About this game

Lay the pipes, light the cabins.

A snowstorm has frozen the village. Your furnace still burns, and only you can carry its heat through the snow. Heat Lines is a cozy connect-the-pipes puzzle: lay copper pipes from the furnace to every frozen cabin and watch the windows glow again.

A PIPE PUZZLE THAT MAKES YOU THINK
Like a classic plumber puzzle, but with heat instead of water. Every level is a fixed, fully visible logic puzzle. Nothing is random: you see your pieces coming and plan the route. Turn the pipes, branch the heat with T-junctions and crosses, and warm every cabin before your pieces run out. Use fewer pieces to earn three stars.

NEW IDEAS AS YOU GO
• Ice blocks melt when heat reaches them, opening new paths
• Rocks force you to find another way
• Old pipes carry heat, but they won't move
• Lodges need warmth from two sides
• Two furnaces, one board

WARM UP THE VILLAGE
Earn Embers by solving levels and spend them on ten buildings that work for you: a bakery that bakes free hints, a blacksmith that forges Wildcards, a post office with a daily parcel, and more. Level them up, add 24 decorations, and unlock new pipes and board colors as your village grows warmer.

A DAILY PIPE PUZZLE
A new puzzle every day, the same for everyone. Solve it to keep your streak burning and earn bonus rewards.
