Logic Masters Deutschland e.V.

A recent puzzle inpired a thought: what if I just took one of each constraint and laid them down a diagonal? That was the genesis for this puzzle. The first version of this puzzle (without the 2 and 12 Sandwich clues), while solveable, was not enjoyable. It was a ridiculously easy start followed by a brick wall, then a mediocre finish. I called that one Smorgasboard Roller Coaster. I decided to make it more consistent and added the two additional Sandwich clues, leaving it an easy solve throughout (and maybe a good primer for folks to learn Disjoint Groups). If you really want a challenge, you can always ignore the 2 and 12 Sandwich clues ;-)

Normal Sudoku rules apply.

Arrows: Digits along the arrow must sum to the given total in the circle (r5c5, r4c4,r5c3 and r5c5, r4c4,r3c5)

Between Lines: Digits along the line between the circles must come between the circles values (r4c4-r9c9)

Disjoint Groups: No number can repeat in the same position in 3x3 boxes.

German Whisper: Consecutive digits along the Green lines must differ by at least 5 (r8c8 - r9c9)

Killer Cage: Cells sum to the number given in the upper left corner of the cage (dotted lines)

Kropki Dots: Digits separated by black dots must be in a ratio of 1:2. Digits separated by white dots must differ by 1

Maximum: Gray cells with outward arrows indicate that cell is greater in value than all of its surrounding cells. Note: This clue is hidden by a Between Line circle, in r9c9

Minimum: Gray cells with inward arrows indicate that cell is lesser in value than all of its orthogonally surrounding cells

Negative Diagonal: Numbers do not repeat along the r1c1-r9c9 diagonal

Quadruple: Numbers in the small circle must appear within the surrounding cells

Renban: Purple lines contain a consecutive set of non-repeating digits, in any order (r6c6-r8c8)

Sandwich: Numbers outside a row or column indicate the sum of the digits found between the 1 and 9 in that row or column

XV: Digits separated by an X must sum to 10. Digits separated by a V must sum to 5

... That's 3 in the corners ... losing their religion ;-)
