Of course not so popular like in the US, but it has some players, and was starting to grow.
Most european countries have laws giving landbased casinos exclusive rights to gambling, but there is “an hole” in the european law, stating that if a casino has business in a european member country, they can also work in the others.
It’s a mess, and I don’t know for how long it will last.
Of course some will continue, like RTG is doing, but we never know the future…
