How Chess Puzzle Duels Work
Puzzle Duels allow you to settle who has faster tactical vision. Every duel uses a deterministic Room Seed that selects the exact same 5 progressive puzzles (scaling from 600 Elo warmup to 2000+ Elo master tactics). You can play first, lock in your score and time, and send the link to any friend, club member, or Discord channel.
1. Seed Determinism
Both players solve the exact same tactical board positions.
2. Zero Friction
No account creation or lobby waiting needed. Simply click and play.
3. Victory Cards
Generate shareable social cards highlighting the winner and solve times.
