Roblox playable on PS4?

I have a question and can you play the game roblox on the ps4 or are there any apps that I can use to link my TV to my cell phone and use it to play on the TV?

It is playable on ps4 and played with a friend

but kp how it works.

And if you have an Iphone and your TV is a fairly new TV that can connect with Bluetooth etc., then you can do that through screensharing, which can be seen below when you swip up

So there's no roblox as the original PS4 game. Still seems to be possible anyway. Have a look on YouTube
