I went to the Monthly Sudoku Contest but the puzzle is not showing inspite of clicking on the Reset button and pressing the 'Control' button while left clicking on the mouse. What should I do?
I assume you mean the Beginners' contest, since the puzzle tests don't have an interface. The puzzles will show only when you've clicked "Start Classics"/"Start Variants" button, and then you will have 40 minutes to solve and submit the answers. As of now there is no record of you starting the test.
