Here's my latest experiment with palindromes and kropkis. I hope you enjoy. As always, feedback is welcome and encouraged.

• Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each.
• Palindrome Lines: Digits along a gray palindrome line must read the same forwards and backwards in either direction.
• White Kropkis/Black Kropkis: Digits in cells separated by a white dot are consecutive. Digits in cells separated by a black dot have a 1:2 ratio.
