Howbigle

Howbigle is a daily size estimation game from an independent developer who does not give a name, launched with puzzle #1 on 12 November 2026. Every round puts a dark silhouette of an adult human, 5 ft 7 in (1.7 m) tall, next to an orange silhouette of the day's object. The object starts at the same size as the person. You drag the slider, swipe or pinch the picture, or tap the minus and plus buttons until the object looks the right size, then lock in.

The first board asked for the length of an Olympic swimming pool. The rest of that day's five were a Boeing 737-800, the Empire State Building, a saltwater crocodile and a green anaconda. After each lock-in the reveal shows your guess and the true size side by side, how many times too big or small you were, a comparison in adult humans, and a short note with a source link for the measurement.

Scoring works on ratios. A guess within 6% of the published size earns 100, and the score then falls off smoothly, so guessing double and guessing half cost the same. A guess twice the true size scores 36, and one five times off scores about 8. The five rounds add up to a total out of 500, and the share text gives the puzzle number, your total and five coloured squares without giving the answers away.

The daily set changes at midnight Eastern time and is the same for every player. Scores and your streak are kept in the browser, with no account. A separate Unlimited mode serves practice objects from the same bank at any time and leaves the daily score alone. The site lists a Fermi style number mode and archive tools as planned for later.

The game suits anyone who likes the size comparison idea and wants a short, quiet daily with no timer. Its objects mix animals, buildings, vehicles and natural features, so a feel for feet and metres helps more than trivia knowledge.
