If you have a mid-range phone or computer you can play for real money. All you need is an up-to-date version of your internet browser, such as Firefox or Chrome, and no additional software to install. Very few older games may only require Flash, but less than one percent of slots are affected. Developers also optimize games in such a way that they run on weaker hardware, and even so that they do not use a large amount of network data. As a result, you can easily play even with limited Internet speeds, for example on LTE networks.
