An incremental, Idle, or clicker game is a video game genre. An incremental game is played by doing simple things such as clicking on the screen and watching numbers go up.[1] One popular idle game is Clicker Heroes.[2]
In some idle games, even the clicking is no longer needed after some time, as the game plays itself.[2]
You can also "ascend" to essentially start over, but you'll unlock more special powers in the process.
