Simulation — Genre Overview

Simulation games in the browser range from the reassuringly gentle (Hay Day–style farm management) to the perversely complex (OpenTTD in a browser tab). The genre's strength is that it tolerates interruption: you can close the tab, come back, and the system has simply evolved. The weakness is that most browser sims either monetise aggressively or are Flash-era relics that no longer run. The ones that survived to 2025 on HTML5 tend to be the ones built by people who actually liked the genre.

Session Length

10–120 minutes typical.

Editorial Note

Mini Metro is the best pure-mechanics simulation in the browser. It is also one of the few games in any genre that has a meaningful accessibility mode.
