Frost Line
ClassicAn ice-fishing duel for two penguins. Lower your hook, catch the deep fish, reel up before the clock runs out. Play against Popo or against a friend on the same keyboard.
About Frost Line
Frost Line is a two-player ice-fishing game that fits on one keyboard. Each penguin has a single hole and a single hook; holding your key lowers it, releasing reels it in, and anything the hook touches comes up with it. The valuable fish live deep, which means long trips down and long reels back, while the surface is full of quick, cheap catches and the occasional boot. Solo mode pits you against Popo, who plays a fair but beatable game. Sixty seconds, best total wins.

How to play
- Player 1 holds A to lower the hook and releases to reel; S reels extra fast. Player 2 uses L and K. On touch, hold your half of the screen.
- Fish swim at different depths: small fish near the surface for 10 points, squid at the bottom for 80. Boots cost 30.
- A fish is caught the moment it touches your hook, on the way down or up. Reel it to the surface to bank the points.
- Sixty seconds. The higher total wins.
Tips
- Deep squid are worth 80 but take about four seconds round trip. Two surface fish in the same time are worth 20. Go deep early, go shallow late.
- Press the fast-reel key (S or K) the moment you hook something valuable.
- Watch the fish direction; drop the hook ahead of a fish, not on top of it.
- Boots cost 30 points. If a boot is drifting toward your line, reel up and wait.
