How to play
- Out on the sea ice, the penguins' nests sit on the far shore, past a busy research station. Hop each penguin home across the ice road, then across the open water, into one of the five pebble nests at the top.
- Hop one square at a time with the arrow keys or W, A, S, and D. On a phone, use the four buttons under the picture, or swipe on the picture. You can press once ahead during a hop, and it will go next.
- The ice road carries snowmobiles, sled trains, fuel sledges, and the big snowcat. A bonk costs a penguin. The water lead has no bridge: ride the white floes and the backs of resting seals. Seals blow bubbles for a second before they dive, and the current sweeps away any penguin that misses its footing or rides off the edge.
- Each penguin has 30 seconds of warmth, shown in the meter. A nest that already holds a penguin, or a snowdrift between nests, bonks you. Fill all five nests to end the day; the next day's traffic and current run 12 percent faster.
- Scoring: 10 for each new furthest row, 50 for a penguin home, 10 for each second of warmth left, 200 for a pebble carried home, and 1,000 for filling all five nests. Step on a pebble lying on the snowbank or the road to pick it up. You start with four penguins and earn another every 10,000 points.
- Press P or Esc to pause and M to mute. Enter starts the game and the next day. The game pauses itself when you switch tabs.
