Gravity Courier

Read full description

You are a space delivery controller. Your only job: choose when, which way, and how hard to launch — then let gravity do the rest. Gravity Courier is a minimalist orbital puzzle built on real physics. The Sun, planets, and moons are genuinely orbiting in real time. There is no joystick, no thrust-and-steer. You read the dance of the planets, pull back a slingshot to aim, pick the launch moment, and fire. From there, gravity alone bends your probe's path — so a straight shot will never work. Predict the curve, use a planet's pull, and arrive exactly on target. WHY IT FEELS DIFFERENT • Real orbital mechanics — Keplerian planet motion + true n-body gravity on your probe. Deterministic, fair, and endlessly satisfying to "solve." • One decision, infinite depth — only date, direction, and thrust. Easy to grasp, hard to master. • A living solar system — Mercury to Neptune orbit at their own speeds. Change the launch date and the whole board lines up differently. MISSIONS ACROSS THE SOLAR SYSTEM • Orbit — loop a planet or moon without escaping or crashing • Flyby & return — swing around the Moon's far side and let gravity sling you home • Landing — enter a gravity well and settle into a soft touchdown • Reach — time an interplanetary transfer to meet a moving planet where it will be • Gravity assist — skim a giant planet and steal a free push • Orbital cleanup — ram drifting space debris before it spreads FEATURES • 90+ handcrafted missions across the Sun, Moon, Venus, Mars, Jupiter, Saturn, and the outer planets • Predicted-path preview with a closest-approach marker — line up the gap and you'll hit • Reserve a mid-flight boost on your trajectory, or fire it by hand • Star ratings reward fuel economy and fast transfers — chase that 3-star run • Replay any flight and share it as a trajectory image card • Clean, quiet, starfield aesthetic with a calming soundtrack • 13 languages • Play offline • One-time "Remove Ads" available No timers pushing you. No pay-to-win. Just you, the planets, and one perfect launch. Read the orbits. Launch right. Safe orbits, courier.

You get a comet and one pull of the sling. Gravity does everything else. Drag anywhere on the field, watch the dotted line trace the first second and a half, and let go. The comet leaves the pad in the opposite direction and starts weaving between dwarf stars. A close pass heats one. At a hundred percent it shudders, melts and goes supernova. From there it is out of your hands. The shock ring does three things at once: it kicks the comet onto a new course, hands neighbouring stars half their heat, and burns the dust in its path — worth more the deeper the chain runs. Neighbours catch, their rings chase the comet, the comet threads between overlapping fronts, and the sector takes itself apart. You do not steer it. You choose where it starts. HOW IT WORKS • A star heats from a close pass — the closer and longer, the faster • At 100% a fuse burns under a second, then the supernova • The shock ring: +30% speed to the comet, +50% heat to neighbours, dust burned at the chain's depth multiplier • Dust lies along the lines between stars — exactly the routes a chain will travel • A dead star no longer pulls, so late in a round the field straightens its own trajectories THREE SHOTS, ONE FIELD The rule the game rests on: the field is NOT reset between shots. Heat never cools, burned-out stars stay burned out, vaporised dust never comes back. The first shot arms, the second finishes. That is why a chain happens even when you aimed roughly both times — and why precise aim turns it into one unbroken cascade. Everything burned out early? The "Enough" button closes the sector right there. WHAT'S INSIDE • Endless campaign: more stars, tighter charge radii, shorter shock rings • Three stars per sector at 35%, 62% and 88% of luminaries gone nova. One star opens the next • Every sector is procedural but always the same one: its seed comes from its number • An eight-knob builder — build a field and see what it can do • A replay code under every result plays back the same round • English and Russian, switched in settings • iPhone and iPad: the field fills the screen, never a phone layout with bars ABOUT ADS Rewarded video is always your choice, and there are two. If the sector isn't cleared — two more shots at the same field: the damage and the score stay. And between shots — the sector hint: a cone that says "roughly there", not an exact angle. Measured: a shot from the hinted sector destroys about a third more luminaries than a random one, while the globally best angle falls inside it only once in eight. The interstitial comes AFTER the result screen, once every three sectors, never mid-round. No in-app purchases, subscriptions, accounts, chat or user content. The game runs fully offline; the network is only for ads.
