On the Subject of Pink Sudoku

But what do the circles mean?

• 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.
