Chessllenge: Online Chess

Chessllenge is online chess where you compete every week — with your friends and with the whole country.

A NEW RACE EVERY WEEK
• Weekly points: win 3, draw 1, loss 0. Your first 20 games each week count.
• Country and regional rankings. Pick your province to compete in your region too.
• Look back at your rank and points from past weeks.

YOUR OWN LEAGUE WITH FRIENDS
• Create a league and share the invite code through WhatsApp, Telegram or SMS.
• Friends join with the code; the league table shows points, wins, draws and losses.
• Belong to several leagues at once: work, school, family.

FAIR, REAL COMPETITION
• 7 time controls: 1+0, 2+1, 3+0, 3+2, 5+0, 10+0, 15+10. Blitz 3+2 by default.
• Separate Glicko-2 ratings for Bullet, Blitz and Rapid; ranks from Pawn to Legend.
• Clocks and moves are verified on the server. Lose your connection and you return to your game.
• Open a private game with a friend using a code.

TRAIN AND IMPROVE
• 1,200 puzzles with hints, undo and an on-board solution.
• 5 bots from 800 to 1850 Elo. Bot games never touch your rating.
• Game history, move-by-move replay, move analysis and PGN copy.

COSMETICS
• Boards and piece sets. Coins are earned only by playing.
• Nothing is sold for money. Cosmetics give no gameplay advantage.

PRIVACY
• No sign-up: we never ask for your name, email or phone number.
• No ads, no tracking.
• Find friends by username and follow them.
• Report abuse in the app and block players you don't want to meet.
