I do not think anyone has really mentioned this, but I am pretty sure roulette was deleted in the mini-games channel ever since there was suggestion to remove it for being violent and not family friendly. I do not know why it still appears in the games section, but that should be removed if it is no longer available.
It is an understandable change, but I still kind of liked how the mini-game of operated and it was very rewarding than the other mini-games, I think. I think either a mini-game that functions exactly like roulette, except this time, it does not use a gun. Or a new mini-game should be added, since removing one mini-game reduces the variety of mini-games. Also, put emojis back in too (different ones), those were visually suspenseful in roulette.
