Core Reactor: Idle Strategy

"Do I look like a button?" Meet the C.O.R.E. Eye, a mechanical eye that guards your reactor, comments on your every move and is sure it will win. Prove it wrong.

Core Reactor is idle strategy with attitude: duels against the Eye, Contracts that grow your base, and quick mini-games for every break. All of it powers an underground reactor that keeps working when you put your phone down.

👁️ DUEL WITH THE EYE
• A 5×5 board and one rule: an overloaded node hands charges to its neighbors and takes their cells.
• One good move can set off a chain across half the board.
• Three moods: Sleepy plays at random, Alert looks two moves ahead, Focused calculates three.
• The Eye reads your style. Collecting corners? Copying its moves? Clicking without thinking? You will hear about it.
• Tap the Eye and see what happens. It does not like being poked. Petting is another story.
• A short tutorial walks you through the rules on a real board. You win the first match, then the real game begins.
• Won? Share your result card and challenge your friends.

🧩 CONTRACTS: THE HEART OF YOUR REACTOR
Place Factories, Coolers and Generators on boards from 3×3 to 6×6, with blocked tiles, irregular shapes and Sources. These are 3-minute puzzles with no timer and three stars for optimization masters. Every Contract grows your base, and a new Daily Contract waits every day: the same board for every player. Want more? The Figures, Letters and Digits packs add 273 hard contracts.

🎮 THE GAMES TAB: SOMETHING FOR EVERY BREAK
• Core Cooling: hold the cores and don't let them hit 1000°. Cooling one heats its neighbor. A new reactor every day, the same for everyone.
• Power Line: tap a piece, rotate it and route the power to the exit. No move limit, no timer, and the stages never run out.
• Sector: place buildings on an isometric board. Three of a kind merge into a higher level, and your model base comes alive.
• Leaderboards: test yourself against others on daily and weekly boards.

🔋 A BASE THAT WORKS WITHOUT YOU
Your phone is the reactor. Charging gives Power, using your phone drives the Silicon Fabs, and while it rests, production carries on calmly. The Health Zone of 20–80% battery gives a ×1.25 bonus, because the game rewards healthy habits and never rewards heating your phone. Come back, collect your Return Report in 30 seconds and decide what to upgrade.

🏗️ BUILD, RESEARCH, REBOOT
Reactor, Capacitor, Silicon Fab, Cooler and Lab on a node map. A research tree, new Eras with fresh rules and Reboot, a prestige system that grants Blueprints for permanent Power, Silicon and Code upgrades. A day streak with Streak Shields helps you keep the rhythm.

🛡️ FAIR BY DESIGN
• Fully completable without paying.
• We never sell charging Power or Contract stars. No loot boxes.
• Rewarded ads are optional. One limited interstitial after collecting a Report, never during a Contract and never in your first 3 days. Operator Pro (one-time purchase) turns it off.
• No account needed. The game does not read your location, contacts, notifications or app usage stats.

Available in English and Polish. A round takes 20 seconds to 3 minutes, so you can play in a queue, on the bus or before bed.
