We live in a world of fun and fortune. There’s no difference for us whether our players are from.
That’s why prices in the game are set in US dollars only.
 
But it seems your payment providers have another opinion on this matter and automatically convert the price into the player's local currency. That’s where the difference comes from.

We only receive the advertised amount which you see in the game. If the actual amount differs from this, please contact your payment provider and check all the details.
