Be a GM

Want to be a Game Master?

Game Mastering a game at COS conventions is always greatly appreciated by everyone involved because it allows everyone, including our volunteer GMs, a fair opportunity to play both new and popular games, as well as entertaining as many gamers as possible!

To help encourage GMs to help make our conventions a success, COS developed a GM Bonuses Program with these benefits for running events:

Earn Free Admission - Online Reg and Onsite
  • •Earn Free Weekend Admission By Running 3+ Events/12+ Hours!
    •Earn Free Friday Admission By Running 1+ Events/4+ Hours!
    •Earn Free Saturday Admission By Running 2+ Events/8+ Hours!
    •Earn Free Sunday Admission By Running 1+ Events/4+ Hours!

Earn Discounted Admission - Online Pre-Reg Only
  • •$20 discount running 2 slot: $15 Pass
    •$10 discount running 1 slot: $25 Pass

  • •Must commit and be signed up for posted events on Warhorn when registration closes (i.e. no backouts after reg closes)
    •Pre-reg is required to ensure players can sign up for the event, (and for organized play events it gives coordinators time to get you mods to be prepared onsite)
    •If the number of GM events do not match the badge fee, you must pay the balance at the door onsite
    •As always, if you pay for any badge but end up GMing 3+ events onsite, we offer a badge refund of fees paid (and many thanks!)
    •As always, if events are scheduled/offered and the GM ready to run but does not due to player lack of interest, there are no drawbacks or reg fees to repay

How Do I Get Started?

Just submit your Game Master Form or submit your events online!
We love having new GMs at our Conventions! Help out, have some fun and sign up TODAY!
