Can somebody explain the last condition?

How did you understand the last condition? It contradict the first condition. If the cell is not a mine and no neighbours has a mine, it should recursively call itself on each neigbhour, but the last condition says it should not call anything.

just got it a few minutes ago, corrected my code according to your remarks, still, thank you a lot But regarding the requirements, i don't understand how that was explained in the last requirement, i call another method that takes coordinates and string.

1) When you create your game, on line 38, you count the neighbors of every element by calling your method getNeighbors and store the value on countMineNeighbors. On line 90, you have the value already, but you call your function to recalculate it. 2) On line 98, 99, you are going to open a cell, which is not a mine, and display its value, but if it's a 0, it shouldn't display anything, just an empty string.
