We made Ballpark, a free daily game: five questions, each with a number for an answer (how tall, how far, how many, how heavy). Slide or type your guess. Too high and too low count the same: the exact answer scores 200, and twice off still scores 100. Each answer is checked against two independent sources, named on the day's answers page once the day is over everywhere.
Everyone gets the same five, new at midnight. No sign-up: https://witsday.com/ballpark/?ref=lemmy
