Question 1

Is this game really free?

Accepted Answer

Yes. There are no ads, no signup, and no in-app purchases. Just play.

Question 2

Do I need to install anything?

Accepted Answer

No. It runs in your browser, on phone, tablet or desktop.

Question 3

How does multiplayer work?

Accepted Answer

Create a room, share the 4-letter code, and your friends join instantly. Up to 20 players see the same grid and compete for the fastest time. Each round cycles through 7 game modes in a random order.

Question 4

Is my progress saved?

Accepted Answer

Yes — your solo mode progress (stars, best scores, streak) is saved on your device locally. No account needed.

Question 5

What is 'find the odd one out'?

Accepted Answer

It is a classic visual puzzle: a grid is filled with copies of one image, and only one cell has a slightly different version. Spot it as fast as you can. Q-Desafío adds 8 game modes that twist this concept (memory sequences, mirror images, sudden death, multiple targets, and more).

Question 6

What languages are supported?

Accepted Answer

13 languages: English, Spanish, Portuguese, French, German, Italian, Chinese, Japanese, Korean, Russian, Arabic, Turkish, and Hindi.
