Action games are free online games to play where you must react quickly and think fast. You play as a hero who has to beat enemies or avoid traps. To win, you need to be quick and clever. These games come in different styles, but all need speed and good timing. Some games are about fighting, while others are about jumping over things. They keep you focused and help you make fast choices. You can play alone or with friends, and the games get harder as you get better, which makes them even more fun!
