In this unique game, you control a sperm cell on a long journey to the egg. The goal is to cover a distance 3000 times its body length and become the sole survivor among 30 million competitors. The game is based on real biological processes where sperm compete for fertilization.

Controls are simple: use touch and drag to guide the sperm. Each region of the body presents diverse strategic situations requiring tactical thinking. Developers paid special attention to balance and difficulty levels, making the game addictive and engaging.

During gameplay, you collect broccoli to upgrade the sperm. You also need to eliminate estrogen, a female hormone that hinders progress. This adds fun and challenge.

The gameplay reflects the aggressive nature of sperm: studies show that when sperm from different males mix, over 50% attack and kill each other within 15 minutes. Some create net-like structures to block rivals, or pierce their bodies with acrosomal enzymes. Who will be the bravest and survive?
