Why It Matters

Teens spend hours online every day, and scammers know it. One bad click can leak your passwords, your photos or your location.

Every tower, defender and guardian in this game is a real habit you can use today. Defend the game, then defend yourself!

🎯 Real-Life Missions

Do these in real life, then check them off for stars in the Coder Locker.
