The three cups
Cup 1: Flash Grid
Flash Grid, Hard: holding a scattered pattern for a second. The first pattern has 7 tiles on a 4 × 4 grid and stays lit for 1 s.
Tip: When the grid grows, split it in your head into halves and remember which half held more light.
Cup 2: Quick Sums
Quick Sums, Mixed: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 12 − 5.
Tip: For subtraction, count up from the smaller number instead of down from the larger one.
Cup 3: Number Span
Number Span, In order · Medium: carrying a number while it grows. The first number has 4 digits, each shown for 0.65 s.
Tip: Chunk the digits as they arrive: 4-7-2 becomes forty-seven, two. Two chunks are easier to carry than five singles.
