RelativityRush
Race through warped spacetime
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Four scientists. One multiverse. Dodge supernovas, ride shifting roads and dive through portals. How far can you rush?
Space is your racetrack. Gravity keeps changing the rules.
Run across a luminous spacetime grid in a physics-inspired arcade adventure. Choose from four scientists as you unlock them through gameplay, each with a unique ability. Swipe between lanes, leap over rifts and slide beneath obstacles as the pace builds.
FOUR SCIENTISTS. FOUR UNIQUE ABILITIES.
Start with Albert Einstein and unlock three more scientists through gameplay:
Albert Einstein - Dash: Race forward with a protected lightspeed burst.
Hugh Everett - Portal: Open a shortcut and jump ahead along the course.
Marie Curie - Extend: Double the remaining time of your active power-ups with two free uses each run. Unlock a permanent third use for 5,000 Quanta.
J. Robert Oppenheimer - Nuclear strike: Launch a missile that clears nearby obstacles with an expanding blast.
Choose your scientist, master their ability and push your personal best farther. Preview characters and outfits in the Wardrobe and choose your field equipment.
A CHANGING COSMIC COURSE
Navigate narrowing wormholes, gravity bends, asteroid showers and cosmic-string obstacles. Choose a multiverse path and watch the road climb into a different landscape. Race through black-hole encounters beneath a moving universe of stars.
GADGETS FOR THE NEXT CLOSE CALL
Draw in Quanta with the Magnetar and protect a run with a Quantum shield. Use your scientist's ability when the course gets dangerous, and use earned Quanta to upgrade your equipment.
ONE MORE EXPEDITION
Follow a connected rescue campaign to find Everett, Curie and Oppenheimer. Track the next scientist from Home and inspect requirements in Missions. Earn research reports through expeditions and daily fieldwork, collect permanent notebook stamps, and take on Daily and weekly challenges. Share a route challenge with friends or use Practice previews to explore cosmic encounters without risking earned progress.
YOUR PACE, YOUR SETTINGS
Adjust graphics quality, ambient motion and sound. Save and export your earned progress from Settings.
Optional in-app purchases offer Quanta and a cosmetic outfit. Quanta have no cash value. Purchases and purchased-wallet services require an internet connection. Earned progress and purchased items use separate recovery systems; see in-game support for details.
Follow a connected rescue story to find Everett, Curie and Oppenheimer. Track the next scientist from Home, inspect rescue requirements in Missions, and progress through expedition achievements or cumulative research.
Complete daily fieldwork to earn Quanta, research reports and notebook stamps. Discover additional milestones and a daily hard challenge.
This update also includes new gameplay models for all four scientists, revised Home and run controls, updated cosmic skies and portals, and changes to Meissner and Graviton challenges. Supernova impacts now land farther ahead of the runner. Run equipment centers on Shield, Magnetar and scientist abilities.
Existing scientist ownership and earned progress are preserved.
