Android & iOS
Competitive chess,
with transparent rules.
The rules of chess don't change. What changes is that rating, matchmaking and progression are fair and open. No ads, no tracking, no pay-to-win.
Free. No sign-up — open the app and play.
Time controls
Three formats, three separate ladders
Each format has its own Glicko-2 rating. A blitz game never touches your rapid rating, so the tempo you're actually good at doesn't disappear behind a single number.
2 minutes, 1 second added per move.
3 minutes, 2 seconds added per move.
10 minutes, no increment. Pure calculation.
Features
Not an app that ends when the game does
Real-time games
The clock and move validation run on the server. Lose connection and your game is still there when you return.
Glicko-2 rating and ranks
Seven ranks from Pawn to Legend, three divisions each. Rating uncertainty counts — a few lucky wins won't carry you to the top.
Training bots
Five bots from 800 to 1850 Elo, each with its own style and favourite opening. Take moves back against bots; your rating is untouched.
Puzzles
Tactics training with a separate puzzle rating that adapts the difficulty to you.
Tournaments and seasons
Arena tournaments, seasonal resets and season-exclusive cosmetic rewards.
Post-game analysis
Replay a finished game move by move, see the critical moments, revisit any past game.
Daily quests and achievements
Quests that refresh daily, long-term achievements, and coins to spend on cosmetics.
Player profiles
Search players by @username, follow them, build a friends list; your profile shows your rating history and achievements.
Five languages
Turkish, English, Spanish, Hindi and Russian — picked automatically from your device.
Fair play
Competitive means protected
A rating ladder is only worth climbing if nobody can take a shortcut up it.
- Server-authoritative: moves and clocks are validated on the server, not the client — a modified client gets you nowhere.
- Collusion detection: repeated suspicious pairings used to inflate rating are flagged automatically.
- No engine assistance: using a chess engine in human games leads to a permanent ban.
- Bot games are unrated: training never pollutes the ladder.
Privacy
We don't know who you are, and we'd rather keep it that way
Playing requires no name, email or phone number. Your account is an anonymous guest account; there is nothing on the server that identifies you.
- No ad networks — nobody is shown advertising
- No analytics or usage-tracking SDK
- No data sales or sharing for marketing
- No location, contacts, photo or microphone permissions
One exception, stated plainly: on Android we receive a technical crash report if the app closes unexpectedly — a crash on your phone leaves no trace on our server, so there is no other way for us to see the bug. What the report contains is in section 4 of the Privacy Policy.
You can permanently delete your data from inside the app at any time — no forms, no waiting for an email. How to delete your account →
Questions
Frequently asked
Do I need an account?
No. The first time you open the app the server creates an anonymous account for you and gives you a recovery code. No email, no phone number, no password.
What is the recovery code, and what if I lose it?
The recovery code is the only key to your account and the way to move it to a new device. The server stores only an irreversible digest of it (SHA-256) — we cannot see the code itself. So if you lose it and also change devices, we cannot restore your account. Save the code somewhere safe.
Is it paid? Does paying give an advantage?
The app is free and there is no pay-to-win. If cosmetic (visual only) purchases are added later, none of them affect playing strength.
Do bot games affect my rating?
No. Games against bots sit entirely outside rating, ranks and the leaderboard — which is exactly why you can take moves back in them.
How do I report a cheater?
Write to the address on the support page with the opponent's username and the date of the game. Automatic detection already flags suspicious patterns; your report strengthens the review.
How do I delete my account and data?
In the app: Profile → Danger zone → Delete account. It is immediate and irreversible. Details and the email route: Account deletion.
