This game is #1 on the US Casino charts. The description claims "Cashing out your Solitare winnings is easy, safe and secured by PayPal. We also partner with Apple Pay, Visa, Mastercard, and American Express to make the deposit and withdrawal process secure and easier." If this is in fact true, how on earth do they achieve withdrawing real money winnings while adhering to US law? Stranger, the developer seems to be incorporated in the US and raised $40M in funding. https://www.pocket7games.com
