Of the sudokus from the Cracking the Cryptic collection this is probably my favorite. I personally get more enjoyment out of the anti-knight rule for sudoku but I found myself getting a lot of enjoyment out of these sudokus. They also have a nice ramping difficulty where you can slowly learn the logic and spot things. I think the main reason I love this one more than the Chess collection is that there were more puzzles I enjoyed a lot and the last puzzle was one I was incredibly proud of myself for figuring out without using any hints. It also has some very beautiful logic. I felt like with my mediocre skills I was able to approach and appreciate the genius that you can see displayed by the Cracking the Cryptic solvers all the time.
Arguably one of the easier sudoku variants - even if you struggle at hard/expert level stanadrd sudoku puzzles, the logic behind thermometer sudoku makes for some really engaging yet approachable solves. Also CTC are awesome and you should absolutely buy the entire CTC bundle!
Thermo Sudoku, developed and published by Studio Goya, is a carefully crafted logic puzzle experience that builds upon the familiar structure of Sudoku while introducing a single, well-conceived twist that significantly deepens the challenge. Rather than overcomplicating the formula with multiple mechanics, it focuses on the concept of thermometers—visual paths within the grid where numbers must increase from one end to the other—and uses this idea as the foundation for its entire design. The result is a game that feels intuitive at first glance but gradually reveals a surprising level of depth as players engage with its puzzles. The traditional rules of Sudoku remain intact, requiring players to fill a 9×9 grid with numbers from 1 to 9 without repetition across rows, columns, and subgrids. What changes is how these numbers are placed in relation to the thermometers embedded in the puzzle. Each thermometer enforces a strict ascending order, meaning that numbers must increase step by step along its path. This seemingly simple addition transforms the way players approach the grid, as every placement must now satisfy both the standard rules and the directional constraints imposed by the thermometers. It encourages a more holistic style of thinking, where the position of one number can influence multiple areas of the puzzle simultaneously. What makes this system particularly effective is how naturally it integrates into the solving process. The thermometers act as both constraints and visual guides, shaping the flow of logic across the grid. Early puzzles use straightforward thermo placements to introduce the concept, allowing players to become comfortable with the mechanic. As the game progresses, however, the layouts become more intricate, with overlapping and intersecting thermometers that create increasingly complex scenarios. This evolution keeps the experience engaging, as players are constantly challenged to adapt their strategies and consider new patterns of deduction. The quality of the puzzle design is a standout feature. Each puzzle is handcrafted, ensuring that every challenge has a clear logical path rather than relying on guesswork. The progression is carefully balanced, gradually increasing in difficulty while introducing more sophisticated problem-solving techniques. This structure makes the game accessible to newcomers while still offering substantial depth for experienced players. The sense of progression is tangible, as players move from basic deductions to more advanced reasoning, building confidence and skill along the way. An important aspect of this progression is the game’s approach to guidance. The hint system is designed not to provide direct answers but to explain the reasoning behind specific steps. This encourages players to learn and understand the logic rather than simply completing puzzles through trial and error. It adds an educational dimension to the experience, making it particularly appealing for those who enjoy improving their analytical skills. Over time, players begin to recognize patterns more quickly and approach puzzles with greater efficiency. Visually, Thermo Sudoku adopts a clean and minimalistic interface that prioritizes clarity and ease of use. The grid is easy to read, controls are responsive, and tools for note-taking and number entry are implemented smoothly. This simplicity ensures that the focus remains on the puzzle itself, without unnecessary distractions. While the presentation is understated, it is effective in supporting the gameplay, allowing even complex puzzles to remain manageable. In terms of content, the game offers a solid range of puzzles that vary in difficulty, providing a substantial experience for those who enjoy logic challenges. However, its focus on a single core mechanic also defines its limitations. There are no additional modes or variations to diversify the experience, and players who are not deeply invested in Sudoku-style puzzles may find the gameplay repetitive over time. Additionally, the later puzzles can become quite demanding, requiring patience and a willingness to engage with more advanced techniques, which may not appeal to all players. Despite these constraints, Thermo Sudoku succeeds by delivering a focused and well-executed experience that builds depth from simplicity. It demonstrates how a single, thoughtfully implemented idea can transform a classic formula into something fresh and engaging. For players who appreciate logical problem-solving and enjoy gradually mastering complex systems, it offers a rewarding and intellectually satisfying journey. Rating: 8/10
I'm very bad at sudoku. In any case, this is a lot of fun, and I find myself missing its interface when playing sudoku through other apps. The hand-crafted puzzles are definitely noticeable; if you've only played with generic collections or randomly generated puzzles, don't disregard the value of human-made sudokus.
Grande questa versione del Sudoku!!! Stavolta c'è la variante del termometro che lo rende molto interessante! Bellissimo gioco come sempre! Questa serie di giochi è davvero ben fatta! Fiero di aver acquistato tutto il pacchetto di 7!
very good sudoku game

Fun variation on Sudoku. Good value for money
Fun and good Sudoku game, the thermo restrictions do add a fun and different element that makes you think a bit harder. The interface is good once you get used to it but it would be nice to have music and sounds. The hints and smart hints and useful, if you use them to understand why the hint is given, you can really boost your sudoku skill. However, it's very difficult if you're somewhat new to sudoku's so it would require knowledge of at least a few techniques... x/y wings, snyder notes, naked singles etc otherwise I think you may struggle to even get started on the easiest ones.
