Evaluating Creative Reasoning with Sudoku Variants

This leaderboard shows performance on the Sudoku-Bench reasoning evaluation dataset.

Sudoku variants are not like vanilla Sudoku puzzles — Each puzzle author invents new rules specific to that puzzle (scroll down to see examples). These human-crafted puzzles are designed to stump expert solvers at first glance, but allow progress once the solver finds a non-obvious “break-in.” As such, Sudoku variants are the ideal (and possibly densest) source of “aha” or “euraka” moments in creative problem solving.

This makes Sudoku variants one of the most high-signal domains for benchmarking LLM reasoning models. We find that most LLMs struggle to make progress on most variant puzzles.

Sudoku-Bench is intended to evaluate LLM reasoning models without tool use. Humans can solve these puzzles by finding a creative insight that leads to a “break-in.” This means that humans can solve these in a “token-efficient” manner, but only after discovering some creative insight about the particular puzzle. We thus test LLMs to do the same and in all evaluations below we disable tool use.

Please see our technical report for an introduction to Sudoku variants and their utility in AI reasoning research.

Sudoku-Bench Leaderboard

(Note: A ‘-’ indicates insufficient data to meet reporting thresholds due to cost limitations.)

Models are evaluated using one of two configurations:

• Single-Shot: The LLM attempts to solve the entire puzzle grid in one response.
• Multi-Step: The LLM is prompted to provide one or more cell placements in each turn. The user displays the updated board. The interaction continues until the LLM solves the puzzle or makes an incorrect move.

The evaluation measures performance based on two primary metrics:

• Average Solve Rate (ASR): The percentage of puzzles for which the model produces the complete and correct final solution grid. This is the primary metric for overall success.
• Average Correct Placements (ACP) for Multi-Step Mode: The average number of correct cell values placed before the puzzle is solved, an incorrect placement is made, or another termination condition (such as an API error or reaching a maximum number of steps) occurs.

The benchmark includes 100 puzzles of different grid sizes (15 4x4, 15 6x6, 70 9x9).

Frequently Asked Questions

Is there a private test set?

Due to the significant investment human setters make in crafting each puzzle, we do not have a private test set. The current Sudoku-Bench represents a curated snapshot of existing puzzles created before 2025. We may consider a private test set in the future.

Dozens of high-quality Sudoku variants are published daily on the web so any puzzle after an LLM’s training cutoff date can be considered out-of-domain if one wishes to test on them.

How is Sudoku-Bench different from other LLM reasoning benchmarks?

At its core, Sudoku-Bench is meant to measure the “aha” or “eureka” moment from creative problem-solving. Sudoku variants may be the densest source of eureka moments available, since puzzle authors explicitly design their puzzles to be seemingly unbreakable at first glance — even to expert solvers who have years of experience — but admit progress after a creative discovery is made.

Such insights are difficult to find in standard benchmarks, since a domain can be readily mastered through enough training data. But Sudoku variants are constantly evolving. Each Sudoku variant puzzle is unique — either through a unique ruleset or by requiring a solving tactic never seen before — making the domain of Sudoku variants more resistant to memorization compared to other benchmarks.

The memorization-resistance is similar in spirit to the ARC-AGI benchmark. A difference between ARC-AGI and Sudoku-Bench is worth noting: ARC-AGI puzzles ask the solver to discover the puzzle constraints by presenting a few examples, after which execution is often straightforward. In a Sudoku variant, all constraints are explicitly given as part of the puzzle, but a direct application of each rule in isolation typically yields no progress — a creative process is required to see how the constraints interact in non-obvious ways to create intermediate results, and ultimately a break-in to the solution. This makes Sudoku variants more similar to ARC-AGI-2 which emphasizes compositional reasoning.

Is Sudoku-Bench only for LLMs?

Mostly, yes.

Puzzles from ARC-AGI or standard (non-variant) Sudoku puzzles have a universal tokenized representation that applies to all training and test samples. However, Sudoku variants are so varied that we need natural language to encode and represent each puzzle. Sudoku-Bench in its current form is best suited for benchmarking LLM reasoning models.

