I am making a fps game in which people can join premium matches (to join premium matches player must buy tickets with robux or can win in chests) and the winner gets certain amount of the premium currency(the premium currency is only related to premium matches and can only be used to exchange for robux) which can be exchanged for robux at certain amounts
Do not create promotions offering prizes of any sort (including contests, raffles, lotteries, chain letters or any kind of giveaway). It is okay to offer players promo codes for in-game items only so long as they are not in exchange for something (e.g., in exchange for a thumb up on your game).
Giving away robux is against Roblox’s Terms of Service. Attempting to do this anyway could result in your game being taken down and even further actions towards your account.
No, this system is not allowed and you will get banned. Even if this is possible and you make it you’ll get banned even if you call it a contest or giveaway since those aren’t allowed.
