How well can you trust your eyes? Gauge is a free browser estimation game: five quick rounds, the same for everyone each day. No signup, no clock-watching menus — a full daily takes about a minute.
| COUNT | A cloud of dots flashes for a moment, then vanishes. Drag left/right to set how many you think you saw, then lock it in. |
| POUR | Fill the glass to an exact percentage — but the glass has no markings. Drag up and down to pour. |
| ANGLE | Set the dial to an exact angle with no protractor. Drag around the hinge to swing the arm. 0° is the flat gray line pointing right; 180° points left — angles open counter-clockwise, so 90° is straight up. |
| HOLD | Press and hold for an exact number of seconds — with no clock. Release when your inner metronome says so. (Slipped and released instantly? Releases under a second are forgiven — just press again.) |
| LENGTH | A line is shown at an angle. Stretch your own line to match its length exactly. |
Every round scores your accuracy from 0 to 100% — the closer your estimate, the higher the score. Your daily result is the average of the five rounds, plus a five-square trail (🟩 sharp · 🟨 close · 🟥 way off) you can copy and send as a challenge — the link carries your score, so a friend who opens it is dared to out-eye you. Come back tomorrow for a fresh gauntlet and build a daily streak — beat yesterday's score to sharpen it, and if you miss a day your personal best is saved and waiting to be beaten. The menu shows your last seven days as a chain of squares — each finished gauntlet fills one, and today's pulses until you play. Don't break the chain. After you finish, the results screen shows today's rivals — how many players ran the gauntlet in the last 24 hours, the best accuracy among them, and where your eye ranks. Rivals are always anonymous: a count and a score, never names or accounts.
| Adjust | Drag with mouse or finger — every round is one gesture. |
| Confirm | Tap the LOCK IN button. |
| HOLD round | Press and hold anywhere; release to answer. |
Daily gauntlet: 5 seeded rounds, identical for every player worldwide that day. One attempt — your first instinct is the game. Mid-gauntlet progress is saved if you get interrupted.
Practice — the skill trainer: endless rounds, your way. Pick all five mixed or drill a single skill — count, pour, angle, hold or length. Gauge keeps a lifetime accuracy average per skill (from both daily and practice rounds, stored only in your browser), so the picker doubles as your eye profile: it shows your average and round count for each skill, and flags your weakest round from today's gauntlet. After a daily, jump straight into training whichever skill let you down. Every round you finish — daily or practice — also earns eye-rank XP equal to its accuracy: climb a 12-rank ladder from fresh eye through carpenter's eye and hawk eye up to the calibrated. Your rank only ever goes up, and it lives in your browser — no account needed.
Is it free? Do I need an account? Free, no account, no install. It runs in any modern browser, on phones and school Chromebooks alike.
Is it the same puzzle for everyone? Yes — the daily gauntlet is seeded by the date, so your 73% and your friend's 88% came from identical targets.
Does it work in my language? Practically yes — the rounds are numbers and shapes, not words.
