A different test each round, picked at random. You’ll see each one as it comes up.

10–20 seconds to answer each round
The clock starts once you can answer. At zero, whatever you’ve set is locked in.
Closer scores more
Up to 100 a round, scored by how far off you are, not right or wrong.
Watch closely
Some rounds show something only once.
