如何玩數獨
Sudoku might look tricky at first, but it’s actually a fun puzzle game anyone can enjoy. Let’s break it down step by step, how to play sudoku for beginners!
第 1 步：了解網格
Sudoku is played on a 9×9 grid, divided into nine 3×3 smaller grids. Your goal is to fill in the grid with numbers from 1 to 9, making sure that each row, column, and smaller 3×3 grid contains every number exactly once.
Step 2: Start with What’s Given
Look at the Sudoku puzzle. Some numbers are already filled in. These are your starting points. Let’s say you see a ‘5’ in a box. Check the row, column, and smaller grid it belongs to. Make sure there are no other ‘5’s in those areas.
第三步：填空
有趣的來了！ 從數字 1 到 9 開始。尋找填充較少數字的行、列或較小的網格。
Ask yourself, “What numbers are missing?” Fill in those blanks, making sure you follow the rules—no repetition in rows, columns, or 3×3 grids.
第四步：使用排除法
If you’re stuck, don’t worry. This game is about logic, not luck. If a ‘6’ can only go in one spot in a row, column, or 3×3 grid, put it there. As you fill in more numbers, it becomes easier to see where the remaining numbers should go.
第 5 步：檢查並仔細檢查
Once you think you’ve filled in the entire puzzle, take a moment to check your work. Ensure that each row, column, and 3×3 grid has the numbers 1 through 9 with no repetitions.
如何玩數獨：範例
根據提供的起始線索編號的數量，數獨謎題有不同的難度等級：
- Easy – Over 30 givens to start
- Medium – 26 to 29 givens initially filled
- Hard – 21 to 25 numbers provided initially
- Expert – Fewer than 21 pre-filled numbers
Example: Let’s walk through a medium-difficulty puzzle – an incomplete 9×9 grid:
查看整個網格和方框，掃描最初突出的任何圖案或主題。 在這裡我們看到：
- 某些列/行（例如第 3 列）已經有多個已填入的儲存格
- 某些小方框（如中右）尚未填入數字
- 記下任何可能對您解決問題有幫助的模式或感興趣的事物
接下來，有系統地檢查行和列中是否有缺少的數字 1-9，且不重複。 例如：
- 第 1 行仍需 2,4,6,7,8,9。
- 第 9 列需要 1,2,4,5,7。
Examine each 3×3 box for remaining options from 1-9 without repeats.
- 左上角的盒子仍然需要2,4,7。
- 右中框還沒有數字。
使用邏輯和演繹策略來填充單元格：
- 如果一個數字適合一行/列中的一個儲存格，請填入它。
- 如果儲存格的方塊中只剩下一個選項，請填寫它。
- 確定有希望的交叉點。
慢慢工作，仔細檢查。 在每一步之前掃描完整的拼圖。
當推導用完但單元格仍然存在時，從邏輯上猜測單元格的剩餘選項，然後繼續求解。
