If you have five spare minutes, 2048 Chill will fill them. Everything happens on one screen with a 4×4 board where the target tile is 2048, and the whole thing runs straight in the browser - no downloads, no sign-ups, no fuss.
The strategy sits in corner play: pick one corner, keep your biggest tile parked there, and never swipe it into the middle of traffic. With a 4×4 board where the target tile is 2048, the margin for error changes - more room means longer games, less room means every swipes counts twice.
It suits anyone with a queue to wait in or a kettle to watch: students between classes, commuters, parents stealing ten quiet minutes. There is no meta-progression to lose and nothing to catch up on - a week away costs you nothing but a little sharpness.
