What Amountle is
Amountle is a free daily visual estimation game. Objects pour into a clear container. You watch the drop, then type how many you think made it in. There are five rounds, the same piles for everyone that day, and a score out of 500 when you finish.
It used to be called Ballpark. The loop is the jelly-bean-jar problem with a timer and a leaderboard: you are judging volume and flow, not inventorying every sphere. A full daily takes about two minutes.
Rules and scoring
Each daily puzzle is five independent piles. For every pile you get one number. Closer guesses score more. An exact hit is 100 points for that round, so a perfect day is 500.
You have a short window to commit after the drop — the about page clocks it at fifteen seconds per round. When time is up, or when you submit, the true count is revealed immediately. You can rotate the settled pile before answering so you are not stuck with one camera angle.
The point is quantity, not a census. If you try to count every object in a fast pour, the timer will beat you. Leaderboard names you see on the home screen (scores in the 400s are common) are people who stayed close across all five rounds, not people who nailed every total.
Practice modes do not overwrite the daily result. Extra modes on the same site:
- Over / Under — a line is set; you only say above or below.
- Fill — the inverse of the daily. A target count is shown and you tap to drop one object or hold to pour, trying to match that number before the timer locks your pile.
- Survival — keep estimating until you miss the allowed window.
How to play the daily
- Open amountle.dev and start today's puzzle. A container sits on a dark stage. Shapes begin falling in — spheres most days, sometimes other solids such as tetrahedra.
- Watch the whole pour. Track clumps, bounce-outs, and how fast the stream is, then spin the settled pile if the front face is hiding a gap.
- Type one integer before the timer ends. There is no second guess. Submit, or let the clock lock it.
- Read the true count and your points for that round. Four more piles follow, often with a different density or shape so you cannot reuse the last number blindly.
- After round five you get a total out of 500, a round breakdown, and a place on that day's leaderboard. Share or duel a friend on the same seed if you want a head-to-head.
A typical miss looks like this: the jar looks "about two-thirds full of small balls," you punch in 80, the reveal is 94, and you lose a slice of the 100 instead of the whole round. Being off by ten on a busy pile still scores. Being off by ten on a sparse pile does not.
Tips
- Estimate in bands first (40s, 70s, 120s), then nudge. Changing 80 to 86 is cheaper than rebuilding the number from scratch with two seconds left.
- Fast pours hide more than slow ones. If objects stream in a blur, bias slightly higher than the tidy pile your eye wants to report.
- After a reveal, note the leftover air in the jar. That leftover-space memory is more useful on the next round than copying the last answer.
- Fill mode is the best practice for the daily because it trains the same volume-to-count mapping in reverse: you feel what 40 versus 70 actually looks like in that container.
- Survival and Over / Under are useful when you have already burned today's five and still want to keep your eye calibrated.