Sudoku variants are not suitable for certain non-LLM reasoning models (e.g., HRM or TRM) without an explicit LLM module of some kind.

We present text-only representations of all puzzles in Sudoku-Bench. However, the dataset is naturally applicable for VLMs as well, which may be required for certain puzzles whose visual elements are too complex to fit into text. We explicitly selected the 100 puzzles of Sudoku-Bench to be ones that admit a text-only representation.

Example Prompt

You are a professional Sudoku puzzle solver. Please solve the following Sudoku variant.

## Format Explanation ##
Coordinates:
- We will use r{x}c{y} coordinates. For example, r1c1 is the top-left cell at row 1 column 1, r1c2 is the cell to the right at row 1 column 2, r2c1 is the cell below at row 2 column 1, and so on.

Visual Elements:
- Any visual elements will be described in text using rxcy coordinates.
- Please note the visual elements will be described as-is. If a thermo or arrow appears on the board, the location of the circle or bulb will be listed, and the line or arrow will be listed as a separate object. But you can infer they are part of the same object by their coordinates.
- If a visual element is described as "between" two cells, it means the visual element appears on the edge between the two cells.
- In some puzzles there may be visual elements outside of the grid and these will be described using the same coordinate system. For example an arrow in r0c1 pointing to the lower right means there is an arrow above r1c1 that points in the direction of the diagonal: r1c2, r2c3, etc.

## Tips ##
- In solving the puzzle it often helps to understand that there exists a unique solution.
- It therefore helps to focus on what values must be forced given the puzzle constraints, and given the fact that the solution is unique.
- All information is provided and is sufficient to solve the puzzle.

Initial Board:

.................................................................................

Rules:

Normal sudoku rules apply. Identify two 'indexer' cells in each row, column, and box, with one indexing in the row and the other indexing in the column. The digit in an indexer cell indicates the position of the other indexer cell in its row or column. Positions are counted left to right in rows and top to bottom in columns. The value of an indexer cell is the digit in the cell it indexes. For all other cells, their value is their own digit. All lines are region-subset lines: ie 3x3 box boundaries divide each line into segments. For any pair of segments on the same line, the values on one of those segments must all appear on the other segment. Examples: i) If () represents an indexer cell, then 12(6)34(7)598 would be a valid row of digits, because there are exactly two indexer cells, and one of the cells indexes the other: the (7) is in position 6, and the other indexer cell contains a 6. The value of the (6) cell would be 7, because that is the digit in the cell it indexes. Given that this is a row, we would also know that r7c6 must be an indexer cell, because the (7) cell indexes it. ii) A region-subset line could contain the values 189-8-98-918, where a dash represents a box boundary. This is valid because (8) is a subset of (89) and (189), (89) is a subset of (189), and (189) is a subset of itself.

Dyscalculia

Initial Board:

.................................................................................

Rules:

I’m just so terrible with numbers! Whenever I try to write anything down, it always ends up full of obvious numerical errors. That simply won’t do in a sudoku, so I decided that I needed help. I shared this puzzle with my very punctilious friends, who made sure that all of the clues were correct. However, they weren’t able to say the same about the rules. After reading them very carefully, they assure me that I have, somehow, at least managed to stay consistent in the amount of my mistakes. That, along with normal sudoku rules should be enough information for you to solve it. (Make sure you scroll to see them all, unlike one of the testers who was left utterly confused). Here they are:

Cells separated by a V contain digits that add up to 5, and those separated by an X contain digits that add up to 7.

The numbers outside the grid are Sandwich Sums, which indicate the sum of the digits between 8 and 9 in the corresponding row or column.

Digits inside Killer Cages cannot repeat, and must add up to the total indicated in the upper left corner of the cage, or perhaps the total minus one (I can’t be sure, I’m terrible with numbers! But I’m consistent, so whichever it is, it’s the same for all four cages).

