So, it says that there will be no local rules that will be violated if a local plays from there and they have a mirror link that's dedicated for PH users.
That's actually a great option since it's safe. However, there are already several casinos accessible in the Philippines that accept GCash as a payment method. Some platforms I'm familiar with include 1xBet (though it has a questionable reputation in this forum) and BK8. This availability isn't really surprising, perhaps many of us just haven't explored enough options yet.
1xbet has a popular platform and has no direct accusations cases against them here in the forum, the only question of reputation is just a suspicious likeliness to 1xbit which is a scam casino.
So in essence, 1xbet can still be referred to others if you feel that they have services that could meet the desire of the ops.
