I love dynamic games where the outcome depends not only on luck but also on your reactions. Are there such formats among online games today? Or are most of them purely random? I'd appreciate any recommendations.

If you're looking for action, those games exist - you just have to find them. This site features a fascinating batting game . There are also specific categories where everything happens quickly and requires quick reactions. I sometimes go there myself when I don't have time for long sessions. In one case, I managed to nearly double my deposit in a short session. I then processed a withdrawal without any problems, and the money arrived fairly quickly. These formats are great for adrenaline-seeking players.
