Your initial setup was correct. "The tournament starts" trigger and no conditions. You've configured it correctly. Likely if it isn't firing, it's because you have a different event that is being triggered. Only one event will fire at any time. Events higher in the list will be triggered before events lower in the list. If you've got another event, for example, that plays a sound at the start of a level, it is likely firing, preventing this one from firing. Move this event above the other event. Since it's more specific, it will only fire at the start of the tournament. At the start of other levels, your other event should fire.
