Question 1

What is Smile?

Accepted Answer

Smile is a browser page filled edge to edge with emoji. You can match identical pairs to clear them, or leave it in Meditate mode and watch the faces drift, trade places and breathe on their own.

Question 2

Is Smile free and does it need an account?

Accepted Answer

It is free, carries no advertising, and needs no account or installation. Everything runs locally in the browser.

Question 3

Can the game be unwinnable?

Accepted Answer

No. The field is always built from complete groups, so every face on screen has its partner and the board can always be cleared.
