Undersoil
Read full descriptionHide full description
Somewhere under this beach is everything anyone ever lost. Undersoil is a pixel-art dig-and-collect game about the slow, satisfying business of finding things. Sweep a metal detector along the shoreline until a beam of light marks a spot. Dig it out. Carry it home. Brush the dirt away by hand and find out what you actually pulled up โ and how well it survived down there. Then the only decision that matters: sell it, or put it on a pedestal where everyone can see it. THE LOOP โข Sweep the sand until the detector finds something โข Dig it out on the tap bar before the dirt wins โข Carry the find overhead to the cleaning table โข Spray and scrub off the grime by hand to see what you've got โข Watch the condition land: OK, Fine, Good, Excellent, Mint or Pristine โข Sell it for cash, or display it and let it earn gold while you are gone 159 THINGS TO FIND Bottle caps and fish bones near the top. Crowns, meteorites and things that have no business being buried on a beach a long way below. Twelve rarity tiers run from Common to Primordial, and only your single best specimen of each earns a pedestal โ turn up a better one and the old one gets bumped. SIX LEVELS DOWN Home Beach is only the lid. Take the miner's cart down through The Undersoil, The Deep, the Lava Pools, the Sulphur Sink and the Abyssal Trench. Each level buries richer things and asks for better gear to get them out. GEAR THAT EARNS ITS KEEP Shovels, detectors, sprays and bags, five tiers deep at every level. A better detector finds more. A better shovel digs faster. A bigger bag means fewer walks back. A MUSEUM THAT PAYS Thirty pedestals on the sand. Everything you display earns gold in plain sight, and keeps earning while the app is shut. Tourists wander in to admire the good ones. ALSO โข Plays offline; cloud save keeps your progress if you reinstall โข No account, no sign-up, no email address โข Seventeen languages โข Free to play. Rewarded ads are always your choice, and there is never a full-screen ad in your first session.

Verdict
The clearest difference is in-app purchases: Hex Defense at none against Undersoil's 3. Undersoil's advantage is update cadence (daily vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
