Digit Recognition Test

What to expect

• A digit string shown for 10 seconds to memorise, then hidden — one viewing only.
• A multiple-choice question (four options): how many times a given digit appeared. You have 10 seconds.
• 5 rounds that grow from 6 digits, +2 each round.
• After each answer the string is shown again (with that digit highlighted) so you can verify the count.

What it measures

• Short-term memory for numbers
• Holding a sequence after it disappears
• Concentration as the strings get longer

Instructions

1. 1Memorise the digit string during its 10 seconds on screen.
2. 2When it disappears, answer 'how many Ns were there?' within 10 seconds — pick from the four options.
3. 3Check the reveal that follows to see how many times the digit really appeared, then continue.
4. 4One viewing per string; you can't change an answer once picked.

Tips

• Keep a running tally of the digits that repeat rather than memorising the whole string.
• When a string gets long, focus on the digit types most likely to be asked about.
• Chunk the digits into groups of 3–4 as you read them.
• Stay relaxed — tension shrinks your effective span.
