Puzzle — Genre Overview

Puzzle games in the browser span everything from three-minute word grids to hour-long escape rooms that demand graph-theory thinking. The best ones signal their own difficulty ceiling within the first thirty seconds — you know whether you are dealing with a gentle crossword warm-up or a constraint-satisfaction nightmare before you invest. Bramwell Faucher's test-rig consistently ranks puzzle as the genre with the highest retention on mobile keyboards, because one-handed play rarely demands split-second timing.

Session Length

5–45 minutes typical.

Editorial Note

Avoid anything marketing itself as 'brain training' — the science behind those claims collapsed in 2014. The games are still fun; the medical promises are not credible.
