How scoring works
- Time: pick the right window and score 10 ÷ the chance of that window. Under 3 minutes is about a 26% chance (39 points). Over 20 minutes is about 14% (74 points).
- Pool: score 10 ÷ the pool's share of the last 24 hours, up to 100. Guessing the biggest pool is safe but cheap.
- Transactions: within 5% scores 40, within 10% scores 25, within 20% scores 10.
Time is measured from when you lock in to the block's own timestamp, which miners set. It can be off by a minute or so. The score is just for fun: no money, no prizes.
