No toggles this time. You see a function — you pick which of three graphs is its derivative (its slope at every point). Four rounds, instant feedback, then a score. Each playthrough shuffles the functions and their order, so hit Play Again for a fresh set.

The trap: two of the three options are the function itself and its integral. They're there because mixing up derivative, function, and integral is the single most common beginner slip. Get used to telling them apart by their slope and you've basically got calculus intuition.
