Roobet on Solana?
It looks like someone is trying to milk out from a big brand like Roobet by creating some token on Solana and listing it on dexscreener

They have a weird URL for their website (roobetsol.xyz) but then go on to add the official link on the website. Is there any official collaboration, or this is just memes as usual?

It's obvious that this is a scam. They'll ask you to connect your wallet and if you have any crypto on that wallet, they'll drain it. First of all, Roobet has not announced anything about their token on Solana network or any other blockchain network and I don't think they have created their own token like other casinos. This incident of fake tokens also happened recently with stake.com and there was even a post here on Bitcointalk. Good thing the moderators acted quickly and deleted the post immediately.
