Welcome.

Pick the BEST test. Beat the timer.

Only the single best test counts — overkill (e.g. Ratio on a geometric series) is wrong.
Wrong answer or timeout costs a life. 3 lives total.
After a correct test (other than Divergence/AST) you get a 10 s bonus prompt to call convergent or divergent — multiplies your points by 1.3 / 0.7 / 1.0.

Tip: number keys 1–9 map to the test buttons (reading order).
