The three cups
Cup 1: Quick Sums
Quick Sums, Division: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 40 ÷ 5.
Tip: A skipped problem costs less time than a long stare. Press OK and keep the rhythm.
Cup 2: 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 3: 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.
