01 / On the ice

Your friend.
Your brake.

There's no steering halfway through a slide. Look at the whole hill before you give that first push.

The way home is a small puzzle of big consequences. Push a kid in one direction and they keep going until a stopper catches them. A rock. A snowbank. A snowman. Or another kid, parked in just the right place.

Switch between the sledders to build a route, one stop at a time. Every empty hut catches a kid. Fill them all to clear the puzzle.

Sometimes getting home means sliding back out again.

First Glide on Frostbank: one push has carried a kid into the right-hand hut, which sparkles. The second kid waits on the left.
1Plan the landing.

Look for the next stop, not just the hut. A push keeps going until the hill, or another kid, gets in the way.

Find the stopper first. The hut comes second.

Make Room for Three on Driftwood, solved: all three kids tucked into sparkling huts among rocks and snowbanks.
2Make room.

Three kids, three huts, everyone home. Once a kid is inside, they become a stopper for the others. Switch to that kid and slide back out when someone needs a helping hand.

A full hut is a roadblock. Slide that kid back out when it's in your way.

The stopping crew

Rocks · snowmen · snowbanks · other kids · empty huts. A full hut is a kid-sized roadblock.

Pause

Playing in the browser? Arrows slide · Tab switch · Z rewind · X choose · Enter pause. On a phone, the buttons appear on screen. In your own emulator, the keys are whatever you set.

  1. Push once. Find the stop.

    The D-pad starts a slide. Rocks, snowmen, snowbanks and other kids stop you. You can't steer halfway through.

  2. Get everyone home.

    Empty huts catch kids. Fill every hut to clear the puzzle. A kid inside blocks others, and can slide out again to help.

  3. Leave a crack behind.

    Thin ice opens into a hole after a kid slides off it. That route may be gone on the next pass.

  4. Read the warning.

    Heading for a hole? Press B during the warning to cancel. If you wait, the sled keeps going.

  5. Take it back.

    B rewinds a slide, even a fall. Try another stop or switch the order. You don't have to start over.

  6. Then chase the star.

    Getting everyone home clears the puzzle. Beat par for a star. That one unnecessary slide is suddenly going to bother you.

03 / The long way home

Four hills.
Sixty little knots.

Fifteen puzzles on each hill. The snow changes color. The route still needs untangling.

Frostbank's pale blue snow, huts and rows of snowy obstacles.

How the hill
found its feet.

First, a grey board. Then four hills. Then one small rule change that made the whole thing easier to understand. Here are the turning points.

The plan

Sixty puzzles. Six rules.

The plan named four hills of fifteen puzzles each. Before there was snow or a scarf, a grey study sheet pinned down the shapes: kid, snowman, rock, hut, hole and thin ice.

Push, switch, stop, get home, watch the cracks, rewind. The game grew around those six ideas.

The first toy

The easy board went back.

The first toy was too short. A longer puzzle, Twin Cracks, became the test: could sliding, thin ice and rewind hold up together?

It could. The board stayed, but moved later in the game. A first lesson shouldn't ask you to untangle the whole mountain.

Snow & a coach

The hill gets a face. And a guide.

All sixty boards went in, then the original winter art: distinct hats for the kids, snowbank edges and a warning before a slide into a hole. Coach Pip followed with five practice boards, and nine layouts were retuned.

The game could teach its own first push.

Huts catch sleds

Huts learned to catch sleds.

Originally, a hut didn't stop a sled. The November 8 build changed that. An empty hut catches a kid; the kid inside blocks others and can slide out again.

Landing dots made the next stop visible, and the routes were rebuilt around the new rule. A little change to the destination changed the journey.

Newest update

A small nudge says “can't go.”

Press into an obstruction and the active kid gives a brief nudge. No move spent. Legal slides, switching, rewind and pause stay ready.
