A Quite Astonishing Fog-Of-War Sudoku

** TODAY'S PUZZLE ** Some of you have recommended tonight's sudoku using words like "masterpiece"... it's called Consecutive Regional Constraints and it's by Belamis. It features a twist on one of Simon's favourite rules (where you cannot repeat a digit on a constraint) and this leads to some crazy logic. Read the rules carefully, don't guess and let us know how you get on!! Play the puzzle at the links below: https://sudokupad.app/zt3l4bqwuj Rules: Normal sudoku rules apply. The grid is partially covered in fog. Correctly placed digits may remove fog from other cells. Any constraint type can not have a repeated digit. (E.g. if a 2 appears on a parity line, another 2 may not appear on any parity line.) In addition, digits across a constraint type must make up a consecutive set of digits. (E.g. if a 2 and 4 exist on dutch whisper line(s), there must also be a 3 somewhere on a dutch whisper line.) Constraint types: 1. Arrow - Digits along an arrow sum to the digit in the connected circle. Each circle is associated with exactly one arrow; 2. Region Sum (RS) - The 3x3 box borders divide a blue line into segments; each segment along an individual line must have the same sum. Each line crosses at least 1 box border and does not branch; 3. Renban (R) - Purple lines contain a non-repeating set of consecutive digits in any order; 4. Dutch Whispers (DW) - Adjacent digits along an orange line have a difference of at least 4; 5. Entropic (E) - Any three adjacent digits along a peach line are from one each of low(1,2,3), medium(4,5,6), and high(7,8,9) digits. Entropic lines must be at least 3 cells long; 6. Kropki - Digits in cells separated by a white dot are consecutive; 7. Parity (P) - Along a red line, adjacent digits must alternate between odd and even. ▶ BRAND NEW COMPETITION ON PATREON ◀ Our new competition launched today on Patreon!
