PLAY · LEARN ONE IDEA · PROVE IT

How LLMs train, five minutes at a time.

Each episode starts with something to play with. Then one short idea, two quick checks, and your stars.

Arcade XP measures practice with small, exact examples. It is not a module pass: practical gates still need labs, evidence, and review. Calculations you answer here also join the workbench's review schedule. Progress stays in this browser; the workbench's Export progress button includes it.
