In most cases, you can use the welcome bonus of a casino from your mobile device. Seeing how most casinos have mobile apps that players can use, you can also benefit from the exclusive offers that are only available if you use their app. You should, however, make sure that you know the details and requirements for using any bonus before you deposit your money. If there’s a requirement that the casino has and you fail to fulfill it, you can miss out on some great bonuses and promotions in the form of gaming money or free spins.
