The Daily Inning
The undercard
The short version
InBallpark is a small stable of free daily estimation games. There is nothing to study for them. You need a gut feeling, a moment of thought, and the nerve to write a number down and stand by it.
Take the visual rounds in the Daily Inning, or sit with a single hard number in the Daily Question. Every answer is generated from the day's seed, so it is exact, identical for every player, and impossible to look up.
From the scorecard
Five skills, one set. In longer sets the lineup keeps rotating, with a Closer every fifth round, and the wager rides on every call you make.
Today's Size It pairing, drawn from the live seed.
How a set plays
Each round shows something real to judge: dots, objects, a filled bar, a line, a block of weight.
Resize, slide or type your estimate until it looks true. No knowledge needed, just an eye.
Stake 10, 25 or 50 points on your own closeness. Dead Center doubles it. A Whiff loses it.
Lock in and watch the true answer land. Earn up to 100 base points a round for a close call.
