Plutonium Ore

Plutonium Ore puts you in charge of a compact breeding reactor where every swipe counts.

Slide the isotope tiles across a 4x4 reactor core. When two identical isotopes collide they fuse into the next heavier step of the breeding chain: U-238 becomes U-239, then Np-239, then the legendary Pu-239 and beyond. Every fusion releases energy units, the currency that fuels your run.

Achieve CRITICALITY by breeding your first Pu-239 tile and claim a one-time energy bonus. Push further into the transuranic elements and chase a new personal best score before the core jams completely.

Features:
- One-finger swipe controls, easy to learn, hard to master
- A full isotope breeding chain from uranium to californium
- Energy economy with a Core Shop: Undo modules, Core Shuffles and reactor skins
- Three reactor visual themes to unlock
- Synthesized retro sound effects and haptic feedback
- Offline play, progress and best score saved locally

Strategy tips: pin your heaviest isotope in a corner, feed the chain toward it, and save your Shuffle charges for the endgame when the core starts to lock up.

No ads. No accounts. Just you, a reactor, and the pursuit of critical mass.
