Built on Google Cloud Firestore, ChessHub delivers low-latency matchmaking across three official time formats with live board state replication, FEN generation, and FIDE-compliant clock expiration.
60-second sudden death clock. Test your instinctive calculation, fast pre-moves, and tactical speed flags in the most intense chess arena.
The gold standard of competitive online chess. Fast tactical maneuvering with enough room for profound strategic planning and sacrifices.
Deep positional calculation, complex middle-game imbalances, and refined endgame execution. Full FIDE move compliance and cloud archive.
Turn any iPhone, iPad, or Android phone into a professional competition chess clock. Play over your physical wooden board with custom time controls, move count tracking, and independent device sound muting.
Isolated Audio Control: Local acoustic piece clicks. Muting sound on your device has zero effect on your opponent's device.
FIDE Clock Expiration: When a player's countdown reaches 00:00, the clock sounds a termination chime, registering a loss on time.
Select a character persona representing your playing style. Each persona features custom 3D animations, title badges, and signature tactical philosophies.
Exclusively real players and verified real ELO points. Zero mock or simulated bots on the leaderboard. All ratings are calculated using standard FIDE K-factor formulas (K=32).
Engineered for seamless cross-platform performance across iOS & Android.
