Twelve questions, a few seconds each. Think fast or do not think at all.
Twelve questions and a clock that drains while you read. Most of them you could answer in your sleep given a minute; the game is that you do not get a minute.
The clock is set per question rather than fixed, so a long word problem gets longer than a two-word comparison. Running out of time scores the same as getting it wrong, which is the honest way to treat it.
Being right matters more than being quick. A correct answer near the buzzer still beats a fast wrong one, comfortably.
This measures how you handle a question under a small amount of pressure, on whatever device and connection you happen to have. It is not a test of intelligence or of reaction time in any clinical sense — a phone that stutters costs you a tenth of a second and there is nothing the game can do about that. Play it for the pressure, not for the number.
