Next logical step: Naked Pair removes 8 and 9
Look at the lower-right box area first, especially r4c9 and r6c7.
How to read this visual
Look at the lower-right box area first, especially r4c9 and r6c7.
- 1 Find the pattern The two blue cells r4c9 and r6c7 both contain only {8,9}. Those two cells must take 8 and 9 in some order.
- 2 Use the restriction Because the pair uses both 8 and 9 inside the same 3×3 box, no other cell in that box can keep 8 or 9. Cross out 8 and 9 from r4c7.
- 3 Keep practicing When a puzzle feels stuck, scan each box for two cells with the exact same two candidates. That pair reserves both digits and often creates the next elimination.
Result: Remove 8 and 9 from r4c7.

Reddit reply draft for human review
Use only after checking subreddit rules and confirming the visual explanation matches the posted screenshot. The reply includes a useful answer before the link and discloses affiliation.
Look at the lower-right box. r4c9 and r6c7 are both {8,9}, so they form a naked pair. That means 8 and 9 can be removed from the other cells in that box, including r4c7.
