Tourndex implements a modified Swiss pairing algorithm that prevents rematches while balancing win-loss records across all rounds. The engine calculates optimal pairings in under 200ms for tournaments with up to 512 participants, using a weighted scoring system that accounts for opponent strength and tiebreaker scenarios.
Every bracket update propagates to all connected devices within 1.2 seconds using WebSocket connections with automatic fallback to polling. The sync engine maintains consistency across Android, iOS, and web clients simultaneously, with conflict resolution prioritizing the most recent match result submission timestamp.
The double elimination module constructs winner and loser brackets dynamically based on participant count, supporting non-power-of-two entries through automatic bye assignment. Grand finals reset logic is configurable per tournament, and the system tracks full match history including reversed sweeps and bracket resets.
Automated pairing generation for Swiss-format tournaments with configurable round counts from 3 to 11 rounds. The algorithm prevents duplicate matchups while maintaining balanced win-loss distribution, and supports Buchholz and Solkoff tiebreaker calculations for final standings determination.
Generate complete double elimination brackets for 4 to 256 participants with automatic seeding options. Supports winner bracket advancement, loser bracket tracking, and grand finals configuration including bracket reset mechanics. Export brackets as PDF or share live URLs with auto-updating results.
Create full round-robin schedules with automatic venue and time slot assignment. The scheduler optimizes match distribution to minimize participant wait times and supports group stage divisions with configurable advancement rules for knockout phase qualification.
Real-time bracket updates synchronized across all devices within 1.2 seconds. Organizers can manage tournaments from tablets while judges submit results from phones, with all changes instantly visible to spectators viewing the public bracket link on any device.
Manual seed assignment with drag-and-drop reordering or automated seeding based on imported player rankings. Supports regional separation rules, team balance constraints, and historical matchup avoidance for recurring tournament series with consistent participant pools.
Record match scores with configurable best-of formats from Bo1 to Bo7. Track individual game results within each match, assign bye rounds automatically for odd participant counts, and maintain complete match history with timestamp logging for dispute resolution and statistical analysis.
