Official Tournament Rules

Here, only official Tournaments organized by the Duelists Unite team will be posted. This may include tournaments on YGO Omega as well as our partner simulators like Dueling Nexus.

All tournaments are Single Elimination. Decks are locked and cannot be changed once the tournament begins (this is automated in YGO Omega). There is no End of Match Procedure (EOMP) or a round timer. In real life, EOMP exists to finish a tournament within a round timer of 40 mins. For online simulators, we don’t believe this will be an issue as the time per turn will be 180 secs (3 mins). EOMP has been abused in real life encouraging intentional slow play or use of LP modifying cards. We do not believe that EOMP accurately determines the true winner and is not needed in an online system.

We also cannot do Swiss rounds online as it is not practical. Swiss rounds are done in real life because these tournaments can be 2-3 days. Our tournaments are live and finish on the same day. Konami previously hosted official online tournaments on their simulator, Yugioh Online where they used Single Elimination with 512 participants max. We do believe that this system works as it has been tested and worked before. No system is perfect and all tournaments are just an approximation of the true winner. The ideal system is Round Robin (everyone duels everyone), but the number of permutations for that is also not practical. To read about how tournaments work in real life, read here.


Number of Players in tournament (N) and Number of Players in Queue (Q)

  • Rounded down to the nearest power of 2 where N = 2^{\lfloor \ln(Q) \rfloor}
  • Players in queue that exceed N, will be kicked out and not included.
  • Maximum capacity is 512. (We can consider doing larger in the future)
  • Your position in queue matters. It’s first come first serve. Joining the queue is analogous to registration of your deck. You must leave queue and rejoin if you wish to change the deck.

We may also do it on weekdays. The dates will be announced on the calendar in this site. We’ll rotate through all time zones so that everyone will have a chance to play.

YGO Omega Championship (YOC)

At the end of the season (~1 year), we shall host a YGO Omega Championship (YOC). This will occur around Winter or December. There are two ways to get an invite - through TP or YOCQ.

Tournament Points (TP)

Only TCG, OCG, or WCS tournaments will count towards points. TP will be awarded as follows:

  • TP = 1+ \sum _{k=0}^{n} \frac{k(k+1)}{2} where n=# of consecutive match wins in a tournament.
  • For example, if a player won 0 times in a tournament, then TP = 1 point for participation
  • If a player won 1 time, then TP = 1+1 = 2; won 2 times is TP = 1+1+2 = 4; won 3 times is TP = 1+1+2+3 = 7 points and so on. This is basic summation series.
  • The 1st place winner of a tournament with 5 rounds of 32 players, gets TP = 1+1+2+3+4+5 = 1+ \frac{5(5+1)}{2} = 16 points.
  • The 2nd place of that same tournament will get
    TP = 1+1+2+3+4 = 1+ \frac{4(4+1)}{2} = 11 points.

TP will be cumulative for the duration of the season (~1 year). The players with the highest TP (~top 448), will be invited to enter the YOC in December to compete under the WCS banlist.

Note that TP is separate from Elo. The Elo points are gained in ranking per format. Ranking seasons are shorter and are consistent with the frequency of banlists (~3 months). Elo will not be factored into gaining an invite to the YOC.

YGO Omega Championship Qualifier (YOCQ)

We realize that not all Players will be active to accumulate TP, so they can compete in the YOC Qualifier (YOCQ) and the top 32 players would receive invites to YOC despite their TP. There would be one YOCQ for TCG and OCG a week before the YOC.

We designed this point system after reading how points work in real life for both TCG and OCG. We do believe this is a consistent system that will work for all players online.
