Konami Card Game Network (KCGN) Information


Beginning March 23, the new Konami Card Game Network (KCGN) will be launching and replacing COSSY. All COSSY services will be suspended on March 22, 2017 for data transferring to the new system. You will still be able to use COSSY until March 22, 2017.

KCGN will offer the same features that COSSY did, but now will allow you to assign a home store and get ranked within tournaments run at your home store. KCGN will also be compatible with Chrome and Smartphones
We will post more information on this page soon, please check back after March 23.

Konami Card Game Network KCGN



Each quarter will be filled with thrilling Sanctioned premier level tournaments, local events and Regional Qualifiers – enough to satiate every level of the Yu-Gi-Oh! TCG Duelist.

Prizes will be given to those Duelists who participate in Sanctioned tournaments during the qualifying quarter, and finish among the top ranked Duelists in their COSSY region.  For the Americas, we will be awarding prizes to the Top 500 Duelists from the United States, Top 50 from Canada and the Top 100 from Latin America.  To be eligible for prizes, be sure to register your personal information at https://www.cossy.konami.net/, so that we can mail your prize to you.


To make sure everyone gets a chance to earn their way up the rankings, KDE needs your help.  Duelists need to get their local stores on board with COSSY, as in some cases, this is the only way for Duelists to earn COSSY points. Duelists will get a real sense of where they rate and stores that utilize COSSY will enjoy stronger Yu-Gi-Oh! participation from their player base.  Sanctioned tournaments using KTS, such as the Regional Qualifiers, count toward your rankings too, as long as the results are submitted to KDE!

Find an Official Tournament Store (OTS) near you and start Dueling!
