Launch a scientist across the cosmos at near light speed — and try not to slow down. SpaceTime Sprint is a one-thumb arcade runner built on real physics. Steer left and right to weave through asteroids, black holes, and the strangest phenomena in the universe. Every hit drags you below light speed; stay clean to keep your distance climbing. DODGE THE UNIVERSE Solar flares, pulsars, quasars, gravitational lensing, quantum tunnelling, dark matter, supernovae and more — each is its own hand-crafted set piece with its own trick to read and beat. Discover new theories as you run and they unlock in your codex. A LAB THAT'S YOURS Between runs, explore your laboratory. Spend the Bits you collect on power-up particles, new scientists to fly, galaxy backdrops, and playful lab gadgets — tap the disco ball, the Tesla coil, Schrödinger's cat box, and more. POWER-UP PARTICLES Stock particles like the Neutrino, Electron, Higgs Boson, Dark Matter and Antimatter, then grab them mid-run for a burst of speed, double Bits, a shield, a Bit magnet, or a clean sweep of the field. LEARN AS YOU PLAY Every theory comes with a plain-English explainer and a literal how-to-play. Guided walk-throughs teach you the lab and the controls. It's an arcade game with a physics degree. CHASE THE LEADERBOARD Bank your furthest Light-second distance and your biggest single-run Bit haul, and climb the boards.
