The brief
All my exes lunch in Texas: as you can see, none of them are located outside the state! Normal sudoku rules apply. Digits along the Texas border (yellow line) alternate even/odd. Digits in cells separated by an X sum to 10. All possible Xs are shown. (Negative constraint applies). Digits along the purple (Renban) line are a set of consecutive digits, in any order. Number outside of the grid indicate the sum of the digits appearing between 1 and 9 in that column (sandwich sums).
