- Sudoku: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Search 8 or 9: A digit in an arrow shows the distance to a cell containing a 8 -or- 9 in the indicated direction (not necessarily the 8 or 9 closest to it), with 1 pointing to the cell directly adjacent to it. Not all arrows are necessarily given.
An example 6x6 sudoku with the same ruleset, except the digits searched for are 5+6:
You can play the main puzzle online using:
- CTC app: http://tinyurl.com/mv2fjsdf

Hope you'll enjoy!
Solution code: Row 8 and column 8. I.e. the 9 digits in row 8 from left to right, followed by the 9 digits in column 8 from top to bottom, for example: 123456789123456789

Absolutely mindblowing how all of the clues got resolved at the end, especially the one spot around those two particular columns. Thanks for this beauty ;)

Almost symmetrical, almost impossible!

Beautiful puzzle ! The arrows in R8 really gave the breakthrough. Wonderful setting. Thanks for sharing.

I opened this one up a few days ago and thought, nope! Then I saw CTC feature what I thought was this puzzle, so I attempted and solved it. So I came back here to find it, and lo and behold the CTC video was a different, prior 8-9 puzzle. That puzzle certainly prepared me for this one, and this one is certainly more challenging. Both are amazing sets, highly rewarding, and definitely fun! Thanks!!

So many arrows, so much fun! Love the idea of having to search for multiple digits :) Thanks for sharing.
