I made this puzzle to celebrate three years of subscribing to Olli Wright twitch channel: twitch.tv/olliwright.
It was also inspired by the wonderful All Four One puzzle by AnalyticalNinja and co.
I hope you enjoy solving it!

Rules:
QUATTROQUADRANTS:
– The grid contains four overlapping Quattroquadri (QQ) grids, outlined in a color matching the clues within it.
– Each QQ contains four 3x3 square regions that each contain the numbers 1-9, without repeating within a row or column of the 6x6 area that this QQ occupies. Digits may repeat within a full nine cell row or column of the grid so long as each QQ is valid.
Entropy Line: Each set of three consecutive digits on a Peach entropy line has to contain a low (1,2,3), a medium (4,5,6), and a high digit (7,8,9).
German whisper: Two cells connected by a Green line must have a difference of at least 5.
Renban: Digits along a Purple renban line form a sequence of consecutive digits in any order.
Thermo: Along thermometers, digits must increase from the bulb end.
Kropki: Cells separated by a white dot must contain consecutive digits. Cells separated by a black dot have a 1:2 ratio. Not all dots are necessarily given.
Lösungscode: Row 9 digits from left to right (9 digits).

Oh, clever! Pretty tricky to not forget that box 1 digits don't eliminate box 3 marks, but I got through it anyway :P
