Sudoku, minesweeper and memory combined

Is it safe? Are you safe? Can anyone be safe nowadays? Are you concerned about your safety? Do you shower in life-jacket? We don't know that, but in our game you can check if small colored squares are safe. You may ask - in what sense? In philosophical sense? In political sense? In first order set theory sense? You won't learn that from us, we leave that to your imagination. No one can scare you as well as yourself!
