The three cups
Cup 1: Number Span
Number Span, Backwards · Hard: carrying a number while it grows. The first number has 5 digits, each shown for 0.52 s; type it backwards.
Tip: Chunk the digits as they arrive: 4-7-2 becomes forty-seven, two. Two chunks are easier to carry than five singles.
Cup 2: Ink & Word
Ink & Word, Medium: keeping your eye on the ink while the word pulls the other way. Forty-five seconds with 6 colours; the first card is the word ‘purple’ in blue ink.
Tip: A wrong tap costs a full second, so a calm correct tap beats a quick wrong one.
Cup 3: Quick Sums
Quick Sums, Percentages: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 10% of 90.
Tip: Percentages are friendlier as fractions: 25% is a quarter, 75% is three quarters, 20% is a fifth.
