sudoku 玩法说明

9x9网格被分成九个3x3宫格，部分格子已预填数字作为线索。你的任务是在每个空格中填入1到9的数字，保证任何一行、一列和一个3x3宫格内的数字都不重复。首先扫描每行、每列和每个宫格，找出只有一个数字可填的格子——这叫做唯余法，是最基础的推理技巧。接下来寻找隐性唯一数：某个数字在一行、一列或一个宫格内只能放在唯一一个位置，即使那个格子还有其他候选数。利用候选数标记功能在空格中记录可能的数字。每填入一个确定数字后，重新检查相邻格子的候选数，排除已确定的数字以发现新的唯一数。中级谜题需要掌握区块排除法：当一个宫格内某个候选数只出现在一行或一列时，可以排除该行或该列中其他宫格对应的候选数。高级谜题可能需要用到显性数对、三数组或X-Wing等技巧。显性数对指同一单元中两个格子恰好共享两个候选数，该单元的其他格子中可以排除这两个数字。永远不要靠猜测解题。设计良好的数独完全可以通过逻辑推理解出每一格。如果感觉卡住了，退后一步重新审视整个网格，寻找被遗漏的约束条件。提示系统会高亮一个存在逻辑突破口的格子，帮你学习新技巧而不会直接揭示答案。

English Quick Guide

sudoku belongs to the Puzzle category and can be played directly in your browser without downloads, registration, or installation. If this is your first attempt, start with a short warm-up round and pay attention to the control rhythm before trying to chase a high score. Most players improve faster when they focus on consistency first and speed second, especially during the first few sessions.

For the best experience, use an updated browser version and keep only one active game tab while playing. If the game seems to lag, refresh once, close unnecessary background tabs, and test the same stage again. On mobile devices, landscape orientation usually provides better visibility and more accurate touch control. On desktop, a full screen window can help you react earlier to visual cues and timing changes.

A reliable strategy is to split each run into three phases: an opening phase to understand the pace, a middle phase to stabilize actions, and a late phase to reduce risky moves. When you fail, review the exact step where control broke down and retry with one concrete adjustment instead of changing everything at once. This method makes progress measurable and helps you build repeatable decision patterns.
