On the Subject of Green Sudoku

Is zero even? I can't remember.

• The palette to the right of the sudoku grid is ordered 0-9. Any numbers referenced in this manual refer to the numerical value of the corresponding colour in the palette.
• Selecting any colour from the palette then selecting any cells will apply that colour to those cells.
• Pressing the ‘reset’ button will reset the sudoku grid to its starting state.
• Upon pressing the ‘submit’ button, if the state of the grid is valid, the module will solve. If the state of the grid is not valid, a strike will be incurred.

Kropki Sudoku Rules

Fill the grid with colours such that no colour appears more than once in any row, column, or 3x3 box.
Each dot on the grid displays either an even or odd number.
All possible Kropki dots are displayed on the module
If the dot displays an even number, the two cells either side of the dot have a relationship of 2:1 (one cell has double the value of the other).
If the dot displays an odd number, the two cells either side of the dot have a difference of 1 (one cell has a value of one more than the other).
