How to promote an online casino now that Google Ads bans brand keyword targeting for gambling?

A few years ago I spent $60 on Google Ads and ran ads for a casino on a brand keyword. I attracted 19 players and over a couple of years made $900 back from them. That's the kind of thing you used to be able to do on Google — unfortunately now it's banned.

On Meta Ads, I don't think it really makes sense to try the same approach, because there you get paid based on the user's wager, not CPA per deposit. Google was an ideal method for promoting this type of offer.

Can anyone recommend an alternative way to promote this kind of casino? I understand that search intent on Google was ideal for this, but it's no longer allowed — is there another way I could approach this?
