The three cups
Cup 1: Quick Sums
Quick Sums, Division: steady mental arithmetic against a gentle clock. Sixty seconds; the first problem is 18 ÷ 2.
Tip: For subtraction, count up from the smaller number instead of down from the larger one.
Cup 2: Reaction Time
Reaction Time, Left or right: waiting calmly and moving the instant something changes. The first eight waits fall between 1.39 and 3.46 s.
Tip: Look at the panel, not at your finger. The change is easier to catch straight on.
Cup 3: Flash Grid
Flash Grid, Medium: holding a scattered pattern for a second. The first pattern has 5 tiles on a 4 × 4 grid and stays lit for 1.1 s.
Tip: If you miss twice in a row, take a sip of tea before the next round. The game waits for the countdown, not for you to rush.
