Pour the SAME amount… into a different glass. Your eyes will lie.

A one-finger pouring game built on a real optical illusion. Five new pours every day, free.

Your brain thinks tall means more.

It's a real perception illusion: tall, thin glasses look fuller than short, wide ones. The same trick is behind Piaget's famous conservation experiment.

Fair Pour turns it into a game: trust your eyes, pour, then let the measuring cylinders tell the truth.

A tall glass and a short, wide glass, each holding the same amount of orange juice. Lulu the cat looks shocked.
Both glasses hold exactly 120 ml.

Quick: which glass holds more juice?

One finger. Three moments.

Hold to pour, let go to stop. Easy to learn, sneaky to master.

  1. Juice pouring from a bottle into a wide glass next to a tall reference glass

    Hold

    Press and hold. The bottle tips further the longer you hold.

  2. Fizzy lemonade foaming as it reaches the target line

    Let go

    Juice already in the air keeps falling, and fizzy drinks foam up. Stop early.

  3. Two measuring cylinders reveal 132 ml against 160 ml: a difference of 28 ml

    Compare

    Both glasses are emptied into identical cylinders. +28 ml? Somebody's crying.

Three ways to pour.

Is Fair Pour free?

Yes. The whole game is free on iPhone, Android and in your browser. The apps are supported by ads, which you can remove with a single purchase.

Are there ads?

In the iPhone and Android apps, yes, but never during the Daily 5 pours. You'll see a short ad every few Café orders, plus optional videos you can watch for rewards like saving your streak.

How do I remove ads?

Buy Remove ads once in the app ($2.99 / €2.99 or the local equivalent). It's tied to your Apple ID or Google account: on a new device, tap Restore purchases in Settings.

Do I need an account?

No sign-up, no email. The game creates a random player ID on your device and you pick a nickname for leaderboards and group leagues.

What about my privacy?

We only keep your random player ID, nickname and scores, so leaderboards and leagues work. No contacts, no location. Ads come from Google AdMob, which asks for your consent where the law requires it. Read the Privacy Policy.

Does it work offline?

Yes, you can pour without a connection. You need to be online to post scores to the daily leaderboard and your group leagues, and to open challenge links.

Which languages does it speak?

English, Italian, Spanish, Portuguese, German and French. The game follows your device language.
