Why Micro-Sessions Win at Work

A break is measured in minutes, so the ideal game is one you can start, enjoy, and stop cleanly. Instant-play browser games are engineered for exactly that rhythm.

Short, self-contained loops fit the workday better than long campaigns. See how session lengths vary in our gaming time and engagement report.
