If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Different iron man icons are falling from the top of the screen. To vaporize them, get 3 or more of the same images with iron man in a row vertically or diagonally. You must hurry and complete the game before your time runs out. Use the special blinking hexas image to eliminate more iron man icons. You can increase your time limit by clicking the time button only one time per level.
Use your mouse key to connect three or more iron man icons.
