Review your mistakes
Every question you answer wrong is remembered. This replays them — drawn from whichever games you missed them in — until you get each one right twice.

Why review beats replaying
Playing another random round mostly re-tests what you already know. The questions you got wrong are the only ones carrying new information, and they are exactly the ones a random round is least likely to show you again soon.
This page fixes that. Every wrong answer across all fifteen games is remembered by what it asked — the country, the landmark, the sea — and replayed here. Getting one right does not remove it immediately: you have to answer it correctly twice, because getting something right straight after being shown the answer proves very little.
Missing an item again resets its progress. That is deliberate: a fact you get wrong after previously getting it right is the most valuable one in the list.
Where the questions come from
Reviews are rebuilt from the original game, not stored as snapshots, so a flag you missed on Expert can reappear with different wrong answers beside it. The point is to re-test the fact rather than to reproduce the round it came from.
