Slope 3 continues one of the most-played browser games there is: a ball rolling down an endless neon track, steering left and right to stay on it while the speed climbs without limit.
The genius of Slope is that it never asks you to do anything complicated — just don't fall off. What makes it hard is that the speed keeps rising until your reactions can't keep pace, which is a difficulty curve nobody has to explain.
Look far ahead rather than at the ball, and steer with short taps rather than held keys. At high speed, a held input crosses the whole track before you can correct.
No — it's endless, with the speed increasing until you fall off. Distance is the score.
Yes — one of the most popular games on school machines, and it runs in the browser with nothing to install.
