Getting Started with the Scratch Simulator
Last updated: August 8, 2026
What you're practicing: building your first program using blocks instead of typed code.
1. Click "Open" to launch the simulator.
2. Click a Motion block (e.g. "Move 10 steps") to add it to your script -- it appears in the middle script area.
3. Click the green Run flag and watch the cat sprite move.
4. Add a Turn block after it, run again, and see how direction changes what Move does next.
5. Add a Say block so your sprite talks.
6. Try a "Repeat 4 times" block wrapped around Move and Turn -- that's how you draw a square with almost no blocks.
7. Click the X on any block to remove it, or Reset Sprite to start the stage over.
8. When you're happy with your script, click Save This Project to keep it.
Tip: build 2-3 blocks, run, watch what happens, then add more -- that loop (build, run, watch) is exactly how real programmers work too.
