Chess Sudoku

Chess Sudoku is a unique puzzle game that blends the classic rules of Sudoku with chess-inspired twists, created by the hosts of the popular YouTube channel Cracking The Cryptic. The game features three variants—Knight Sudoku, King Sudoku, and Queen Sudoku—each introducing chess-based constraints to traditional Sudoku logic. In Knight Sudoku, digits cannot repeat within a knight’s move, while King Sudoku restricts diagonal adjacency, and Queen Sudoku treats every ‘9’ as a chess queen, blocking rows, columns, and diagonals. With handcrafted hints and a progressive difficulty system, players earn stars by solving puzzles, unlocking more challenges as they improve their skills.

This review will delve into the game’s development history, narrative and thematic elements, gameplay mechanics, artistic and auditory design, reception, and legacy, ultimately arguing that Chess Sudoku is a standout title in the puzzle genre, offering a unique blend of accessibility and depth.

Development History & Context

The Studio and Creators’ Vision

Studio Goya, the developer behind Chess Sudoku, is a relatively small but ambitious studio known for its focus on puzzle games. The studio’s collaboration with Simon Anthony and Mark Goodliffe, the hosts of the popular YouTube channel Cracking The Cryptic, was a stroke of genius. Anthony and Goodliffe are renowned figures in the Sudoku community, having represented the UK multiple times at the World Sudoku Championship. Their involvement ensured that Chess Sudoku was not just another puzzle game but a meticulously crafted experience designed to challenge and educate players.

The vision behind Chess Sudoku was to create a game that combined the strategic depth of chess with the logical rigor of Sudoku. The developers aimed to create a game that was both accessible to newcomers and challenging enough to engage seasoned puzzle enthusiasts. This vision is evident in the game’s design, which features a gradual difficulty curve and a variety of puzzle types that cater to different skill levels.

Technological Constraints and the Gaming Landscape

Released in 2020, Chess Sudoku benefited from the technological advancements of the time. The game was developed using the Unity engine, which allowed for a smooth and responsive user interface. The use of FMOD for sound design ensured that the game’s auditory elements were crisp and immersive.

The gaming landscape in 2020 was dominated by high-budget AAA titles and competitive multiplayer games. In this context, Chess Sudoku stood out as a niche, single-player puzzle game. Its release on Steam, a platform known for its diverse library of indie games, was a strategic move that allowed it to reach a broad audience of puzzle enthusiasts.

Narrative & Thematic Deep Dive

Plot and Characters

Chess Sudoku does not feature a traditional narrative or characters in the conventional sense. Instead, the game’s “story” is told through its puzzles and the progression system. Players start with zero stars and earn stars by solving puzzles, unlocking more challenging puzzles as they progress. This progression system serves as a narrative arc, guiding players from simple puzzles to more complex ones, and ultimately to the most challenging puzzles in the game.

The hosts of Cracking The Cryptic, Simon Anthony and Mark Goodliffe, serve as the game’s de facto characters. Their presence is felt through the hints and tips they provide, which are designed to help players improve their puzzle-solving skills. Their involvement adds a personal touch to the game, making it feel like a collaborative effort between the developers and the players.

Dialogue and Underlying Themes

While Chess Sudoku lacks traditional dialogue, the hints and tips provided by Anthony and Goodliffe serve as a form of communication between the game and the player. These hints are not just mechanical instructions but are crafted to teach players how to approach puzzles more effectively. This educational aspect is a recurring theme in the game, reflecting the developers’ commitment to helping players improve their skills.

The underlying theme of Chess Sudoku is the fusion of logic and strategy. The game challenges players to think not just about the immediate placement of numbers but also about the broader implications of their moves. This theme is reinforced by the game’s chess-inspired mechanics, which require players to consider the strategic implications of their actions.

Gameplay Mechanics & Systems

Core Gameplay Loops

The core gameplay loop of Chess Sudoku revolves around solving puzzles. Players are presented with a grid and must fill in the numbers according to the rules of Sudoku, with additional constraints based on chess moves. The game features three main types of puzzles: Knight Sudoku, King Sudoku, and Queen Sudoku.

• Knight Sudoku: In addition to the standard Sudoku rules, a digit must not appear a chess knight’s move away from itself. This restriction introduces additional logic that makes the puzzles more interesting and challenging.
• King Sudoku: Similar to Knight Sudoku, but with the restriction that a digit must not be a single diagonal move away from itself.
• Queen Sudoku: Every 9 in the grid acts like a chess Queen and must not be in the same row, column, 3×3 box, or diagonal of any other 9.

These variations add depth to the gameplay, ensuring that players are constantly challenged and engaged.

Combat and Character Progression

Chess Sudoku does not feature traditional combat or character progression systems. Instead, the game’s progression is tied to the player’s ability to solve puzzles. As players solve more puzzles, they earn stars, which unlock more challenging puzzles. This system ensures that players are constantly motivated to improve their skills and tackle more difficult puzzles.

UI and Innovative Systems

The user interface of Chess Sudoku is clean and intuitive, designed to minimize distractions and allow players to focus on the puzzles. The game features a point-and-select interface, which is well-suited to the puzzle-solving mechanics. The hints provided by Anthony and Goodliffe are integrated seamlessly into the UI, ensuring that players can access them easily without breaking their flow.

One of the most innovative aspects of Chess Sudoku is its hint system. Unlike many puzzle games that provide generic hints, the hints in Chess Sudoku are crafted by Anthony and Goodliffe, ensuring that they are both helpful and educational. This system not only helps players solve puzzles but also teaches them how to approach similar puzzles in the future.

World-Building, Art & Sound

Setting and Atmosphere

Visual Direction

The use of color is minimal, with a focus on contrast and readability. This design choice ensures that the game is accessible to players of all ages and skill levels.

Sound Design

The sound design of Chess Sudoku is subtle but effective. The game features a soft, ambient soundtrack that helps to create a relaxing atmosphere. The sound effects are minimal, with a focus on providing feedback to the player. For example, the sound of a number being placed correctly is distinct and satisfying, while the sound of an incorrect placement is subtle but noticeable. This design choice ensures that the sound design enhances the gameplay experience without being intrusive.
