I may have found a little bug. Sometimes when you win the last mines don't get a flag: https://imgur.com/a/xLcNZ0X. My last move was to right-click on the 2 in the bottom left.

Also, right clicking on borders sometimes pops up a context menu.

That's no bug, flags are strictly placed by the player.

One of the fun side games I've been playing is to try to beat the game with the fewest possible events, which means not flagging squares - it's definitely much harder!
