📜 Game Rules – SudokuIQ (Modulo-9 Variant)
🎯 Goal of the Game
Fill the 9×9 grid with symbols so that, once decoded, it forms a valid Sudoku: each digit from 1 to 9 must appear exactly once in every row, column, and 3×3 square.
🔢 Symbols Instead of Digits
Instead of digits 1–9, you use symbols:
Each symbol hides a Sudoku digit.
🧩 How the Symbols Work
The value of a symbol depends on the 3×3 square it is placed in.
The same digit looks different in different squares, but changes follow simple shifting rules.
🔄 Symbol Shifting Rules Between Squares
Horizontally:
Moving right → add +1 to the symbol
Moving left → subtract –1
Vertically:
Moving down → add +3
Moving up → subtract –3
⚡ If the value goes beyond the range (e.g. 111 → +1), it wraps around and becomes BIN.
🔢 Square Numbers
Each 3×3 square has its own number (1–9). Symbols shift depending on the square they are in:
horizontally by +1 / –1
vertically by +3 / –3
📌 Examples
If the digit 5 in classic Sudoku corresponds to 100 in the first square (top-left):
In the second square (to the right) it will be
101.In the third square (further right) it will be
110.
If the same digit 5 in the first square is 100:
In the fourth square (directly below) it will be
111.In the seventh square (further below) it will be
001.
🕹️ How to Play
Click an empty cell and choose a symbol from the panel.
Follow Sudoku rules – check entire rows, columns, and 3×3 squares.
Use the shifting rules to track the same digits across different squares.
🏆 Victory
The puzzle is solved when all cells are filled with symbols that, once decoded, form a valid Sudoku grid.
