I came to MathGuy_12 with this concept and he really helped kick it into full gear. Was a blast setting with him. Thanks to Calvinball, aqjhs, and sanabas for testing. We hope you enjoy!
Rules
Schrödinger Sudoku Place one or two of the digits from 0-9 in every cell of the 9x9 grid such that every row, column, and 3x3 box have all 10 digits exactly once each. For the solution checker, only enter digits in cells with one digit. Full Quad-Rank All the 2x2 areas of the grid, when read in English reading order, make a total of 64 numbers of 3 or more digits. Numbers may have leading 0s. For any 2x2 containing a cell with more than 1 digit, the extra digit in that cell increases the length of its number by one. The digits in those are always read smallest to largest. For example, a 2x2 with cells [5][7][8 and 0][3] would read as 57083 for the value of the rank. For tied ranks, a number is at rank N when N-1 numbers are of strictly lower rank (e.g. If there are three numbers with rank 20, then there are 19 numbers of lower rank and the next rank will be 23, i.e. ⋯, 19, 20, 20, 20, 23, ⋯) Clue Duality Clues in the grid are both quad rank clues AND anti-quads. Quad Rank: Clues in the center of a 2x2 area show its rank among those 64 numbers, where the lowest is 1 and the highest is 64. Anti-Quad: Digits appearing in a quad do not appear in the 4 cells touched by the quad.
Solution code: The number in rank 59 (4 to 6 digits)
