draw one loop through regions, usually visiting each region in a controlled way. It mixes route logic with region constraints, making it feel methodical rather than maze-like.

Arukone

Arukone is another name used for Numberlink-style endpoint connection puzzles. The challenge is to route every pair cleanly while leaving no contradictions in the remaining space.

Placement and region puzzles

Placement and region puzzles are Sudoku-like logic games where the main decision is where objects, shapes, regions or ships can legally go. They are useful alternatives for people searching for constraint puzzles like Sudoku, spatial logic games, region-based puzzles and object-placement grid games.

Tents and Trees

Tents and Trees asks you to place one tent beside each tree while matching row and column totals. It is one of the friendliest placement puzzles for Sudoku players because every clue narrows a small set of cells.

Star Battle

Star Battle places stars in rows, columns and regions without letting them touch. It feels Sudoku-like because every placement affects several overlapping constraints at once.

Queens

Queens uses chess-queen style placement ideas on a coloured region grid. It is approachable, but good puzzles still demand careful elimination across rows, columns and regions.

Shikaku

Shikaku divides the grid into rectangles, each containing one number equal to its area. It is calm and spatial, with deductions based on which rectangle sizes can still fit.

Battleship

Battleship is a fleet-placement puzzle with row and column counts. The no-touching ship rule gives it a Sudoku-like rhythm of marking impossible cells and confirming forced ones.

Ripple Effect / Hakyuu

Ripple Effect fills rooms with numbers while enforcing distance rules between equal values. It is a strong Sudoku alternative for players who like region logic and candidate spacing.

Tatamibari

Tatamibari divides the grid into rectangles based on clue symbols. It is a quiet spatial puzzle where each clue limits the orientation and shape of its room.

Minesweeper

Minesweeper is not usually described as a Sudoku relative, but its best moments are pure deduction. Each number limits nearby hidden cells, and safe progress comes from combining overlapping clues.

Latin Squares

Latin Squares are the mathematical core behind Sudoku: each symbol appears once in every row and column. Without boxes, the puzzle becomes a cleaner study of row-column placement logic.

Sudoku variants to try

If you want something that still feels like Sudoku, start with the variant group. If you want a bigger change, try Kakuro, Futoshiki, KenKen, Nonogram, Akari, Slitherlink or Star Battle.

How to choose a Sudoku alternative
