Ninety-Nine

Tiny tests of precision.

Ninety-Nine: Perfect Games is a free iPhone and iPad game: a notebook of tiny tests of precision. Draw, split, pour, fold and tap. Most take a few seconds, and the precision rounds are graded like homework, out of 100, against a mathematically perfect attempt.

Nobody gets 100.

Free. No ads, no in-app purchases, no account.

Drag a loop with your mouse or finger. It is scored by the app’s own code.

Pick a challenge.

Each takes a few seconds. Precision rounds end with one honest number from 0 to 100 and a short note on what went wrong. Pick the Wrong Color counts your right answers, and Stickman Battle counts the hearts you have left. Tap one to play a round of it here.

Graded like homework.

Your stroke is measured against the circle you meant to draw. Closure, radius consistency, coverage, smoothness and steadiness are scored separately, then weighted into one number — so a circle that looks right can still lose points for a gap at the ends or a wobble down one side.

Carrying on a little past where you started is how people close a circle, so that overlap is trimmed before anything is measured. Then the result is written, circled in red pen and stamped, with your line drawn under the ideal shape and one plain note on the thing to fix first — left 12° open, a bit oval, flat at the top-left.

The scorer measures your attempt against a mathematically perfect one. Hands are not mathematically perfect.

A Perfect Circle result screen: the drawn circle under a dashed red ideal, the score 99 circled in red pen, stamped PERFECT, with a new best sticker.
The Share the score sheet: a report card reading Perfect Circle, 99 out of 100, circled and stamped PERFECT, with Save and Share buttons beneath.

Send the proof.

Turn any result into a notebook-style score card, then send it through the share sheet or save it to Photos. Pick a layout, then a paper: white, highlighter or night.

Report card
Graded, circled and stamped.

How close you came to perfect.
Head to head
Your score beside an empty slot.

Nothing is shared unless you tap it. Saving only adds the card to your photos; the app never looks at the rest of your library.

A closer look.

Stickman Battle on a phone turned sideways: your three stickmen on the left page, Scribble's three on the right, the notebook's rings down the fold between them.

Fold the page. Stamp their stickmen.

Stickman Battle, against a rival that gets sharper every win.

Aim on your page, fold it shut, and your paint stamps onto Scribble’s page, mirrored. Knock out all three of its stickmen before it gets yours. This one turns your phone sideways.

Coming to iPhone Duo: you fold the phone itself. Try it in your browser.

Brain Power and streaks

82

Brain Power

Your skill meter, 0 to 100. Great rounds add up to +5, sloppy ones cost up to −4, and it fades −3 for every day you skip.

7

Day streak

Days in a row you have played. One round a day keeps it burning; miss a day and it starts over.

Both live on your device, and nowhere else.

Made to be quiet.

Your scores live in the app and nowhere else. Nothing is collected, and nothing leaves your device unless you share a score card yourself — which is also why the privacy policy is so short.

It fits in a pocket of spare time: waiting for coffee, sitting on the bus, or the last thing before bed.
