UNDERFOOT: Earth Atlas

A puzzle with a mechanic you won’t find anywhere else: you stand on the board you are solving. Heavy slabs sink, light slabs rise — and when nothing is left beneath you, the layer you throw is you.

How it plays

The puzzle beneath your feet.

Step, shovel, lever

Three verbs, a handful of rules. Shovel the top slab of the ground you stand on onto a neighbouring column — and sink as you dig. The terrain you shape becomes your path.
A puzzle that plays fair

118 strata samples across 4 worlds. You get exactly as many shovels and levers as the best solution needs. No hints, no timers, no lives — undo as often as you like.
A new slice every day

Earth Mound opens a fresh board each day — Monday is the gentlest, Sunday the hardest.
A look all its own

Painterly strata, a living cinematic title painting and a calm soundscape. Section view lays every column side by side so you can read the whole board at a glance.

Painted strata of stone, terracotta and chalk

The idea

A world beneath your feet

Beneath every step lies a slow history: stone, terracotta and chalk, laid down layer by layer over millions of years. You are a surveyor for the Earth Atlas, a museum of strata.

The rules sort every column from heavy to light, so a solved board always looks like real sedimentary rock. The puzzle and the picture are the same thing.
