Cosmic Forge
Read full descriptionHide full description
Cosmic Forge is a deep offline idle game about turning a single iron vein into an interstellar mining empire. START SIMPLE Tap rocks. Upgrade your shaft. Automate with a baseline foreman. Watch a transporter shuttle ore from the mine to the refinery, then to the warehouse, where it sells for Coins. Every component โ shaft, transporter, refinery, warehouse โ has its own milestone multipliers every 10 levels, so progression keeps unlocking speed and capacity spikes. UNLOCK THE COSMOS Beyond Alpha Asteroid there are comet clusters, planets, moons, anomalies, and singularity zones. Each location type has its own production multipliers and warehouse sell rates โ anomaly-grade minerals pay poorly per second but richly per sale. HIRE MANAGERS Common managers enable auto-mining; bonus managers stack passive multipliers and trigger powerful active abilities (instant trips, production boosts, free upgrades). Assign them per mine. Some managers survive prestige. RESEARCH TREE 50+ research nodes across multiple branches โ economy, production, transport, offline efficiency, stock capacity, coin multipliers, prestige. Queue active research in parallel slots (expand via Galactic Research). Every tier you complete compounds. PRESTIGE FOREVER Perform a Stellar Reset when the cosmos is ready. Earn Stardust based on your total iron-equivalent across every resource. Spend Stardust on permanent upgrades that carry across runs. Eventually unlock Galactic Ascension โ a meta-prestige layer with its own research tree and Dark Matter currency. DAILY CHALLENGES Three challenges per day with streak rewards at 7 and 14 days. Missed days reset the streak but the game doesn't punish absence. OFFLINE EARNINGS Step away for up to a week โ Cosmic Forge continues mining at a tapered efficiency schedule and rolls a summary up on your return. Research that was in flight completes while you sleep. COMPLETELY OFFLINE No account required. No internet required. No ads. No in-app purchases. No subscriptions. No tracking. No analytics. No SDKs phoning home. GOD MODE (OPTIONAL) Want to test builds, skip a grind, or just play sandbox? God Mode is free for everyone โ a one-tap toggle in Settings (behind a "this may corrupt your save" warning, because it really can). First public release โ 0.19.0. Thanks for playing through 100+ pre-release builds with us.

Castle: The Eleventh Tower is a real-time strategy game about capturing towers and sending your army at the right moment. Drag from your tower to a target, choose how many troops to send and keep enough behind to defend your line. 10 CULTURES, 100 CHAPTERS Explore ten campaigns, from Gokboru and the Legion to the North and the Tide. Each culture has ten playable chapters. Capture enemy towers, defend your home tower, hold key objectives or survive a siege. ONE TARGET, THE RIGHT TIMING Send troops from several towers toward the same target. Learn Gokboru's Sรผrรผ Baฤฤฑ bond mechanic, adjust the share of troops you commit and time your special powers. Every captured tower opens a new tactical choice on the 3D battlefield. After becoming Essence-bound, reach a weakened target from two towers, spend Essence and hold the bond. Complete culture-specific boss objectives and equip earned guardian seals from your collection. BUILD YOUR CAMPAIGN Earn stars and gold from chapters. Complete daily quests and spend in-game gold on battle supplies, cosmetics and upgrades. Choose your supplies before entering the next battle. PLAY OFFLINE Single-player chapters work without an internet connection. Progress is saved on your device. Turkish and English interfaces, early gameplay hints and in-game help guide your first steps. The game may show interstitial ads between matches; ads require an internet connection. No ads are shown before you complete your first chapter. In the Store tab you can watch optional rewarded ads to fill gold chests; your counter is kept between sessions. Watching ads is never required and the campaign can be played without them. Defend your towers and begin your journey to the Eleventh Tower.

Verdict
The clearest difference is ads: Cosmic Forge at none against Castle's shown. Castle's advantage is update cadence (every 10 days vs every 5 weeks) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
