Core Reactor: Idle Strategy

Who left the reactor on?! Three cores heating up at once, and all you have is your fingers. Hold, cool them down and don't let them hit 1000°. 🔥

Core Reactor is three games in one: fast-paced Core Cooling, a relaxing Power Line puzzle and Contracts, 3-minute brain teasers. All of it powers your underground base, which keeps working when you put your phone down.

🔥 CORE COOLING: 45 SECONDS OF ADRENALINE
• Hold the cores to keep their temperature in the green zone. Cool several at once.
• The catch: cooling one core heats up its neighbor.
• Power surges and stuck valves. You get a warning 1.2 seconds ahead.
• All cores in the green? Score ×2.
• Three levels: one core, a pair and a trio. A new reactor every day, the same for every player. Beat your daily best.

⚡ POWER LINE: ONE TAP, POWER ON
• Tap a piece to rotate it and route the power from the input to the exit.
• No move limit and no timer. The stages never run out.
• Challenges grow with you: power every piece, route two wires, L and N, without a short circuit, work around locked pieces.
• Stuck? A hint sets one tile, never the whole solution.

🧩 CONTRACTS: 3-MINUTE PUZZLES
Place Factories, Coolers and Generators on boards from 3×3 to 6×6, with blocked tiles, irregular shapes and Sources. No timer, with three stars for optimization masters. A new Daily Contract every day: the same board for every player. Want more? The Figures, Letters and Digits packs add 273 hard contracts.

🔋 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.

📱 WHO IT'S FOR
Fans of idle games, logic puzzles, quick arcade challenges and terminal-style sci-fi. A round takes 20 seconds to 3 minutes, so you can play in a queue, on the bus or before bed. Available in English and Polish.
