써모 스도쿠 플레이 방법
표준 스도쿠 규칙이 적용됩니다. 추가 규칙: 각 회색 온도계를 따라 숫자는 구근(원형 끝)에서 끝으로 갈수록 엄격히 증가해야 합니다. 3셀 온도계는 2,5,8 또는 1,4,9가 될 수 있지만 3,3,7 또는 5,4,8은 안 됩니다.

숫자는 온도계 모양을 따라 엄격하게 증가해야 합니다.
써모 스도쿠이란 무엇인가요?
Thermo Sudoku는 그리드에 온도계 모양을 겹칩니다. 각 온도계에는 한쪽 끝에 bulb(원)가 있고 다른 쪽 끝에 tip이 있습니다. 모든 온도계를 따라 digits는 bulb에서 tip으로 엄격히 증가해야 합니다. 표준 Sudoku constraints와 결합하여 이것은 강력한 추론 체인을 만듭니다 — bulb가 최소 1이고 tip이 최대 9임을 알면 위치에 따라 온도계의 각 cell에 대한 유효한 값의 범위를 계산할 수 있습니다.

써모 스도쿠 푸는 방법
| 기법 | 기능 | 레벨 |
|---|---|---|
| Range Restriction from Length | A thermometer with N cells must use N strictly increasing distinct values. The bulb is at least 1 and the tip is at most 9, giving a calculable valid range for each cell. | 고급 |
| Minimum/Maximum Bounding | The bulb value is ≤ 9 − (N − 1). The tip value is ≥ N. Apply these bounds immediately to prune all thermometer candidates. | 고급 |
| Overlapping Thermometer Deduction | Two thermometers sharing a cell give tighter combined bounds than either alone. | 고급 |
| Forcing Chains via Thermometers | When a value is forced into a thermometer cell, all cells closer to the bulb must be smaller and all closer to the tip must be larger. | 고급 |
| Short vs. Long Thermometers | A 2-cell thermometer is simply a greater-than relationship. A 9-cell thermometer forces exactly 1–9 in order. | 고급 |

자주 묻는 질문
Thermo Sudoku란 무엇인가요?
Thermo Sudoku is a variant where thermometer shapes are drawn on the grid. Each thermometer has a bulb (rounded end) and extends through several cells toward a tip. The digits must strictly increase from the bulb to the tip — so every cell along a thermometer must hold a larger digit than the one before it.
온도계 힌트를 어떻게 읽나요?
The bulb is the starting point and must hold the smallest digit on that thermometer. Each subsequent cell must be strictly larger. For example, a 3-cell thermometer starting at the bulb means the bulb holds at most 7 (since two larger digits must follow). A 5-cell thermometer means the bulb holds at most 5.
Can digits repeat on a thermometer?
No. Because digits must strictly increase, no digit can appear twice on the same thermometer. A 4-cell thermometer uses four different increasing digits. Combined with standard Sudoku uniqueness rules, thermometers create very tight constraints on every cell they pass through.
Is Thermo Sudoku hard to learn?
The core rule is simple — digits increase from bulb to tip. Beginners can start solving after understanding just that one constraint. What makes higher difficulties challenging is tracking minimum and maximum values for each thermometer cell simultaneously across many overlapping thermometers.
What is the best first move in Thermo Sudoku?
Look for long thermometers. A 7-cell thermometer can only start at 1 and end at 7, 8, or 9 — drastically limiting all seven cells. Also check for thermometers where the bulb or tip overlaps with a constrained row, column, or box, as this often pins the starting digit immediately.
How long does Thermo Sudoku take to solve?
Easy puzzles take 8–15 minutes. Medium puzzles typically run 15–30 minutes. Hard puzzles average 35–60 minutes and expert puzzles can exceed 90 minutes. The difficulty scales sharply as thermometer lengths decrease and the number of simultaneously active constraints increases.
