How good is your eye?

Freehand is six free daily estimation games

Every game here asks you to judge something by eye that you would normally measure: an angle, a weight, a landing, a balance point, a count, a length of time. No instruments, no formulas, no sign-up. Each game gives you five rounds a day and one attempt at each, the same five puzzles for everyone everywhere, then shows you where your score sits on the day’s curve. A guessing game, in other words, where the guess is the whole skill.

• Angled: angle estimation gamePlay Angled, a free daily angle guessing game. See an angle for three seconds, then rebuild it from memory. Five rounds, no protractor, no sign-up.
• Halved: cutting gameSlice a lopsided 3D object so both halves weigh the same, by eye alone. Five objects a day, one cut each, scored on how close you came.
• Dropped: landing guessing gameWatch the start of an arc, then call where the ball lands before it gets there. Five throws a day, one call each, no formulas.
• Balanced: balance gamePick the one point an irregular shape will sit level on. Five shapes a day, one attempt each, scored on how far it tips.
• Counted: counting gameA shelf, a tray, a table, a bunch, a crowd, shown for a moment, then gone. Say how many. Five scenes a day, one guess each.
• Timed: time estimation gameHold the button for an interval and let go when it's up. There is no clock. Five intervals a day, one attempt each.

New puzzles arrive at midnight, local time. Nothing to install: Freehand runs in the browser on a phone or a laptop. Your progress is saved on your device, and completed daily scores are submitted to the shared board under an automatically assigned name. You can change that name without creating an account.
