Nobody gets 100.

Every precision game in Ninety-Nine measures your attempt against a mathematically perfect one. A 100 is possible in every one of them. Here is exactly what it takes, game by game, straight from the scoring code.

From the app's own scoring code, as of September 2026.

What 100 takes

GameFor a 100
Perfect CircleAll eight measurements at their best at once, nothing capped and nothing taken off
Perfect TimingStop within 10 ms of 5.000 seconds
Perfect CenterDrop the dot within 2% of the shape's radius from its true center
Perfect SymmetryKeep your line within 0.6% of the shape's diagonal from the true mirror
Perfect StopStop within 8 ms of dead center
Perfect FillStop the pour within 16 ms of the line
Perfect HalfCut within about 0.3% of an even split
Pick the Wrong Color100 right answers

Stickman Battle isn’t scored out of 100. It counts the hearts you have left, from 0 to 3.

Why the windows are so small

In Perfect Fill and Perfect Stop, the screen sets the window for 100. A 60 Hz screen draws a new frame about every 16 ms. A pour stopped within one frame of the line, or a stop within half a frame of the center, is as close as a standard 60 Hz screen can show.

So does anyone get 100?

Every window above is real, and every one of them can be hit. All it takes is a hand exact to a few milliseconds, or to a fraction of a percent. Nobody gets 100. Prove us wrong.
