Run 3 is a free online running game in which you try to stay on the track for as long as you can. At first, the gaps in the tunnel are easily avoidable, as you can spot them from afar. But as you keep running, the challenge increases. Those easily spotted gaps show up more frequently. Not only that, since you've gained quite a bit of speed, they also come at you much faster. Be careful, though, if you make so much as a single mistake you will lose your footing and fall through space with no end in sight.
Controls: Arrows = Right / Left, Space = Jump
