TERRA LOGICA
The more you play, the more you learn.
An educational sandbox game where kids learn by playing — answer questions, earn tokens, and build their unique world.
Build your world from scratch
The new island is randomly generated every time. Talk to characters, answer questions, earn tokens, and shape your own world.
How It Works
Explore the island, answer questions to earn treasures, trade them at the shipwreck, and rebuild the island with what you learn.
Explore
You crash-land on an uncharted island. Walk the beaches, woods and meadows and find the strange islanders roaming around.
Answer
Talk to the Automatons, Mermaids, Ghosts or the Wizard and they ask a question from their subject. Correct answers earn their treasure.
Trade
Bring your gears, shells, mushrooms and coins to the octopus Shipkeeper at the wreck and swap them for tools, seeds and building parts.
Build
Dig, till and plant with your tools, raise houses floor by floor, and turn the wild island into a place worth living in.
Four Characters, Four Subjects
Four kinds of islanders survived the wreck and roam the island — Automatons, Mermaids, Ghosts of the sailors, and the Wizard — each asking questions from a different subject. Every correct answer earns their own treasure, and those treasures buy everything you need from the Shipkeeper.
The Shipkeeper
TraderA giant octopus guards the shipwreck on the shore. Its hold has every tool, blueprint and seed you need to survive — but nothing is free. Trade the treasures you earned from the islanders (⚙️ gears · 🐚 shells · 🍄 mushrooms · 🪙 coins) for pickaxes, hammers, building parts, seeds and snacks.
The Automatons
MathToken: Gears ⚙️
Brass machines from the wreck's cargo — the only survivors of the hold. Solve number and logic puzzles to earn Gears before they power down and reappear elsewhere.
The Mermaids
LanguageToken: Shells 🐚
Mermaids leap from the sea onto the shore. Answer word and story questions to earn Shells before they dive back into the water.
The Wizard
ScienceToken: Mushrooms 🍄
The one and only survivor saved by his own magic. He fades in and out of the woods — explore nature questions to earn Mushrooms before he teleports away.
The Ghosts of the Sailors
HistoryToken: Coins 🪙
The lost crew of the wreck, still haunting the meadows. Uncover history and culture to earn Coins — then they vanish and reappear elsewhere.
One World, Shaped By You

Houses, structures, renovations
Growing
Vegetables, trees, plants

Grass, concrete, water
