Four Competitive Match Formats. One Unified Engine.
CP Duel decouples room management, unsolved problem selection, and submission tracking from scoring strategy.
1v1 Blitz Duel
First-to-solve speed sprint. Both players share the same active problem. The first accepted submission captures the point and automatically unlocks the next challenge.
ICPC Contests
Traditional collegiate format. Multi-problem catalog accessible from the start. Rankings decided by solved count and time penalty with incorrect attempt additions.
Team Battle
2v2 or 3v3 team skirmishes. Roster submissions are aggregated into a single team entry score, enabling true collaborative problem distribution and strategy.
Knockout Brackets
Single-elimination tournaments. Automatic seeding, bracket progression, and synchronous round launches with live spectator commentary and audit logs.
Compilation Error Verification & Unsolved Problem Selection
To prevent alt accounts and unfair advantages, CP Duel verifies Codeforces handle ownership by requiring a one-time Compilation Error (CE) submission on a randomly assigned problem within 10 minutes.
Zero Solved Problems Pool
Our worker synchronizes participant submission history. Duels never draw a problem that either contestant has previously solved.
Earliest-Verdict Arbitration
In Blitz duels, tie-breaks use Codeforces submission creation timestamps and IDs, ensuring polling order never skews the legitimate winner.
