Monthly official competition
A deeper monthly test of accuracy, composure, and consistent logical solving. New official puzzles use shared conditions so every player faces the same solve, and final standings publish only after careful integrity review.
Tournament structure
The lobby shows authoritative start and close times for entry, each official round, and the verification period.
Each official puzzle follows the announced attempt, tool, and submission limits. No hints, no live mistake checking, and one submission per round.
Standings publish after integrity review and appeals, and finalized results contribute to tournament history and the Global Ranking.
