Until Spring

Those survival ads that never looked like the game? Here it's real: pull the pins, dig hot baths, grow your crowd and keep the fire alive. No forced ads.

Keep one furnace burning through a frozen winter. Carry towers of logs, thaw survivors frozen in the ice, and build a camp around the warmth until spring comes.

Every rescue is a small puzzle of its own: pull the pins in the right order so the embers fall and the snow doesn't, dig a channel to bring hot water to a frozen survivor, or lead a growing crowd through the right gates to smash a wall of ice.

ONE THUMB Drag anywhere to walk. Chopping, carrying, feeding the fire and building happen when you walk up to them.

BRING EVERYONE HOME Twelve survivors wait out in the snow, sixteen in the later chapters. Each one you free follows you home, takes a bed and goes to work for the camp, and some bring gifts: wool mittens, a whetstone, hot coals, snowshoes.

EIGHT WINTERS, EACH ITS OWN RULES Pine Hollow, Wolf Pass, Frozen Lake, Whiteout Ridge, Glacier Mine, Avalanche Slope, Frozen Harbour and The Long Night. Torch posts to keep the wolves out of the light, bridges over thin ice, signal fires in the fog, a lantern in the dark of the mine, snow fences against avalanches, a lighthouse for the supply boat, and a last night with no dawn at all. Three stars to earn in every chapter, and Deep Winter to play them all again, colder.

ENDLESS WINTER How many nights can you hold the valley? Every night brings a danger and a goal. Meet it and pick a boon at dawn; miss it and the next night gets harder.

EVERY DAY, EVERY WEEK A daily rescue to keep a streak going, a weekly storm that brings back a chapter with new hardships, trophies to earn, and Game Center leaderboards and achievements.

THE HEARTH The embers from every run buy head starts, a tool for each danger, coats and camp looks, so every winter warms up the next.

NO FORCED ADS A short video only plays when you choose one, for a boost like thawing a survivor at once, relighting the fire once a run or doubling your embers. The optional Supporter Pack adds the animated Hearthkeeper coat, the Ember Aura and 2,000 embers. No account needed, and it plays offline.

Original music by day and by night, and a sound for every chop, crackle and crunch of snow.

Keep the fire alive.
