A polar colony strategy simulation
Tidehaven
Rival Rookeries
Hundreds of lives. One changing wilderness.
Guide your penguin colony through a breeding season and outcare a rival sharing the same coast. Manage fishing, shelter and nursery care in this 3D browser strategy game.
The seed and settings reproduce terrain, wildlife and the weather schedule.
Gentle snowfields → steeper ridges. Resource approaches remain traversable.
Broad land → wider waterways. Penguins swim faster but lose warmth.
Both colonies start equally. Breeding can add up to one-quarter more.
Mild fronts → harsher cold and wind. Forecasts give time to prepare.
Care is your strategy.
Fish, shelter and nursery space shape every decision. Your rival follows the same rules.
