The three cups
Cup 1: Quick Sums
Quick Sums, Mixed: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 4 × 9.
Tip: Percentages are friendlier as fractions: 25% is a quarter, 75% is three quarters, 20% is a fifth.
Cup 2: 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: For backwards, build the number in pairs from the end while it is still appearing, rather than reversing it all at the last moment.
Cup 3: 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: Say the trail quietly to yourself by shape: circle, star, drop. Words travel further than pictures for many people.
