RelativityRush
Race through warped spacetime
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Chase the next horizon through bending spacetime. Dodge cosmic hazards, ride photon currents and choose your path through the multiverse.
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, protect a run with a Quantum shield or slow the action with a Time dilator. Aim the Photon lance at breakable barriers. Collect gadgets on the course and use earned Quanta to upgrade them.
ONE MORE EXPEDITION
Build a clean-action chain, complete missions, take on Daily and weekly expeditions, and share a route challenge with friends. Practice previews let you explore the 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.
