What I find strange is that it seems those clicks can also explode mines. I was given 15 minutes to solve this in a coding challenge, and still can't figure out for the life of me how someone would have approached this. It is therefore quite easy to move the board into an invalid state or to make invalid moves. For each cell in the grid, we have to check all adjacent neighbours whether there is a mine present or not. So, your class declaration should just be. In a flagging move, three values are sent in by the gamer. This is done by: These values are to be hidden from the player, therefore they are stored in numbers variable. You might also get some constant-factor time wins by iterating over the lists with enumerate instead of doing the for index in range() thing, and minimizing the number of extra variables you allocate. There must be something in that :). Additionally, you don't need to generate this list yourself, you can use random.sample: You're using this method in several places inside loops.

This is especially true for environments that allow for reordering or refactoring of methods. On subsequent games, I failed again because of this input-handling problem. When needing user input, ensure it's specific, that it's limited, and that you give responses to assist the user to provide the correct input, or allow them to exit the stage where they are.This will enable avoiding runtime errors which crash the program (such as IndexError list assignment index out of range which I encountered) and avoid having try/except/finally statements due to limiting possible inputs. no, since [-1] is a valid index (counting from the right) ;-).
