Fusion Reactor

Three minutes to prove your reactor skills.

Grab nuclei, aim your throws and turn hydrogen into helium. Learn the proton–proton chain in a hands-on VR laboratory, then press the gold GO button: 3, 2, 1!

Discover what powers a star

• Follow seven narrated 3D tutorial steps, from stellar energy to making helium-4.
• Watch positrons meet electrons, neutrinos escape and gamma rays fly away.
• Explore heat and pressure with physical controls and a curved reaction guide.

Make every reaction count

• Tackle four reactor challenges within one three-minute run.
• Chain fusions for combos. Fewer fuel nuclei, lower heat and lower pressure earn more points; flooding the chamber has a cost.
• Chase five medals, from Operator to Chief Scientist. The top rank takes 7,000 points and six helium-4 nuclei before time expires.
• Hear a ringside announcer celebrate progress and encourage recoveries, with 20 variations for each of nine events.

When time runs out, see your medal, play again, revisit training or exit. Pause freezes the clock. Mute commentary while captions continue. Best scores and earned ranks stay on your device.

A stationary, single-player experience with no joystick locomotion. Tracked controllers and Internet required. Buy once; no in-app purchases, subscription or ads.
