Cookie Clicker: best for learning the core loop in your first ten minutes
Platform: Browser, Steam, Mobile · free
What it teaches: producers and multipliers. You click a cookie, buy a Grandma who bakes for you, then a Farm, a Factory and so on, and upgrades multiply what each one makes. Within an hour you will feel the defining moment of the genre: the number you click for becomes tiny next to the number your buildings make. Later you meet your first prestige, ascension, which trades your run for permanent bonuses.
Play it first because everything else on this list assumes you know this loop. The web version is free; the Steam edition is $4.99 and adds cloud saves and mods.
Watch out for: Do not wait for it to end. Cookie Clicker never does. Once you have ascended once or twice, you have learned what it teaches; move on and come back later if you miss it.
