This is a “Twisted Tuesday” puzzle variation.
Theme: Doctor Sudo-Who?
Rules: Standard Sudoku rules except that instead of the numbers 1-9 this puzzle uses the letters in “WORD BATCH”.

No cell may be used more than once in a single path, but the same cell can appear in the paths of different words/phrases.
