The brief
Normal sudoku rules apply.
Pink lines contain a non-repeating set of consecutive digits in any order (Renban).
Adjacent digits along the green line must differ by at least 5 (German Whisper).
Any set of three sequential digits along the orange line must consist of a low (1-3) digit, a middly (4-6) digit, and a high (7-9) digit (Entropic).
Blues lines have an equal sum N within each box they pass through (Region Sum). N may be different on each line.
