本人喜歡玩sudoku, 但只是beginer

希望有玩家可以指點如何拆解以下啲:

5	2	3	6	4	9	1	7	8
8	4	1	2	5	7	9	3	6
6	9	7	1	8	3	2	4	5
7	6	245	459	29	8	3	1	24
2 4	8	9	7	3	1	5	6	24
3	1	245	45	6	24	8	9	7
2 4	7	8	3	1	24	6	5	9
9	3	6	8	7	5	4	2	1
1	5	24	49	29	6	7	8	3

必需每一步都加上解釋

先到先得

感謝

If set (1,5)=2 then
(1)
(1,7)=4 => (3,9)=2
(2)
(9,5)=4 => (9,4)=2 =>(5,4)=9 => (5,9)=2
(3,9)=(5,9)=2, so (1,5) =/= 2
So set (1,5)=4 then you can get the answeras below:

5	2	3	6	4	9	1	7	8
8	4	1	2	5	7	9	3	6
6	9	7	1	8	3	2	4	5
7	6	245	459	29	8	3	1	24
24	8	9	7	3	1	5	6	24
3	1	245	45	6	24	8	9	7
24	7	8	3	1	24	6	5	9
9	3	6	8	7	5	4	2	1
1	5	24	49	29	6	7	8	3

is this the only way to sort it out
i mean "to make an assumption on one of the empty spot to move on" is the only way?
any other way?  thanks.
