Five faces, one planet
A cube for every corner of the planet.
Each color is a real issue. Solve a face, uncover the facts, then see what change looks like in the world.
How a level works
Three steps from puzzle to action.
Spin the cube
Rotate the faces and watch the pattern come together — the first step in noticing how connected systems work.
Uncover the fact
Crack the puzzle and a real environmental fact appears — the kind of thing you can act on today.
Learn, then act
QR codes connect each puzzle to a full story page where students turn what they learn into a real action.
Try a face
A tiny cube to play with right now.
Click a tile, watch the row twist. Noticing the pattern is the first move in every Eco Cube level.
What teachers say
Made for classrooms that don't sit still.
My students finally connected with climate change when they saw exactly how much ocean is threatened by rising temperatures. The cube made it real.

Connecting a fun puzzle to something they care about — that's the unlock. They're digging into real climate data and asking for more.
