Others may require you issue invoice at the end of each month. The payment may be subject to payment threshold. Though an option to make money, unless you game or app stands it is a bit hard to make enough money.
Selling in-app or digital products
You can limit you game and allow users to unlock by paying a certain fee. This amount is credited to you payment account and payed according to the setting on your account. This depends on how you have coded your game. There are AIPs and SDKs provided by app stores or in-app purchase. One of the best options to make money.
You can show ads on your game or app at intervals. The ads should not affect game play and display. They should also not mask any of the game or app controls. You need to register with ads companies as allowed and approved by specific store you are targeting.
