Mission of The Great Sperm Race is to be the first on the egg! Race against 250.000.000 other sperm and fertilize the egg. Control the single sperm with the arrow keys. Be fast but keep distance from the sticky walls or you will get stuck and your chance of being the most important sperm in this race is over. The sticky wall also moves and discharges parts of its masse to make your victory march even more difficult.
Don't think you can just leisurely make your way up there though, the time is running and you don't want to be overtaken by some nasty little sperm. Do you have what it takes to fertilize the egg and be the fastest of them all? Find out and have fun playing The Great Sperm Race online and for free on Silvergames.com!
