Here is my latest puzzle. It represents some more experiments with palindrome lines. 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.
- 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.
- Palindrome Lines: Digits along a palindrome line must read the same forwards and backwards in either direction. There are four separate palindrome lines of different colors which all meet in the center square.
- X/V: Cells separated by X must sum to 10. Cells separated by V must sum to 5.

Great fun. Could have been a 2* for me, until I finally spotted the interactions.
