Normal Sudoku Rules apply. SANDWICH CLUES- Numbers outside the grid are the sum of all numbers BETWEEN the 1 and 9 within that row or column. EACH RULE BELOW HAS FIVE EXAMPLES IN THE PUZZLE. TWO EXAMPLES OF EACH RULE DO NOT CORRECTLY FOLLOW THE RULE. IF A CELL IS ON A CORRECT EXAMPLE OF A RULE IT IS CORRECT FOR ALL OTHER EXAMPLES THAT INVOLVE THAT CELL. GRAY LINES- Numbers on gray lines sum to the number in the attached circle. Numbers may repeat on gray lines. CONSECUTIVE PAIRS- Numbers with a white dot between them are consecutive. Not all possible dots are shown. DUTCH WHISPERS- Numbers on red lines are at least 4 apart from their neighbors on the line. Numbers may repeat on red lines, if other rules allow. ANY neighbors not 4 or more apart make the line incorrect. XV PAIRS- Numbers with an X between them sum to 10.

@Will Power: I began working on this puzzle when you posted the link on your Prime Arrows puzzle. It wasn't until I read your reply to VitP that I realized an incorrect assumption that was crippling my solve. After that, home free.

Changed rules text from "rules" to "examples of rules" in certain areas to clarify meaning. Thanks to VitP for noting possible confusion. -Will Power

i think there's a problem with the rules.

first of all, "IF A CELL IS ON A CORRECT RULE IT IS CORRECT FOR THE OTHER RULES ALSO." doesn't mean anything, because there are NO single-cell clues, and another rule states that if a rule is even SLIGHTLY wrong, it is considered to be wrong.

second, i think you have to use the idea that the overlap of the 4 long lines means they are ALL correct or ALL wrong, otherwise there's no way to solve this puzzle.

@VitP Thank you for your comments. The SANDWICH CLUES rule is first, and does not fall into the "each rule below" section. This is strengthened and clarified by the fact that there are only three sandwich clues, where the section below specifically mentions there are 5 examples of each rule that need to have 2 incorrect examples (also called liars in other puzzles from other people). Knowing that the rules after the sandwich rule don't apply to the sandwich rule, I have just re-colored all cells on incorrect rule red and all cells on correct rules green, with no overlap of colors. Your second observation seems logical to me. Please use that observation if it advances your solve. I stand by the rules as they appear in the puzzle. However, there may be some confusion that i cannot anticipate if you are depending upon a translation into a different language that i cannot control. Peace to you. -Will Power

All, This is the first puzzle I had requested testers to review before I released. The only feedback I got was favorable, so I hope you like it. (See comments from RailMan on my puzzle "Prime Arrows", if you completed that one). It's probably 2.5 stars on LMD, but RailMan suggested 3. Peace to all. -Will Power
