If I'm interpreting the last line correctly, then I would propose rewording the rules to avoid confusion:
- Cells separated by an X must sum to 10. All possible Xs are given.
- Grey lines are palindromes and must read the same in each direction.
- The cells that are on palindromes include exactly four hidden "X Cells". Digits on either side of these cells must sum to 10.

Very nice puzzle. This would have been a great addition to that CTC puzzle hunt themed on negative constraints. Thanks!

Love it. A funny concept executed well, and I love the way the solve just suddenly snaps into focus.

Very cool concept! Reminds me a bit of the fog of war April Fools puzzle that was on CtC. I really enjoyed the logic of identifying and locating X :)
