If you are playing in official servers (Beginner, Intermediate, Semi-Pro, Blackbelt) then the servers are messed up.
If you are playing in your own room or somebody elses, then you do not get toricredits for a win. The reason you don't win toricredits in personal rooms is because if they did that then people could set up rooms to mods that lasted 1 or 2 turns, and farm toricredits.
