Ages 6+Dig deep with your little drill-bot! Find gems and fossils, upgrade your drill and battery, and reach record depths.
About This Game
One Little Bot, One Deep World
Treasure Drill is a cozy digging adventure about a small robot with a big drill. Tap the earth next to your bot to carve a path downward. Soft soil gives way instantly, grey rock takes a couple of digs, and dark hard rock demands a serious machine — while sparkling gems, ancient fossils, and glowing energy crystals wait in between.
Every dig spends one point of battery, so a trip down is a quiet puzzle in itself: which path gives the most treasure before the charge runs out?
Dig, Sell, Upgrade, Repeat
When the battery empties, the bot trundles home and sells its haul for coins. Coins buy the two things every digger dreams of: a better drill that clears rock in fewer hits, and a bigger battery for longer trips. Tin to bronze to silver to gold to the legendary Star Drill — each tier opens depths that were simply unreachable before.
- Tap any square next to your bot to dig it
- Gems and fossils become coins at the surface
- Energy crystals add +8 battery mid-trip
- Five drill tiers and five battery tiers to earn

Tips for Players
Energy crystals are worth a detour: +8 battery often pays for the whole side trip.
Dig around hard rock early on — it eats battery that softer detours would not.
Upgrade battery first: longer trips reach deeper, richer layers sooner.
The deeper the gem, the more coins it sells for — depth is profit.
Controls
