Watch a short animation that shows you the idea, then pick the answer. Get it right and the questions get harder — and your score climbs faster. Miss one and it eases back so you can rebuild. Fill the bar to 100 to win.
✓ 50 questions across 5 difficulty levels — the app picks what's next based on how you're doing.
✓ Correct answer → points go up and the next question gets harder.
✓ Wrong answer → no points, but the next question gets a bit easier so you can find your footing.
✓ Reach 100 points and the workbook ends in a win. Otherwise, it ends the moment your timer runs out.
