[00:00:10]This is my walk-through and you can play this Sudoku from the link in the description.

[00:00:16]Okay, let's get it going. First thing's first.

[00:00:20]Okay, we place nine in box six.

[00:00:27]I can place also eight in box six here.

[00:00:36]And uh Ooh, uh what else?

[00:00:50]Oh, uh eight eight gives me eight here.

[00:00:56]Now, row six is missing four and the seven.

[00:01:00]Here's four.

[00:01:02]So, this will be seven and this will be four.

[00:01:11]And now I can place three in box six.

[00:01:26]And this six blocks these, this six blocks here gives me six on row five.

[00:01:33]And this will be one and the seven.

[00:01:36]Seven gives me one and the seven.

[00:01:40]One and one gives me one here.

[00:01:46]Uh these are two, four, five.

[00:01:49]Here's two and the five, so this will be four.

[00:01:54]And the last number of row five is seven.

[00:02:02]Okay.

[00:02:12]1 2 3 5 8 Um Oh, right. Um there's a double in box nine. It's 4 5 double because here's four and the five which block these cells.

[00:02:37]And this cell is blocked by four here and the five here.

[00:02:41]So, these cells in box nine cannot use four and the five.

[00:02:46]So, they will have to share these two cells.

[00:02:49]And that means these two will be three and the six. And here's six, so this would be three and this would be six.

[00:03:02]2 3 5 8 Oh, one two five Um Right, and now Um row three is missing 1 2 5 7 9.

[00:03:31]I'm going to put all of them here because this cell is blocked by 1 2 5 7.

[00:03:39]So, this is a naked single. It's blocked by all the numbers except for nine.

[00:03:46]And the nine nine nine gives me nine here.

[00:03:56]And the three and the three gives me three here.

[00:04:03]Now, that gives me because uh column one has 1 3 6 and column three now has 1 3 6.

[00:04:13]For box seven, that means I cannot use 1 3 6 in these cells.

[00:04:18]So, these will be 1 3 6 triple.

[00:04:25]I should clean this up. Three here blocks this cell.

[00:04:31]Okay, that's it.

[00:04:37]Okay, um back to row two. Um these will be 2 5 8 and this cell is blocked by two and a five, so this will be eight.

[00:04:48]And here's two, so this will be five and here's two.

[00:04:54]And these will be one and the five.

[00:04:57]Here's five, so this will be one. This will be five and here's one.

[00:05:05]Now, uh that gives me a double on row eight. It's going to be 2 7 double because this cell will be used by three or six and here's two and the seven which block these cells.

[00:05:22]So, uh two and the seven have to share these two cells on row eight.

[00:05:31]And uh that means these will be 3 4 6 9.

[00:05:38]And here's nine, here's nine and here's nine. So, these three cells cannot use nine.

[00:05:47]Mhm?

[00:05:50]>> Right. And that leaves this cell 4 9.

[00:06:02]Okay, 1 2 4 5 3 4 6 and the 2 5 2 7 8 Oh.

[00:06:22]2 4 7 8 9 Uh I'm missing something.

[00:06:31]2 6 7 Mhm.

[00:06:51]Oh, okay. I can place 9 in box 7. 9s These 9s block these cells gives me 9 here.

[00:07:13]Right. And now Okay, 4 and the 4 block these cells and this will be used by 2 or 7, so I can place 4 here.

[00:07:31]That gives me 5 and the 4.

[00:07:36]And that gives me Oh.

[00:07:38]That gives me 5 in box 8.

[00:07:46]>> And this will be 1 2 4.

[00:07:51]This is blocked by 2 and the 4 gives me 1 here.

[00:07:57]Here's 4, so this will be 2. Here's 4. 2 blocks these gives me 2 here.

[00:08:04]Now this will be 5 and the 7.

[00:08:07]7 here gives me 5 and 7 2 and the 5. 2 7.

[00:08:15]The last number or row 3 is 1.

[00:08:19]This will be 3 and the 7. 7 here gives me 3 and the 7.
