刚学完数组和字典后尝试的，当时听群友说运用递归才好，可还没有学到递归，所以想到的方法比较简单。在这个基础上还可以加上其它的求解数独办法，至少可以求解简单级别的数独，但是中级往上的数独应该就要用假设赋值才行，这个一时还没有想到

Sub as1()
Set d = CreateObject(“scripting.dictionary”)
‘On Error Resume Next
a = 0
b = 0
For x = 1 To 9

 For y = 1 To 9
 
  For sz = 1 To 9 ‘若空，则同行列进字典
  
  If Cells(x, y) = “” Then
  d(Cells(sz, y).Value) = Cells(sz, y).Value: d(Cells(x, sz).Value) = Cells(x, sz).Value: d(0) = 0
  Else:
  GoTo 1
  End If
  Next sz
   For a = 0 To 6 Step 3 ‘同9宫格内的内容进字典
   For b = 0 To 6 Step 3
   If a < x And x < a + 4 And b < y And y < b + 4 Then
   d(Cells(1 + a, 1 + b).Value) = Cells(1 + a, 1 + b).Value: d(Cells(1 + a, 2 + b).Value) = Cells(1 + a, 2 + b).Value: d(Cells(1 + a, 3 + b).Value) = Cells(1 + a, 3 + b).Value: d(Cells(2 + a, 1 + b).Value) = Cells(2 + a, 1 + b).Value: d(Cells(2 + a, 2 + b).Value) = Cells(2 + a, 2 + b).Value: d(Cells(2 + a, 3 + b).Value) = Cells(2 + a, 3 + b).Value: d(Cells(3 + a, 1 + b).Value) = Cells(3 + a, 1 + b).Value: d(Cells(3 + a, 2 + b).Value) = Cells(3 + a, 2 + b).Value: d(Cells(3 + a, 3 + b).Value) = Cells(3 + a, 3 + b).Value
   End If
   Next b
   Next a
  If d.Count = 9 Then ‘满足条件输出答案
  Cells(x, y) = 45 – d(1) – d(2) – d(3) – d(4) – d(5) – d(6) – d(7) – d(8) – d(9): d.RemoveAll
  Else

  d.RemoveAll
  End If
1
 Next y
Next x
