1 in 300 Million

You are one of 300 million sperm racing to reach the egg in this silly, biology-themed comedy game. Control your sperm by tapping to swim and steering with your finger, dodging obstacles like acid zones, immune cells, and dead ends. The game features solo races with a global leaderboard where you can watch top player replays, online multiplayer battles for up to 11 players with partner selection and special skills, and a progression system with 30+ titles to unlock. A unique feature lets you upload your own face onto your sperm avatar (stored locally, never uploaded). The game supports 9 languages and original background music, optimized for vertical mobile play.
