STRATA is a one-button idle digging game. The page itself is the earth's cross-section — every meter you dig changes the world's color as you descend through 11 eras of history, from fresh topsoil all the way down to THE CORE.

Topsoil → Modern Era → Industrial Age → Medieval → Roman → Bronze Age → Stone Age → Ice Age → Age of Dinosaurs → Primordial Depths → THE CORE.

Each stratum multiplies your coin value. Hire shovel crews, steam excavators, diamond drills and tunnel borers to keep digging while you watch the layers scroll by.

33 artifacts are buried in the strata — common, rare and legendary. Every find pays a coin burst and gives +2% earnings forever. Fill the museum grid, then "Publish Expedition" from 800 m for permanent Fame (+10% each) and start a deeper, faster dig.

One button. Tap DIG. Buy tools. That's it.

· Your dig continues while you're away (up to 8 hours of offline progress)

· Auto-saves every 10 seconds — close the tab, come back tomorrow

· Works on phone and desktop, one finger is enough

The whole game is a single HTML file with zero downloads and zero external requests. Made by TovPlay Studios — we build games with purpose.
