This puzzle is inspired by What Lies Beyond the Fog by ViKingPrime, which also explored the interaction of S-cells and counting circles. Thanks to the CtC fan discord for testing. Hope you enjoy!
- Schrödinger Sudoku: Place one or two of the digits 0-9 in every empty cell such that each row, column and box contains the digits 0-9 exactly once.
- Fog: The grid is covered in fog. Placing correct digit reveals clues in the surrounding 3x3 area.
- Circles: A digit in a circle counts exactly how many circles with the same letter contain that digit. Each letter A-E appears on exactly 3 (out of 15) circles.
- Values: The value of a cell is the sum of its digit(s).
- Renban: Values on a pink line form a contiguous sequence without repeats.
- Kropki: Values on a black dot are in a 1:2 ratio.

What a great puzzle! The logic behind the breakthrough for the first digit was brilliant. The logic behind all the rules and how they all come together ...just WoW! I'm usually a 3 stars guy and dabble in the 4 stars. Still can't believe I solved it lol. Hope this gets on CTC. Kudos GDC.
