I found this one gametype online that allowed 10 frames to pass the first few turns and incorporated a gradual increase of frames in the turn to, 20, 30, 35, 40, etc. How do I set this option in the create-a-server list?

You type a comma between the turns.
Example: 10,20,30,40,50

Create-a-server list?
