Run a penguin across the ice from one research station to the next before the clock runs out. The road winds over the snow in pseudo-3D: jump the holes and the cracks (fall in and you lose seconds climbing out), steer round the seals that pop up, run through the flags and catch the fish leaping out of the holes in mid-air. Every second left at the station is a bonus — and each leg is longer and tighter. Free, no sign-up — play right in your browser.
