The stations of Expedition Island

Volcano Rim Camp
Dig into Earth's deep past — dinosaurs, ancient Egypt, and the maps explorers live by.

Moon Deck Observatory
Tour the solar system, then crack the science of color and sound.

Robot Hangar
Fractions run every machine in here. Slice them, build them, balance them.

Code Shack
Turn, flip and fit the pieces until the puzzle clicks.

Reef Dive Dock
Read like a field scientist, fix sentences that went wrong, and see how your body works.
For grown-ups
- Every station runs a real Koydo activity — the same one members play.
- Your child can start right away: no account, no email, no card.
- Nothing on the island asks your child for money or personal details.
Every station on the island has free activities — play them as often as you like.
To continue, press and hold the button for three seconds. This helps us make sure a parent or guardian is present.
