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 — 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 — 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.

Begin with one quiet world and turn it into an empire among the stars. Idle Stars is an incremental strategy game about connected systems. Build solar arrays, mines, laboratories, habitats, and spaceports. Balance five resources, research technologies that change how your economy works, and install AI Directors to automate each world while you are away. When your first planet is no longer enough, launch explorers into a living galaxy. Colonize new worlds, connect them into sectors, and meet civilizations with their own histories and strengths. Open talks, send envoys, or bring the fleet—the choices you make shape the empire and what the galaxy remembers. Eventually, growth reaches its limit. Trigger a supernova, carry stardust and permanent upgrades into a fresh universe, and push farther on every cycle. FEATURES • A layered idle economy built around energy, minerals, science, population, and influence • Research paths and automation that transform how worlds grow • A galaxy map with exploration, travel, colonization, and sectors • Civilizations that can be approached through diplomacy or force • Supernova resets with lasting progression • Offline progress and optional local notifications • Game Center achievements • Optional iCloud document sync between your Apple devices • Universal support for iPhone and iPad • No ads and no subscription The complete game is free. The optional Supporter Pack permanently unlocks three styles for planets, ships, and the app icon. You can also buy one hour of ×2 production: the timer runs in real time, even while the app is closed, and the multiplier never stacks above ×2. The optional Stellar Charter permanently multiplies all production by ×1.5, in every run.

Verdict
The clearest difference is in-app purchases: Deep Dig at none against Idle Stars's 3. Deep Dig also leads on update cadence (every 2 days vs every 3 weeks) and iOS requirement (15.0 vs 17.0). Idle Stars's advantage is ads (none vs shown). On price and device support there is nothing between them.
