Random events. Say once a month ROBLOX puts a random event on twitter. For example ''Get 100 Total wins in Person299's minigames.'' And when someone completes that they get a hat as their prize.
Comunity events.
ROBLOX Puts a challenge on let's say twitter that the comunity has to complete. Like for example ''Get One million KO's as a comunity.'' Completing this will reward those who participated with let's say a hat, special clothing or something along those lines. |
