• Build a Teleporter — exact x/y positions
• Draw With Loops — repeat blocks that draw shapes
• Animate & Add Sound — say, show/hide, and sound blocks
• Wire Up Game Controls — make your world react
• Build a Scoreboard — variables that keep score
• Make Smart Decisions — if-blocks and sensing
• Build a Racing Game, a Catching Game, and an Interactive Story — put it all together
