Normal sudoku rules apply.
This puzzle is solved multiple times, each of which is called a "generation". Each generation has different rules. When solving a generation, place the generation number into the square in r1c1.
The first generation involves standard quadruples. A digit in a diamond must appear at least once in the four cells touching the circle. [Note: I switched from the usual circles to diamonds to make the dots more visible.]
The second generation uses all digits from the first generation in cells marked with a blue dot in the top left corner. In this generation, cells that touch diagonally cannot contain the same digit. (Anti-king)
The third generation uses all digits from the second generation in cells marked with a green dot in the top right corner. In this generation, cells which are a chess Knight's move apart cannot contain the same digit. (Anti-knight)
The fourth generation uses all digits from the third generation in cells marked with a purple dot in the middle. In this generation, orthogonally adjacent cells cannot contain consecutive digits. (Nonconsecutive)
The fifth generation uses all digits from the fourth generation in cells marked with an orange dot in the lower left. In this generation, for orthogonally adjacent cells, neither digit can be exactly twice the other. (Anti-ratio)
The sixth generation uses all digits from the fifth generation in cells marked with a red dot in the lower right. In this generation, cells in the same relative position in their box cannot contain the same digit (Disjoint Groups), and the negative diagonal [from r1c1 to r9c9] cannot contain repeated digits (Single Diagonal -).
Answer check will only trigger when the sixth generation has been solved.
Solve online:
- Penpa+
- CtC app
- If the dots are too hard to see, try this link for Sudokupad which uses colors instead. You can check "hide colors" in the settings menu while solving a generation, then uncheck it to transfer digits to the next generation. I tried to match the shading colors to the dot colors in the rules, but just to make sure, of the two bluish-purple colors, the lighter one is "blue" and the darker one is "purple".
Lösungscode: Row 5 followed by row 8 of generation 6 (18 digits, no spaces).

I've come away from this solve with three facts.
1) The fact that every individual generation is an enjoyable variant Sudoku on their own is impressive.
2) The fact that all six puzzles have been layered together to form this masterpiece is mind-boggling.
3) The fact that (at time of commenting) it hasn't been featured on CtC is a crime.

I'm proud of myself for having completed this. The fact this exists is incredible. The fact that you found it is mind-blowing. I had fun throughout (although a bit less with the non-consecutive generation :p). Thank you!

The link in Sudokupad has the wrong numbers in the diamond in box 6.
