Survive. Tame. Idle.
The prehistoric world keeps turning — even while you're gone. A browser idle game of prehistoric survival: master thirteen skills, tame 57 species of dinosaur, raise a tribe of your own, and conquer ten savage biomes — then the Rifts beyond them.
You wash up in the Grasslands with empty hands and a hungry stomach. Pick berries. Knap flint. Cook what you catch. Before long you're smelting bronze, brewing potions, raising a tribe camp of your own, and staring down a Sarcosuchus wondering whether to fight it — or feed it until it follows you home.
Primal Idle distills the primal thrill of survival games into a clean, menu-driven idle game you can play anywhere. No downloads, no babysitting — just deep, interlocking progression that keeps moving even when you close the tab.
Come back tomorrow and the game tells you exactly what happened while you were gone.
Every skill is a gear in the same machine — and the machine never stops.
Foraging feeds your Cooking; Mining feeds your Smithing; Alchemy brews the tranquilizers your Taming depends on. From Farming to Delving, leveling one skill unlocks shortcuts in another.
57 species — from the humble Glyptodon to the Giganotosaurus — can be brought back to your stable. Every tame rolls its own stats, so no two raptors are alike — and a perfect-quality tame rolls perfect stats.
Assign a worker to each skill for boosts around the clock — but a hungry worker downs tools. Your stable isn't a trophy case; it's a workforce with a payroll.
Breed your best pairs, chase rare mutations, and stack generations of gains into a lineage worthy of the endgame.
Fight from the Grasslands to the Sundered Vale, clearing each region patrol by patrol until its apex guardian — Mosasaurus, T. rex, an Elder Quetzalcoatlus — steps out to meet you. Past the last biome, three rift zones tear open for the endgame.
A failed expedition can injure your party — unless your dinos are swift enough to flee. Brew salves, weigh the risk, and decide which beasts fight and which stay home and work.
Sell your surplus for amber, then spend it at the Amber Exchange on permanent upgrades — more bank space, more stables, faster tools, and satchels that stretch offline progress to a full 24 hours.
Everything runs on one clock, online or off. Your tribe keeps gathering, crafting, and hunting for up to a full day while you're away.
Wanderers find your campfire and stay. Set them gathering, running crafting lines, and standing the night watch against midnight raiders — then advance your whole camp through five material ages, from Stone to Obsidian and beyond.
Fifteen rival tribes hold the ladder above you, and eight rogue-clan outposts dot the valley. Raid the rivals for their war banners, then lay siege to the outposts — dueling ten named defenders and a boss, one bout at a time.
Eleven caves wind down to the Amber Door, each hiding a unique relic with a living effect. Between delves, run fossil dig sites and fill the museum with every skull in the valley.
Four story acts trace the war in the vale, with quest relics whose passives work straight from your bank. Achievement tracks, secret trials, and nemesis hunts that crown each biome's apex predator round out the chase.
