Patterns are everywhere. In music, in nature, in code. Loop will teach you how to see them, name them, and make computers repeat them for you.

Before you write a single line of code, you need to see what a loop actually is. It's already all around you — you just haven't noticed yet.
"I'm Loop. I notice things most people miss. The way music has a beat that repeats. The way seasons cycle. The way your morning routine is the same every single day. That's all loops."
A loop is anything that repeats. In code, instead of writing the same instruction 100 times, you write it once and tell the computer how many times to repeat it.
Think about brushing your teeth — you do the same back-and-forth motion over and over until you're done. You don't think through each stroke. Your brain runs a loop. Computers do the exact same thing, just way faster.

Look at the pattern and tap the right shape to fill the blank. Loop says: find the rule first, then fill it in.
Pattern 1 — Every other one
Pattern 2 — Two then one
This is what a loop looks like running in real time. Each step lights up as it executes. Change the speed and watch what happens.
Name one thing in your day that repeats — something you do the same way every time. How many times do you think you've done it in your life so far?
Loop has pattern challenges, a live loop builder, nested loop puzzles, and a final challenge that'll rewire how you see repetition forever.
