Questions, answered.
Is Kwazy free?
Yes. Kwazy is free to play: no coins, no shop and no subscriptions at launch. There’s no real-money play, ever.
Do I need to download anything?
No. You can play a duel in your browser straight away and save your progress later with your phone number. The iPhone and Android apps add notifications and a faster keypad.
Which phones does it work on?
Recent iPhones and Android phones, plus any up-to-date browser on a phone, tablet or computer.
Do I need to be good at maths?
Not at all. Every game has its own rating, so you’re matched with people at your level. And there are word, logic, memory and puzzle duels too.
Who is Kwazy for?
Anyone 13 or older who likes quick brain games and meeting people who think fast. Players under 18 join with a parent’s okay.
How is it different from other brain-game apps?
You play real people, one on one, for a minute. Every match ends with a human next step: add them, rematch, or review your answers. No feeds, no swiping.
How long is a duel?
One shared 60-second clock. Most correct answers wins.
How does matchmaking work?
Tap a game and Kwazy finds someone near your rating, usually within ten seconds. If nobody’s around, Kwazy Bot steps in for a fair practice round.
How are ratings worked out?
Like chess: an Elo rating per game. Beat a stronger player and you climb faster. Your first 30 games in a mode move it more while it settles.
Who can message me?
Only friends. Chat is text only: no photos, voice notes or links.
What’s different for under-18s?
Adults can’t send them friend requests, strangers see less of their profile, phone numbers can’t be shared in chat, and a parent approves the account.
Can I block or report someone?
Yes, from their profile. Blocking hides you from each other and removes the friendship.
What do you use my number for?
Only to sign you in. It’s never shown on your profile.
Is my location shared?
Never exactly. Kwazy only ever uses an approximate city, and you can play without sharing it.
Can I delete my account?
Any time, in Settings. You get 30 days to change your mind, then your profile, ratings, friends and chats are erased.
Calm mind. Sharp brain. Good company.
A minute of Kwazy is a workout for your brain and a hello to someone new.
