Two snapshots of BrainiLab play
Our first study began with 200 recorded games. A later snapshot contains 192 completed rounds with checked answers, drawn from 227 recorded completions. The two snapshots ask different questions and cover different dates.
Start with where BrainiLab players shone in the first 200 games, recorded from 28 August to 18 October 2026. The new readings use BrainiLab’s aggregate data for 19 October to 9 November 2026 (UTC).
Choose what to explore
- Which quiz rounds did we count? follows the exclusions from 227 to 192.
- Which games appeared in the sample? shows how completions were spread across game types.
- How did Easy and Medium scores compare? keeps the comparison within one General Knowledge quiz.
- What does a typical quiz score look like? compares the mean and the middle round.
- How many profiles played again? separates repeat rounds from the number of profiles.
Go deeper into the games and the numbers
- Math Rush: the minute is short, accuracy still matters looks at a separately dated sample from one timed game.
- Mean vs median: the biscuit tin that changes the average shows how to calculate both summaries with a simple example.
- Daily or Anytime: what would you like to play? explains the two routes into a round. Our data study does not use the two routes as comparison groups.
- How to remember what you learn in a quiz offers something to try after a round. The repeat-play figures do not measure how much anyone remembered.
Read the numbers in context
A round is one recorded finish. A profile can finish several rounds. An answer is one item inside a round. Each story says which of these it counts.
Both snapshots describe recorded activity. Players chose what to play and whether to finish. Use the two snapshots to explore what happened in each sample.