Three adjacent digits on a German whisper line must have a difference of at least 5.

All rules contain numerical mistakes, exactly two per rule.

Matty Didn't Call You Back Because He Had The Wrogn Number

by Lake

Initial Board:

.................................................................................

Rules:

Normal sudoku rules apply.

Every clue in the puzzle is wrogn. A clue is wrogn if it is not completely correct.

Killer Cages: Digits in a cage cannot repeat and sum to the digit in the top left corner of the cage.

Look-And-Say Cages: Cages are also, independently, look-and-say. The number in the top left corner also says how many of each digit are in the cage. E.g. there is exactly "one 1" in the cages in box 2.

Arrows: A digit in a circle with an arrow attached is equal to the sum of the digits on the attached arrow. The different colours don't mean anything different.

Renban: digits on a purple renban line form a non-repeating set of consecutive digits, in any order.

Nabner: The set of digits on an orange nabner line must not repeat and no two digits on the line may be consecutive.

German whisper: Adjacent digits along a green german whisper line must have a difference of at least 5

Kropki dots: Digits separated by a white kropki dot are consecutive, digits separated by a black kropki dot are in a 1:2 ratio.

Thermos: Digits along a thermometer must always increase from the bulb to the tip.

The clues outside the grid are all independently Numbered Rooms, Sandwich and Skyscraper clues.

Numbered Rooms: A clue outside the grid indicates the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.

Sandwich: The numbers outside the grid give the sum of the digits between the 1 and the 9 in that row or column.

Skyscrapers: Digits in the grid represent skyscrapers, with their values corresponding to their heights. Taller skyscrapers obscure all shorter skyscrapers behind them. Clues outside the grid indicate the number of skyscrapers that can be seen in that row/column, from the line of sight of the clue.

Loopy Whisper Rooms

by yttrio

Initial Board:

.................................................................................

Rules:

Normal Sudoku rules apply.

Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.

The loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5).

Loopy Numbered Rooms: Clues outside the grid indicate the digit which has to be placed in the Nth loop cell in the corresponding direction, where N is the digit next to the clue (and not necessarily on the loop).

Negative Arrows

by damo_89

Initial Board:

........................................................7........................

Rules:

Normal sudoku rules apply

Arrows: Values on an arrow sum to the value in the arrow's circle

XV: Values on an X sum to 10. Values on a V sum to 5. Not all XV are necessarily given.

Negators: There are 9 cells in the grid which are negators, one each in every row, column and 3x3 box, containing the digits 1 to 9 once each. Digits in a negator cell count as negative for the purposes of arrows and XV. E.g. a valid arrow could be 8 = 5 + 7 + (-4) if the 4 were in a negator cell.

Tropical Knights

by Jolly Rogers

Initial Board:

.................................................................................

Rules:

Normal Sudoku rules apply.
A digit in a circle must belong to the same entropic group (high [789], medium [456] or low [123]) as every cell a single chess knights move away from it.
Digits on a purple renban line are consecutive and non-repeating.
Adjacent digits along a green whisper line must differ in value by at least 5.
The digits joined by a black dot must be in a 2:1 ratio, e.g one digit is double the other.

Guess Who?

by pep9

Initial Board:

....................................

Rules:

Normal 6x6 sudoku rules apply. In the grid, there are 6 grey lines. Each grey line is either a German whisper (adjacent digits must differ by at least 3), a region sum line (digits must have an equal sum within each region it passes through), or a renban (consists of a set of (non-repeating) consecutive digits). The solver has to determine the nature of each line. However, there are exactly 2 lines of each type.

Moving Day?

by ThePedallingPianist

Initial Board:

....................................

Rules:

Select six different digits from the set 1-9.  Use these six digits only to fill every cell such that a digit does not repeat in a row, column or box. Grey lines are entropic AND modular; i.e every 3-cell sequence on a line must contain a digit from {123}, one from {456} and {789}; also these digits must include one from {147}, one from {258} and one from {369}. Both indicated diagonals have the same sum. The inequality sign ‘points' to the lower digit. Any 5 in the grid must have a 1 directly above it or a 9 directly below it (or both).

