Sends this puzzle’s number, your screen size, browser and app version so we can reproduce it. Nothing that identifies you.

Five things to judge by eye, dealt each day from twelve kinds. One guess each — then the truth is drawn over it.

Some rounds are dialed. Slide to your estimate — how many dots, what percent, how many degrees, how many times bigger or longer. The − and + buttons nudge it one step.
Some are placed. Tap or drag on the picture — where a circle’s center is, where an arrow lands, where two lines would meet, where the average sits.
Count shows its dots for three seconds, once. Look first, then answer.
Lock in commits the guess. A round scores 100 for a guess within a small margin of the truth — you never have to be perfect — and falls steadily to 0 for a wild one.
Your score for the day is the average of the five, out of 100.

One set a day. Your scores are kept — Statistics is in the menu — and Eyeball sits outside the daily line-up, so it never moves your day’s total.
