Best Roblox Idle Games
Roblox has a real incremental scene, and almost none of it surfaces in a search for "idle games". The genre label Roblox files these under is Incremental Simulator, the community mostly calls them AFK games, and the good ones sit behind titles like [W2]+1 Drain Water Per Click.
This page is the whole set, ranked by one number: the percentage of Roblox players who gave the experience a thumbs up. That figure comes straight from Roblox's own vote counts and is re-read twice a week, so the order below moves when player opinion does. Nothing here is placed by hand.
A note on what "idle" means on Roblox. Most of these accrue while you sit in the server rather than while you are logged out, which is why they are tagged afk rather than offline progress. Where a game really does pay you while you are away, it says so on its own page.
Playing elsewhere too? The same ranking exists for Steam, browser games and mobile.
