Clicker Heroes has a very simple premise that actually gets simpler after the first couple of minutes of play. Monsters will be auto damaged and upon their death will yield gold that you can use to increase your auto damage and kill monsters quicker. You can speed things along by clicking for extra damage. You will quickly stop progressing if you are not constantly using your money to upgrade and advance to harder levels. You will have abilities you can use on timers that can massively boost your earnings and damage.
