UNDERFOOT: Earth Atlas

Beneath every step lies a slow history: stone, terracotta and chalk, laid down layer by layer over millions of years.

In UNDERFOOT you are a surveyor for the Earth Atlas, a museum of strata. Each sample is a quiet puzzle on a small grid of earthen columns. Step, shovel and lever the slabs until every column shows the layers the museum asks for.

ONE VERB, DEEP CONSEQUENCES
• Shovel the top slab of the ground you stand on onto a neighbouring column.
• Heavy slabs always sink to the bottom; light slabs always rise to the top.
• Stand on empty ground and shovel toward a tall column — the layer that gets thrown is you. A lever that lifts you up.

A PUZZLE THAT PLAYS FAIR
• 118 strata samples across 4 worlds, from the first traces to the deep core.
• The first 12 samples teach the rules at your own pace.
• In the other 106, you get exactly as many shovels and levers as the best solution needs. Stepping is always free.
• No hints, no timers, no lives. Undo any move 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 — on a calendar of 728 days.

MADE TO BE SAVOURED
• 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 once.
• 10 languages, iPhone and iPad, fully offline.
• One purchase. No ads, no in-app purchases, no data collected.
