The official events in the ingame shop. The game sorts them by level, then price, 6 per page. Staff events only show for staff. Unticking "Shop" keeps an event official (it loads like a shop event) without showing it.

Hidden events that start by themselves in every room at the same moment (not in friendly places like the shop, not between arcade rounds, not while another event runs). "Every" 6 means once in every 6 hours, at a random moment, so about 4 times a day. Hours are German time; the same hour in both means all day. They must be public mods on mod.io so every player can download them.

Paste a mod id or a mod.io link, or search the game's events.
