english is not my first language and the credit system is hard to understand. i spend the credits but i dont know always what they are for. i asked support to explain and they sent me a page that explain in english that is difficult. better explanation would help people like me.
On topup.pk I chose my game, entered the player ID, and picked a local wallet. Credits landed in under a minute. Instructions warn not to share OTPs, which I appreciated. Smooth flow.
