Deep Dig
Read full descriptionHide full description
Deep Dig is an idle mining game built around one addictive question: will THIS tap be the big one? TAP TO DIG Smash through rock with every tap. Land a critical hit and a lamp lights up โ one more tap, and you break into a high-odds chain zone where crits can keep coming, tap after tap after tap. UPGRADE YOUR RIG Pour coins into Drill Power and Auto-Driller to dig faster, even while you are away. CORE UPGRADES + NEW GAME+ Reach the planet's core and earn permanent Cores, then start a fresh run with your upgrades carried over. Stack enough Cores across runs and your rig only gets stronger. PLAY IN YOUR LANGUAGE Fully translated into English, Japanese, Chinese, Spanish, Portuguese, and Korean. This release covers Stage 1 โ dig from the surface all the way down to 500m. Deeper stages, new ore, and more content are already in the works. Free to play, no purchase required. Optional video ads offer bonuses like stamina refills and coin boosts, entirely up to you. Start tapping. See how deep you can go.

Verdict
The clearest difference is in-app purchases: Deep Dig at none against Drill Kingdom's 7. Deep Dig also leads on update cadence (every 2 days vs every 4 weeks). Drill Kingdom's advantage is iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.