Normal Sudoku rules apply (place the digits 1-9 once each in every box, row and column)

Around Quad clues (white circles with digits in) each digit that appears must appear at least once in the cells that the quad touches.

Green Lines are both German Whispers AND palindromes.

For German Whispers each consequtive digit must differ by a value of at least 5. For palindromes the lines must read the same in both directions (for example 1234321)

The white dot must contain consequtive digits in the two cells it touches.

by sujoyku

Initial Board:

.................................................................................

Rules:

- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.

- Index lines: Each turquoise line is an Index Line, i.e. the digit in the Nth cell along such a line (starting from the diamond) indicates the position along the line where the digit N appears. For example, if a diamond cell contains a 3, the third cell along that line must have a 1.

- German Whispers: Adjacent digits along a green line must differ by at least 5.

- Renban: Each purple line must contain a set of consecutive non-repeating digits in any order.

You are a professional Sudoku puzzle solver. Please solve the following Sudoku variant.

## Size ##
9 x 9

## Rules ##
"- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.\n\n- Index lines: Each turquoise line is an Index Line, i.e. the digit in the Nth cell along such a line (starting from the diamond) indicates the position along the line where the digit N appears. For example, if a diamond cell contains a 3, the third cell along that line must have a 1.\n\n- German Whispers: Adjacent digits along a green line must differ by at least 5.\n\n- Renban: Each purple line must contain a set of consecutive non-repeating digits in any order."

Nosferatu Crossfire

by Mad-Tyas

Initial Board:

.................................................................................

Rules:

Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.

Nosferatu: Nine cells in the grid are Nosferatu cells. They have to be filled with one complete set of the digits from 1-9. Each row, column and marked 3x3 box contains exactly one Nosferatu cell.
There also are nine Prey cells following the same rules as the Nosferatu cells. A cell can only have one of these roles.
The values of all Prey cells are 0. The value of a Nosferatu cell is the sum of the digits in the Nosferatu cell and the Prey cell in the same marked 3x3 box.

Arrow: The values along an arrow have to add up to the value in the attached circle.

Rules:

• Divide the grid into 9 kingdoms of orthogonally connected cells. Fill the grid with the digits 1-9 so that digits don't repeat in a row, column or kingdom.
• A digit in a blue square indicates its kingdom's strength. Each kingdom has a different strength, which is determined by summing the digits in its castle(s).
• Digits connected by bridges are in different kingdoms and for each their value is the strength of the kingdom on the other side of the bridge. Two kingdom borders are provided.

by bad_fetus

Initial Board:

................

Rules:

Normal 4x4 Sudoku rules do NOT apply.

- Digits may not repeat in a column.
- Digits may not repeat in a row.
- Digits may not repeat in a box.

Error sudoku: Input the digits 1 to 4 on the grid exactly four times each. You must make exactly N total errors for each digit, where N is equal to the digit. For example, you must make exactly 3 errors with the digit 3. Only the rules marked with a dash may be violated for this purpose.

Any time a pair of digits violates any of the relevant rules, it counts as 1 error. One pair can cause multiple errors if it violates multiple rules simultaneously. For cases involving more than 2 digits, all combinations of pairs count individually.

Row/Column sums: The values outside the grid restrict the sum of the digits on that row/column.

Palindrome: The digits on the lines read the same backwards and forwards.

Twelve Spots

by Marty Sears

Initial Board:

....................................

Rules:

Normal 6x6 sudoku rules apply.

Draw 6 lines, each with a different turquoise spot at both ends. Each line must occupy at least 3 cells, and may move orthogonally and diagonally. Lines may not branch, cross each other, or share cells.

Each line is a 'same difference' line. Every pair of adjacent cells along a line has the same difference - this is its 'difference value.'

Every line has a different 'difference value'.

Digits in a cage sum to the total in the corner.

Visual Elements:
