How is this scored?

Ranked by overall % accuracy across all parties — there are too many seats up for grabs to score per-seat exactness fairly.

  • For each party we work out how many seats your guess was off by
  • Add those up, divide by the total seats, and that's your error rate
  • Accuracy = 100% − error rate, capped at 0%

So nailing the big parties matters most: being 50 seats off on Labour costs more than being 50 off on Reform.
