How the Scoring Works

Type an estimate and press Enter. The exact answer and how far off you were show under the box, and the next question starts straight away.

An estimate within 1% of the exact answer scores 10 points, within 5% scores 7, within 10% scores 4 and within 25% scores 1. An estimate further off scores nothing. Double the answer and half the answer count as equally far off.

There is no rating. The questions get harder during a round, so a fast player reaches the hardest questions. A quick rough estimate can score more over the round than a slow exact one.

Typing Estimates

Commas are optional. A k means thousand, an m means million and a b means billion, so 30k is 30,000.
