The three cups
Cup 1: Step Back
Step Back, Letter · 3 back: keeping a short list moving through your mind. 23 letters, 6 of them matches; letters used: C, F, H, K, L, N, R, T.
Tip: In position mode, give the squares names like clock positions; names are easier to shuffle along than places.
Cup 2: Quick Sums
Quick Sums, Division: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 12 ÷ 3.
Tip: Round and adjust: 38 + 47 is 40 + 47 minus two.
Cup 3: Number Span
Number Span, In order · Hard: carrying a number while it grows. The first number has 5 digits, each shown for 0.52 s.
Tip: Type steadily; there is no clock while you answer.
