The three cups
Cup 1: Light Trail
Light Trail, Hard: keeping an order of shapes and notes. The first trail is 4 steps long on 9 panels; each panel glows for 0.36 s.
Tip: Listen as well as look. Each panel always plays the same note, so a trail is also a little tune.
Cup 2: Quick Sums
Quick Sums, Division: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 36 ÷ 4.
Tip: Round and adjust: 38 + 47 is 40 + 47 minus two.
Cup 3: Number Span
Number Span, Backwards · Easy: carrying a number while it grows. The first number has 3 digits, each shown for 0.8 s; type it backwards.
Tip: Type steadily; there is no clock while you answer.
