In this game rows of various colors descend from the top of the screen and you have to and you have to shoot your own supply of eggs at them through your tool. If three or more eggs of same colours match, they explode. Be sure, if the mass of the egg descend to the bottom of the floor, the entire screen will be crushed by the foot of Mama Brontosaurus and the game will come to an end. Use your mouse to aim at the egg and left click to fire. Break several clusters of eggs in a row to earn combos and bonus points. When you break a cluster, those eggs that are left unsupported underneath (hanging eggs) also break, adding valuable points to your score. There are various bonus points available in the game. Complete the puzzle in less than 200 moves and get a bonus added to your final score. One interesting aspect to make the game increasingly difficult as you play a single game for a longer amount of time is the inclusion of Whirley. Every minute or so during gameplay, a dinosaur will announce "Whirley's coming!", and soon after, Whirley will fly across the screen carrying an egg of a color not yet on your screen. If Whirley is allowed to fly across the screen untouched, the color of his egg will be added to the pallet of colors in the egg mass, and the rate of the eggs' descent will reset to the default slow speed.
