### I can't find more than 4 numbers on that puzzle!?

Here is a level 5 puzzle I was attempting. This is from a 'Tazuku' book that goes up to level 6.

Code: Select all
`. . . | . 7 . | . . .3 . . | 1 . 9 | . 4 5. . 4 | . . 5 | 9 7 .------+-------+------. . 9 | . . . | . . .4 8 7 | 6 . . | . . .. 5 . | . 3 . | . . 2------+-------+------. . . | 7 . . | . 6 9. . . | . . 3 | . . .. . 2 | . 8 . | . 1 .`

After much reflexion, I have only filled 4 cells!! r2c2, r4c1, r4c2, r7c3.
Code: Select all
`. . . | . 7 . | . . .3 7 . | 1 . 9 | . 4 5. . 4 | . . 5 | 9 7 .------+-------+------2 3 9 | . . . | . . .4 8 7 | 6 . . | . . .. 5 . | . 3 . | . . 2------+-------+------. . 3 | 7 . . | . 6 9. . . | . . 3 | . . .. . 2 | . 8 . | . 1 .`
If anyone can help I would be grateful. Thanks!

The puzzle isn't valid. You show 2 7's in c4/b8.
