use your mouse to hover over the blocks. if they are touching your cursor then they will disappear. if its a blue one +1 time. if red one -5 time so avoid reds but get blue's!! if the difficulty icons are not appearing just click the flag again. when your time get to 0 then its game over. please put your score in comments. the default difficulty is easy.
