Sudoku 數獨
When you play sudoku,
你玩數獨的時候，
you can only use the numbers1-9.
只能用1-9這幾個數字。
The big square or grid, is made of 9 other smaller squares, or subgrids.
大的正方形（盤面）由9個小一些的正方形（粗線宮）組成。
And those 9 subgrids have 9 smaller squaresinside them.
這些粗線宮裡有9個更小的正方形。
1 number goes in each of the smallest squares.
1個數字放在一個最小的正方形裡。
There is only one of each number in each column, row, and subgrid,
每個數字在每列、每行、每個粗線宮裡只能出現一次。
so you can't have two 9s in the same subgrid,
所以同一個粗線宮裡不能有兩個9，
or three 1s in the same row.
一行中不能有3個1。
The rest fits together like a puzzle.
剩下的就像解謎題一樣了。
