The three cups
Cup 1: Step Back
Step Back, Letter · 1 back: keeping a short list moving through your mind. 21 letters, 6 of them matches; letters used: C, F, H, K, L, N, R, T.
Tip: Start at one back until it feels dull, then move up. The jump to two back is the big one.
Cup 2: Number Span
Number Span, In order · Easy: carrying a number while it grows. The first number has 3 digits, each shown for 0.8 s.
Tip: The numbers never repeat a digit twice in a row and never run in steps like 4-5-6, so you do not need to guard against those.
Cup 3: Quick Sums
Quick Sums, Addition: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 9 + 3.
Tip: For subtraction, count up from the smaller number instead of down from the larger one.
