How perfect is your cut?
Pick an object. Drag one line across it. The moment you let go, 50/50 measures the two halves against each other and tells you exactly how close you came — to two decimal places.

OFF← drag the line →We make small games with one rule and no forgiveness — cut an object exactly in half, tap at exactly five seconds, land exactly one jump. Every one of them is playable in your browser before it reaches the App Store.
What we make
A game should ask you for one thing and then be completely honest about how well you did it.
One rule
If a game needs a tutorial, we have already lost. Cut it in half. Tap at five seconds. Jump.
Real numbers
Scores are measured, not awarded. Two decimal places is enough to keep you honest and enough to keep you playing.
Nothing collected
No accounts, no analytics, no ads, no tracking. Your scores live on your phone. That is a design choice, not a roadmap gap.

A circle, already halved. The whole game in one mark.
Pick an object. Drag one line across it. The moment you let go, 50/50 measures the two halves against each other and tells you exactly how close you came — to two decimal places.
Every object cuts differently
A cookie forgives a wobble. A donut punishes one, because the hole moves area away from the middle. Learning which shapes lie to your eye is the whole skill.
Measured, not guessed
Your line is scored on true area on each side, not on where it crosses the center. Two decimal places, so there is always a better cut than the one you just made.
Three cuts a day
Attempts are limited and reset daily, which makes a good score worth keeping and a wasted line genuinely annoying.
Progress that stays yours
XP, unlocked objects, and your personal best live on your device. No account, no sign-in, nothing uploaded.

ON THE DOT
Five seconds. No clock.
Set a target — five seconds, or eleven, or twenty-three. Start it, and the clock disappears. Tap when you believe the time has run out. You find out how wrong you were in milliseconds.

REX
One button. Keep running.
Rex runs on his own. All you do is jump. Cacti come, then they come faster, then they come in pairs, and the only thing that ever ends a run is you being early or late.

The studio
WAAI GAMES
One-thumb games about getting it exactly right.
We are a small independent studio building for iPhone, with 3 titles in the catalog and more in the queue. Everything is built in-house — design, code, sound, and the maths that decides whether your cut was good enough.
Scope
Small on purpose
Every game here is one mechanic taken seriously. That is a ceiling we chose, not a budget we ran into — a game you understand in three seconds has nowhere left to hide.
Data
We collect nothing
No accounts, no analytics, no advertising SDKs, no tracking. Progress stays on your device. It makes some things impossible, like global leaderboards, and we would rather lose those than ask you for anything.
Method
Playable before it is pitched
If a mechanic does not survive a browser prototype, it never becomes an app. Everything on this site you can play is the same code path we ship.
