I've played many games of Balloon Sweeper over the last few days to confirm this isn't user error. I've encountered multiple situations where a safe balloon lists an incorrect number of neighboring bombs (for example, it's labeled 1, I identify the only cell where the bomb in question could be based on context from other balloons, then I click on what should be a safe neighboring balloon only to find a second bomb.) This seems to happen most frequently on diagonals, but this could be anecdotal.

My best guesses are 1) there is an error in the code that determines what number to label the balloons, 2) the code is blind to certain bombs.

I am on a laptop running the most current version of windows.
