Try a tiny Blocks Studio right here
This teaching version is intentionally smaller than the full editor, but it really runs the blocks you arrange. Drag, reorder, edit values, press Green Flag and watch the Stage change.
A five-minute challenge
Make the cat move, speak and turn. You can drag blocks from the palette or click them to append them.
Open Events and add “when green flag clicked” if it is missing.
Open Motion and add “move steps”.
Open Looks and add “say text”.
Press Green Flag.
Change the numbers/text and run it again.
What this demo really does
The demo maintains an actual block stack in React state, accepts HTML drag/drop, reorders blocks, edits block inputs, executes the sequence asynchronously, updates sprite position/rotation/message, and synthesizes UI/game tones with Web Audio.
It is smaller than RC Blocks Studio on purpose: it teaches the interaction without loading the full 2,385-block catalog into a docs page.
Next step
After the mini studio makes sense, open the real RC Studio, switch to Blocks, and recreate the same three-block behavior there.
