I keep coming back to browser games that are easy to start but still have enough progression to feel worthwhile over time. Scritchy Scratchy is a good example because it begins with scratch-card style interaction, then expands into upgrades, automation, and longer-run optimization instead of staying flat. It works especially well for short breaks when you want low-friction play without losing the sense that each session moves you forward.

I like browser games that start quickly and still give a satisfying sense of progress. Cookie Clicker 2 is a good example because the upgrade loop stays simple, readable, and easy to return to when you only have a few spare minutes.
